00:00:00Look at the ceiling. Do you see your fan?

00:00:03If you don't have one, pretend you have one.

00:00:06There is a hidden function that you probably don't know.

00:00:09It can be a switch on the fan itself or a button on the remote control.

00:00:14But most fans have the ability to change direction,

00:00:18and there is a reason why you want them to do it.

00:00:21In winter, you want them to turn clockwise,

00:00:24which pushes the hot air from top to bottom.

00:00:26In summer, you want them to turn counterclockwise,

00:00:29which pushes the hot air from top to bottom and circulates it in the room.

00:00:35Your microwave probably has a silent mode.

00:00:38Yes, this dish that you heated at 3am

00:00:41by leaving your finger just above the stop button to press it for a second,

00:00:45before the timer started, could have been a lot less noisy.

00:00:49It depends on the brand, but by now pressing the 0 or 1 button,

00:00:53you should be able to activate the silent mode.

00:00:55Now you can use the microwave at any time of the day and night.

00:01:00These spring-loaded doors on the plinths have another function.

00:01:04They allow you to hold the door.

00:01:07By placing them on the floor and opening the door above it,

00:01:11the spring clings to the bottom of the door and holds it open.

00:01:15Did you know that you probably miswound your sneakers all this time?

00:01:20There is a small hole at the top, where the laces end,

00:01:23which is called a heel lock.

00:01:25Can you guess what it's for?

00:01:27Yes, it locks your heels so that they don't slip and don't give you a light bulb

00:01:31or make your socks slip down.

00:01:33Which is the worst feeling, isn't it?

00:01:36All you're supposed to do is put each lace through its hole,

00:01:40which creates a small loop.

00:01:42The opposite lace then goes through this loop.

00:01:45Tie your laces tightly, as you would normally,

00:01:48and there you go, your heels are secure.

00:01:51Speaking of laces,

00:01:53if you ever tie them so tightly that you can't undo them,

00:01:57a pastry ingredient has a hidden feature that can help you.

00:02:01Yes, you heard that right, a pastry ingredient.

00:02:05Corn starch can certainly make your sauce thicker,

00:02:08but it can also undo stuck knots.

00:02:11All you have to do is sprinkle it on any knot by wrapping it completely,

00:02:15and it will come undone more easily.

00:02:17You can do this with necklaces, ropes, or thread.

00:02:21You put your friend's ring on,

00:02:23forgetting that his hands are much smaller than yours,

00:02:26and now it's stuck.

00:02:28Just take a bottle of glass cleaner.

00:02:30This product has a small hidden feature to remove stuck rings.

00:02:34A little splash, and the ring will come undone right away.

00:02:39Let's say you're writing something on a pencil,

00:02:42during an exam, for example,

00:02:44but, oops, you forgot your eraser.

00:02:46You didn't forget to bring your sandwich.

00:02:48Luckily, the bread is what you need

00:02:50to erase the wrong answer you just wrote.

00:02:54Roll up some compact breadcrumbs

00:02:56until it has a texture that can be described as rubber.

00:03:00Then, erase as you would with real rubber.

00:03:03Why do bakers always hide this from us?

00:03:06It could have been useful in so many situations.

00:03:09If you wear a leather jacket,

00:03:11first, you're cool.

00:03:13And second, you're probably missing the use of a hidden feature

00:03:17that everyone can see.

00:03:19The straps on the top of the shoulders of your jacket

00:03:22are not only decorative.

00:03:24If you unbutton them while you slip the straps of your bag,

00:03:27you can close them over the straps

00:03:30to keep them in place.

00:03:32No matter how many jumping jacks, wheels,

00:03:35or breakdances you're going to do,

00:03:37your bag won't go anywhere.

00:03:39When you have to pack leftovers,

00:03:41aluminum foil is clearly a valuable ally.

00:03:44But it also has a place in the mess

00:03:46thanks to a hidden feature.

00:03:48Imagine you don't have any more sheets to dry your clothes.

00:03:51Your clothes come out of there full of static electricity,

00:03:54so much so that they make your hair stand up

00:03:56like those of an evil cartoon scientist.

00:03:58Here's what you have to do.

00:04:00Make two very compact balls with aluminum foil.

00:04:03Put your clothes back in the dryer with the balls

00:04:06and restart a drying cycle.

00:04:08They'll come out of there without static electricity.

00:04:11After you've cooked some hard-boiled eggs,

00:04:14how do you get them out of the boiling water

00:04:17without burning your fingers?

00:04:19With a kitchen whip.

00:04:21Push it against the egg

00:04:23and it will get stuck between the whips.

00:04:25You can now get it out easily.

00:04:27The colors of the bread bag clips

00:04:30actually have a secret meaning.

00:04:32They tell you the day of the week

00:04:34when the bread was packed.

00:04:36Yellow means Monday, brown means Thursday,

00:04:39and white means Friday.

00:04:42Most bread manufacturers follow the same system

00:04:45because a particular company provides most of its clips.

00:04:49So when you choose bread,

00:04:51you can evaluate its freshness

00:04:53thanks to the color of the clip.

00:04:55There's nothing better than a slice of toasted bread

00:04:57with butter for breakfast,

00:04:59except for sundaes with melted caramel.

00:05:01If you find it difficult to spread your cold butter on your bread,

00:05:04here's an idea.

00:05:06Use a cheese grater.

00:05:08But remember the amount of butter you need.

00:05:11This way, the necessary amount of butter will soften

00:05:15and it will be easier to spread.

00:05:18But still, the melted caramel...

00:05:21There are different shapes and sizes of dry pasta

00:05:23for a reason.

00:05:25Each type of pasta goes perfectly

00:05:27with a certain type of sauce.

00:05:30Conchiglioni, for example,

00:05:32are perfect with a thicker sauce.

00:05:34Why?

00:05:36Because the sauce goes into the shells

00:05:38and makes the dish easier to serve.

00:05:41The stripes on the surface of the pasta

00:05:43keep the sauce in place.

00:05:46If you ever burn your biscuits...

00:05:48Oh no!

00:05:50You can get them back with your favorite cheese grater.

00:05:53Just grate the burnt parts

00:05:55once the biscuits have been removed from the baking tray.

00:05:57But be careful!

00:05:59Wait until they've cooled down.

00:06:01If you ever burn the burnt parts,

00:06:03just dip them in melted chocolate.

00:06:06Once the chocolate hardens,

00:06:08you'll have perfect biscuits.

00:06:10But let's be honest.

00:06:12Does the shape of the biscuit really matter

00:06:14when you taste it?

00:06:16I'm just saying.

00:06:19If you make sandwiches with lots of ingredients

00:06:22but you don't want the bread to be soft,

00:06:25there's a technique to prevent that from happening.

00:06:28Take the tomatoes or cucumbers

00:06:30you want to put in your sandwich

00:06:32and place them between two paper towels for 5 minutes.

00:06:34There you go.

00:06:35You can put them in the bread.

00:06:37Make sure to spread the butter,

00:06:39cheese or sauces like mayo or ketchup

00:06:41on the bread first.

00:06:43This will seal the bread

00:06:45and prevent it from softening.

00:06:47Some people think

00:06:49you have to remove this little white filament

00:06:51next to the egg yolk

00:06:53before cooking it.

00:06:55I'm here to tell you that these filaments

00:06:57are called chalazes.

00:07:00They're there to hold the yolk in place

00:07:02in the middle of the egg.

00:07:04Chalazes don't affect the consistency

00:07:06and taste of your food.

00:07:08It's up to you whether you want to remove them or not.

00:07:11Have you ever noticed that the bricks

00:07:13of the juice have two tabs on the sides?

00:07:15They're actually handles.

00:07:17Manufacturers designed these bricks

00:07:19this way

00:07:21so that we can handle them more easily

00:07:23without crushing them

00:07:25and taking the juice out.

00:07:29You don't need to be a star chef

00:07:31to know that you can use white sugar

00:07:33or brown sugar in all your recipes.

00:07:35Have you ever wondered

00:07:37what the difference between the two was?

00:07:39It turns out that the only thing

00:07:41that differentiates them

00:07:43is the production method.

00:07:45A small amount of molasses

00:07:47is added to the brown sugar.

00:07:49Molasses is a kind of syrup

00:07:51obtained during the transformation

00:07:53of the sugar cane.

00:07:55This is what is removed

00:07:57from the white sugar.

00:07:59But if a certain amount of molasses

00:08:01remains in the final product,

00:08:03we get brown sugar,

00:08:05which has a stronger taste

00:08:07and a darker colour.

00:08:09It's a good thing.

00:08:11You can put a lot of things

00:08:13in your dishwasher,

00:08:15not just plates and cutlery.

00:08:17For example, you can wash

00:08:19your kitchen gloves in silicone,

00:08:21the pommels of some household appliances

00:08:23like those in your oven

00:08:25or your dishwasher.

00:08:27Speaking of household appliances,

00:08:29you can do a lot of things

00:08:31with the dishwasher.

00:08:33You can clean your garden furniture,

00:08:35for example,

00:08:37add a little dishwasher liquid

00:08:39to hot water and use this mixture

00:08:41to rub all your garden furniture

00:08:43with a piece of fabric.

00:08:45Rinse them with your watering pipe.

00:08:47You can also use your dishwasher

00:08:49to remove the grease stains

00:08:51from your clothes,

00:08:53but it happens to all of us

00:08:55to miss our mouth.

00:08:57Put a little dishwasher liquid

00:08:59on the stain and rinse with water.

00:09:01For light clothes,

00:09:03it's better to use non-coloured liquid.

00:09:05For the most tenacious stains,

00:09:07let the dishwasher liquid

00:09:09act for a few minutes

00:09:11then put the clothes in the machine

00:09:13as usual.

00:09:15And buy yourself a bottle,

00:09:17maybe.

00:09:19If you still haven't found

00:09:21one, it's the one-of-a-kind technique.

00:09:25For every piece of clothing you buy,

00:09:27you have to get rid of an old one.

00:09:29You will regularly

00:09:31unpack your wardrobe.

00:09:33To find things more easily,

00:09:35good luck,

00:09:37leave the clothes you use most often

00:09:39at the level of your eyes.

00:09:41You will be able to find them more easily

00:09:43and take them out of the wardrobe quickly.

00:09:45Clothes you use less often,

00:09:47like evening clothes, for example,

00:09:49can be found at the level of your eyes.

00:09:53The old boxes can be very useful.

00:09:55If you stick very powerful magnets

00:09:57inside,

00:09:59they can serve as magnet containers.

00:10:01You can store a lot of objects there,

00:10:03like kitchen tongs,

00:10:05ice spoons or even cutlery.

00:10:09You can put them on any metal surface,

00:10:11like the door of your fridge.

00:10:13They will go very well

00:10:15with the rest of your magnets.

00:10:17At the bottom of your laundry,

00:10:19you have an essential tool

00:10:21to pick up animal hair.

00:10:23It even works better

00:10:25than adhesive rollers.

00:10:27These are clothespins for dry clothes.

00:10:29One of these clothespins

00:10:31and a little elbow grease

00:10:33and you're done.

00:10:35No more hair everywhere.

00:10:37It works on all surfaces,

00:10:39but it is particularly effective

00:10:41on cluttered furniture.

00:10:43If you don't want your doors to scratch

00:10:45the floor,

00:10:47you can leave it like this

00:10:49for a while,

00:10:51but it will be fine

00:10:53until you go to a DIY store

00:10:55to buy lubricant,

00:10:57for example.

00:10:59You have already noticed

00:11:01that in some elevators

00:11:03there is a star

00:11:05next to this or that floor.

00:11:07And no,

00:11:09this is not to indicate

00:11:11the floor of my office.

00:11:13But why are the stop signs red?

00:11:15Some time ago,

00:11:17there were no specific colors.

00:11:19Before 1920,

00:11:21there were not even standard shapes.

00:11:23In 1922,

00:11:25someone had the idea

00:11:27to impose the octagon.

00:11:29But at first,

00:11:31these signs were yellow.

00:11:33The red faded too quickly

00:11:35because of the exposure to the sun.

00:11:37Yellow was the best option.

00:11:39It was only 30 years later

00:11:41that a more resistant color

00:11:43was invented.

00:11:45It is then that the color of the stop signs

00:11:47became red.

00:11:49After all,

00:11:51it is the best color

00:11:53if you want something

00:11:55to be easily spotted.

00:11:57Did you know that there is

00:11:59a type of rosette

00:12:01that grows higher than a man?

00:12:03According to the Guinness Book of Records,

00:12:05the highest rosette

00:12:07that has ever existed

00:12:09is a tiger.

00:12:11Like our digital footprints,

00:12:13which are unique,

00:12:15there are no tigers

00:12:17with the same stripes.

00:12:19This is how people

00:12:21who work with these big felines

00:12:23distinguish them from each other.

00:12:25I bet you didn't know

00:12:27that the Maison Blanche

00:12:29has its own florist in the basement.

00:12:31This business deals with ornaments

00:24:49to the end of the cord.

00:24:51It's called a ferrite core.

00:24:54It's a magnetic iron oxide

00:24:56that stops electromagnetic interference at high frequency.

00:25:00You see, for example, this annoying static noise

00:25:02that you get if you bring your phone

00:25:04too close to a speaker.

00:25:06It interferes with your call.

00:25:08That's why cable cords with large cylinders

00:25:10are rather useful,

00:25:11because they prevent this kind of thing.

00:25:15Do you know why almost all luggage bags

00:25:17and backpacks have two zippers?

00:25:19It's much easier and more practical

00:25:21to open it this way.

00:25:23But that's not all.

00:25:24You can also lock these two sliding zippers together

00:25:26so that the things inside your bags

00:25:28are safe.

00:25:30You know how public places' toilets,

00:25:32like malls,

00:25:33have these large spaces at the bottom of the door?

00:25:36It's mainly for better air circulation.

00:25:38This type of door also allows you

00:25:40to clean the toilets more easily

00:25:42or check if they are occupied when you wait.

00:25:45Apart from that,

00:25:46if you are stuck inside

00:25:48and the lock is broken,

00:25:50you always have a way to escape.

00:25:52You can just crawl out.

00:25:54Have you ever noticed these plastic tips

00:25:56on the cutters?

00:25:58The blade also has a notch,

00:26:00which indicates that you can renew it several times,

00:26:02always with sharp edges.

00:26:05You can separate these pieces of blade

00:26:07with these plastic tips.

00:26:09Then you just have to move the sliding part

00:26:11to push this new blade forward.

00:26:14If you have already taken a moment

00:26:16to look at a Lambda supermarket cart,

00:26:18especially its foldable section,

00:26:20you have probably noticed

00:26:22these metal loops that protrude.

00:26:24They are designed to protect the items

00:26:26you carry in your cart.

00:26:28You can use them to hang bags

00:26:30containing soft items,

00:26:32such as bread,

00:26:34which you do not want to accidentally crush

00:26:36with heavier products,

00:26:38or things that are more easily broken,

00:26:40such as eggs.

00:26:42If you are a fan of McFlurry,

00:26:44you have probably already noticed

00:26:46that there was a square hole

00:26:48in the handle of their spoon.

00:26:50It is there so that you can attach it

00:26:52to this special machine

00:26:54that mixes the ice cream

00:26:56with your favorite toppings.

00:26:58The machine has a bar that slides

00:27:00into this square-shaped spoon

00:27:02and that moves it around

00:27:04so that the ice cream

00:27:06does not fall out of the spoon.

00:27:08It is there so that you can

00:27:10attach it to this square-shaped spoon

00:27:12and that moves it around carefully.

00:27:14And you are given this spoon

00:27:16to minimize damage during the process.

00:27:18Pretty cool, isn't it?

00:27:20An ordinary can of milk

00:27:22usually has a bump on the side.

00:27:24Some may see

00:27:26a random design choice,

00:27:28but this bump fulfills several objectives.

00:27:30One of them is to inflate

00:27:32if there is an accumulation of gas.

00:27:34This happens when your milk has turned.

00:27:36So you don't even need to taste it

00:27:38to check.

00:27:40In addition, the bump is there

00:27:42so that the bottle does not burst

00:27:44if you drop it accidentally.

00:27:46It allows an expansion space

00:27:48that takes in the sudden pressure

00:27:50that occurs when you drop the bottle.

00:27:52The dental floss.

00:27:54It is obviously important

00:27:56to take care of your teeth

00:27:58and it is easy to guess

00:28:00how to use it.

00:28:02But it is also great in the kitchen

00:28:04because it is a very precise cake cutter.

00:28:06Most kitchen scissors

00:28:08have a dent opening

00:28:10right here in the center

00:28:12where the blades and handles meet.

00:28:14This is something you can use

00:28:16to trim difficult herbs

00:28:18like thyme or rosemary.

00:28:20Thanks to this opening,

00:28:22you don't need to remove the leaves by hand

00:28:24but you can tear them all

00:28:26in one move.

00:28:28A large part of yogurt or flan skins

00:28:30are supplied with an aluminum paper lid.

00:28:32And in most cases,

00:28:34you can use this lid

00:28:36as a disposable spoon.

00:28:38You just have to take it off

00:28:40and after a few simple folds,

00:28:42you will have a small spoon

00:28:44perfect for your 4 hours.

00:28:46If you see it in the street,

00:28:48you tell yourself that a fire mouth

00:28:50measures about 1 meter high.

00:28:52But the real size of this device

00:28:54used to supply water to firefighters

00:28:56around the world is twice as large

00:28:58if we count the rest of the fire mouth

00:29:00that is hidden underground.

00:29:02And it's not just a matter of urban design.

00:29:04First of all, they must be bright

00:29:06and easily identifiable

00:29:08so that firefighters can locate them quickly

00:29:10in case of need.

00:29:12In the USA, the choice of color

00:29:14depends on the amount of water

00:29:16that the fire mouth can contain.

00:29:18This can sometimes vary

00:29:20depending on the location

00:29:22but here is the logic.

00:29:24A red fire mouth can project

00:29:261,890 liters of water per minute

00:29:28while an orange one

00:29:30can provide

00:29:325,680 liters of water per minute.

00:29:34And the biggest ones,

00:29:36blue ones,

00:29:38can generally provide

00:29:40more than 5,680 liters.

00:29:42Hi bowling fans!

00:29:44It doesn't bother you

00:29:46that your bowling ball cracks?

00:29:48It turns out that most of them

00:29:50can be damaged

00:29:52due to poor storage

00:29:54or temperature peaks.

00:29:56Now let's be honest.

00:29:58A bowling ball is made of metal powder

00:30:00like calcium oxide or iron.

00:30:02It is mixed with resin and a catalyst

00:30:04to harden everything.

00:30:06Thus, the shape of the ball

00:30:08is its heaviest part.

00:30:10It also influences the way

00:30:12the bowling ball turns

00:30:14when it crosses the track.

00:30:16The same goes for paint bombs.

00:30:18When you shake it,

00:30:20it makes a strange noise.

00:30:22But what is this thing inside?

00:30:24It is a small weight

00:30:26It is generally made of plastic,

00:30:28metal or ceramic.

00:30:30It is mainly used as a whip

00:30:32to ensure that the paint is well mixed

00:30:34before applying it on the surface of your choice.

00:30:36Have you ever wondered

00:30:38how the bottles of sparkling water

00:30:40kept this sparkling so refreshing for so long?

00:30:42Well, they have a small plastic seal

00:30:44attached to the lid.

00:30:46It is installed here to prevent the gas from escaping

00:30:48and the drink from becoming flat,

00:30:50even if you shake it in your bag all day long.

00:30:52Speaking of things

00:30:54that we use when it is very hot.

00:30:56Wait, wait, don't put on your cap yet.

00:30:58Look at it for a moment

00:31:00and you will notice that there is a small button at the top.

00:31:02It is used for something

00:31:04or it is just there to look pretty.

00:31:06Some claim that at the time

00:31:08when people started using such stitches

00:31:10to cover their heads,

00:31:12this button was used for something.

00:31:14As it is above the cap,

00:31:16where all the pieces of fabric meet,

00:31:18the upper button helps to keep

00:31:20the crown of the cap in one piece.

00:31:22As it is above the crown,

00:31:24this button has become an aesthetic element.

00:31:26It is used to cover the part

00:31:28where all the pieces of fabric meet.

00:31:30Your cap may not have a button,

00:31:32but don't you think it is nicer with it?

00:31:34Cotton discs have two sides

00:31:36and if you take the time

00:31:38to look at them carefully,

00:31:40you will see that they have different textures.

00:31:42In case you are wondering why,

00:31:44the side with the texture is used to put on the makeup

00:31:46and the flat side is used to remove it.

00:31:48Book lover, this is for you.

00:31:50The jackets that come with many books

00:31:52with a rigid cover are not only

00:31:54intended to embellish the book.

00:31:56They can also serve as bookmarks.

00:31:58You just have to fold the pages

00:32:00that you have already read

00:32:02under the inside of the jacket and that's it.

00:32:04The next time you take your favorite shirt,

00:32:06take a look at the buttonhole at the top.

00:32:08It must be sewn horizontally

00:32:10while all the others are vertical.

00:32:12It turns out that the city shirt

00:32:14was designed this way

00:32:16since the first and last button

00:32:18They therefore modified the meaning of the buttonhole

00:32:20so that the shirt stays well adjusted

00:32:22before you are ready to remove it.

00:32:26Nowadays, we have so many different versions

00:32:28of this incredible dessert that it is difficult

00:32:30to imagine that we could have lived without it.

00:32:32You can find almost everywhere different types

00:32:34of chocolate chip cookies, in ice cream

00:32:36or even in cakes.

00:32:38But this famous cookie only came to life in 1930.

00:32:40The story goes that a woman named

00:32:42Ruth Grave Wakefield

00:32:44prepares chocolate cookies

00:32:46in order to get rid of her guests.

00:32:48Very quickly, she realized

00:32:50that she had no more pastry chocolate,

00:32:52an essential ingredient to prepare

00:32:54classic cookies.

00:32:56To remedy this situation,

00:32:58she bought a half-sweet chocolate tablet

00:33:00thinking that it would end up

00:33:02evenly distributed in the dough

00:33:04given the heat of the oven.

00:33:06Things did not necessarily go

00:33:08as she had planned.

00:33:10But good for her,

00:33:12because that's how she invented

00:33:14even younger than chocolate chip cookies.

00:33:16At least from a historical point of view.

00:33:18There are many stories

00:33:20that try to explain how they were invented.

00:33:22One of them is the following.

00:33:24A chef named George Crum,

00:33:26based in New York,

00:33:28created the chips in 1953.

00:33:30He wanted to try a new cooking method

00:33:32when one of his customers

00:33:34was full of his fries.

00:33:36He said they were too thick

00:33:38and a little soft.

00:33:40Crum then imagined finely chopped potatoes

00:33:42and fries until they were brown.

00:33:44People loved this dish

00:33:46and welcomed this very first

00:33:48batch of chips.

00:33:50Ice cream, anyone?

00:33:52If the story is true,

00:33:54in 1904, at the Universal Exhibition

00:33:56in St. Louis,

00:33:58an ice cream vendor no longer had a cup

00:34:00to serve his specialty.

00:34:02So he made a waffle in the shape of a cone

00:34:04and the rest now belongs to history.

00:34:06Okay, I admit it,

00:34:08similar products to chewing gum

00:34:10were invented in the 18th century.

00:34:12So this discovery is not particularly revolutionary.

00:34:14But the chewing gum we buy today

00:34:16appeared at the end of the 1800s.

00:34:18An American inventor

00:34:20named Thomas Adams

00:34:22wanted to mix different chemical products

00:34:24to create synthetic rubber.

00:34:26He tried, and failed,

00:34:28to exploit the properties of gum

00:34:30for his experiment,

00:34:32but ended up creating this delicious snack.

00:34:34Today, we still use gum

00:34:36to produce a certain number of chewing gums.

00:34:38Jean-Baptiste Jolly

00:34:40worked in the textile industry

00:34:42as a fabric manufacturer.

00:34:44The discovery of the following invention,

00:34:46which we use a lot nowadays,

00:34:48has a little to do with him

00:34:50and more to do with his wife.

00:34:52The story goes that the woman

00:34:54accidentally spilled a kerosene lamp

00:34:56on a tablecloth.

00:34:58Instead of getting angry

00:35:00when seeing the damaged fabric,

00:35:02Jolly noticed that the substance

00:35:04had actually cleaned the fabric.

00:35:06A very clean accident,

00:35:08if I may say so.

00:35:10Now, I love this one.

00:35:12Did you know that kerosene lamps

00:35:14were originally called friction lights?

00:35:16That's the name their inventor,

00:35:18a chemist named John Walker,

00:35:20gave them in 1826.

00:35:22One day,

00:35:24he scratched a chemical product

00:35:26on his chimney by pure chance

00:35:28and realized that it was igniting

00:35:30and creating sparks.

00:35:32Originally made of cardboard,

00:35:34it was then made of wood

00:35:36and glass.

00:35:38In the 1940s,

00:35:40a man named Harry Coover

00:35:42came across a chemical formula

00:35:44that seemed to adhere to everything

00:35:46it touched.

00:35:48The scientific community

00:35:50didn't think much about it

00:35:52because the formula didn't seem

00:35:54to have much application at the time.

00:35:56It was only in 1951 that he

00:35:58thought a little more about the formula

00:36:00and decided to reuse it

00:36:02They used a complete name,

00:36:04adhesive composition based on

00:36:06cyanacrylate, methyl,

00:36:08but you must know it as superglue.

00:36:10It is so used in security

00:36:12these days that it's hard to believe

00:36:14that we didn't invent it on purpose.

00:36:16In 1903,

00:36:18a scientist named Edward Benedictus

00:36:20dropped a bottle by accident.

00:36:22Looking at it from the ground,

00:36:24he was amazed to see that the bottle

00:36:26had slightly melted but retained its shape.

00:36:28He expected it to break

00:36:30into a thousand pieces.

00:36:32Intrigued by this unknown peculiarity,

00:36:34he thought about it

00:36:36and discovered that what kept the glass in place

00:36:38was a substance, cellulose nitrate,

00:36:40that covered the inside of the glass.

00:36:42This is how humanity discovered

00:36:44the glass of security.

00:36:46It's probably not what you imagine

00:36:48when you think of cashew nuts,

00:36:50but a Reddit member found them

00:36:52like this in a store in Brazil.

00:36:54In fact, they are not real nuts.

00:36:56Cashew nuts emerge

00:36:58at the end of a cashew apple.

00:37:00There is a special word

00:37:02for a fruit with a seed inside,

00:37:04a drop.

00:37:06So cashew nuts are drops,

00:37:08just like almonds and pistachios.

00:37:10Brazil is the country of cashew nuts.

00:37:12The tree was then brought to India

00:37:14by the Portuguese

00:37:16in the middle of the 16th century.

00:37:18From there, it spread to Asia

00:37:20and then to West Africa.

00:37:22Today, these regions are the largest

00:37:24cashew nut producers,

00:37:26they import 90%

00:37:28of the world's crops.

00:37:30Speaking of food,

00:37:32here are some interesting facts.

00:37:34Did you know that pineapples

00:37:36grow this way?

00:37:38In addition, they are not part of

00:37:40these fast-growing fruits.

00:37:42It takes them between 16 and 24 months

00:37:44before they can be harvested.

00:37:46Not to mention that a plant can only

00:37:48produce 3 pineapples at most

00:37:50during its life.

00:37:52Fun fact, each pineapple segment

00:37:54has its own flower.

00:37:56Have you ever wondered

00:37:58why the eggplants are called

00:38:00eggplants in English?

00:38:02If you have never seen

00:38:04a growing eggplant,

00:38:06here is a picture.

00:38:08Now you understand.

00:38:10It literally looks like

00:38:12eggs that are growing.

00:38:14In addition, eggplants are not

00:38:16botanical vegetables.

00:38:18They are berries,

00:38:20just like watermelons.

00:38:22You will never guess what it is.

00:38:24It looks like a bouquet of flowers,

00:38:26but it is broccoli that has not been harvested.

00:38:28These flowers are actually edible.

00:38:30Broccoli has been known

00:38:32for at least 2,000 years.

00:38:34It was the Romans' favorite food.

00:38:36But it only appeared in North America

00:38:38in the 1920s.

00:38:40These are Italian immigrants

00:38:42who brought it to California

00:38:44and started selling it.

00:38:46Today, the United States is the third

00:38:48largest producer of broccoli

00:38:50And here is what becomes

00:38:52an artichoke if you let it bloom.

00:38:54An artichoke is actually a flower

00:38:56that has not had time to bloom.

00:38:58It is also one of the oldest

00:39:00foods that humans know.

00:39:02Do you remember that a pineapple

00:39:04takes about two years to produce fruits

00:39:06and that a plant can only carry

00:39:08three pineapples in its life?

00:39:10Well, an artichoke plant can grow

00:39:12up to 20 artichokes per year.

00:39:14Artichoke is one of the healthiest

00:39:16vegetables in terms of antioxidants.

00:39:18Here is a picture of a sleeping turtle.

00:39:20Many of them sleep inside their carapace

00:39:22to protect themselves from predators.

00:39:24But some turtles cannot

00:39:26retract in their carapace,

00:39:28so they sleep in positions similar

00:39:30to this one.

00:39:32These animals are active during the day

00:39:34and sleep at night.

00:39:36The amount of sleep a turtle needs

00:39:38depends on the species.

00:39:40It can go from 10 hours to one.

00:39:42On average, a turtle takes a nap

00:39:44from 4 to 6 hours.

00:39:46The most important factor

00:39:48for a turtle when it goes to sleep

00:39:50is to find a safe place.

00:39:52They can hide under leaves

00:39:54or in holes in the ground.

00:39:56Have you ever seen a chameleon's feet?

00:39:58These creatures have two toes

00:40:00on the inside of the foot

00:40:02and three on the outside

00:40:04at the level of the front feet.

00:40:06And it's the opposite for the back feet.

00:40:08Chameleons live on trees

00:40:10and their feet help them climb better.

00:40:12We all know the unique ability

00:40:14of chameleons to camouflage.

00:40:16In fact, the color depends

00:40:18on the chameleon's mood,

00:40:20temperature, humidity

00:40:22and light.

00:40:24And did you know that some of them

00:40:26have a tongue twice as long

00:40:28as their body?

00:40:30Have you ever seen a walnut's mouth up close?

00:40:32They have teeth inside their beaks.

00:40:34Walnuts are very loyal creatures.

00:40:36It's not a myth that a bird

00:40:38attaches to the first stimulus

00:40:40it sees after an explosion.

00:40:42It doesn't matter if it's a walnut,

00:40:44a person or even a simple object.

00:40:46It will remain devoted to this creature

00:40:48or to this lucky thing

00:40:50throughout its life.

00:40:52Walnuts also mate for life

00:40:54and they are very protective of their offspring.

00:40:56If they lose a loved one,

00:40:58they cry for it.

00:41:00If a walnut from a group gets sick or injured,

00:41:02two or three stay with it

00:41:04to protect and care for it.

00:41:06This adorable little creature

00:41:08is a newborn alligator

00:41:10but don't be fooled by its cute appearance.

00:41:12This little guy is already about 60 years old.

00:41:14It's not the DNA

00:41:16that determines the sex of an alligator,

00:41:18it's the temperature.

00:41:20If the eggs were laid when it was hot,

00:41:22bad alligators will hatch.

00:41:24If they stay in colder temperatures,

00:41:26there will be a lot of females.

00:41:28After hatching,

00:41:30it takes 10 years for an alligator to become an adult.

00:41:32In general,

00:41:34alligators live about 35 years

00:41:36in nature.

00:41:38Alligators can't live in salt water

00:41:40unlike crocodiles

00:41:42because they don't have special glands

00:41:44to excrete salt from their bodies.

00:41:46Here's a newborn pigeon.

00:41:48You've probably seen thousands of pigeons in your life

00:41:50but probably never a newborn.

00:41:52It's because newborn pigeons

00:41:54stay in the nest for about 6 weeks,

00:41:56which is longer

00:41:58than any other bird.

00:42:00When they come out of the nest,

00:42:02they almost look like adult pigeons.

00:42:04No wonder you've never noticed the difference.

00:42:06In addition,

00:42:08these are probably the first domesticated birds

00:42:10by man,

00:42:12and they are experts in navigation.

00:42:14They can find their way

00:42:16at a distance of 2,000 km,

00:42:18which is more than the distance

00:42:20between New York and Florida.

00:42:22We think that pigeons have an innate sense of direction.

00:42:24In fact, in ancient times,

00:42:26mail was distributed

00:42:28by traveling pigeons.

00:42:30This is the mouth of a cow.

00:42:32These brushes are called papyconics.

00:42:34They help the cow to move

00:42:36the food in its mouth.

00:42:38Cows have a field of vision of 330 degrees,

00:42:40so there are few things

00:42:42that can escape their attention.

00:42:44Do you remember that some turtles

00:42:46need only one hour of sleep a day?

00:42:48Cows sleep even less,

00:42:50about 30 minutes a day,

00:42:52and this time is divided

00:42:54into 6 to 10 short periods

00:42:56of deep sleep.

00:42:58These animals stay in a lying position

00:43:00for about 10 hours a day,

00:43:02and then they move,

00:43:04covering long distances,

00:43:06and they drink about 100 liters of water a day.

00:43:08Can you guess what it is?

00:43:10It's sand that has grown 300 times.

00:43:12Sand is broken rock

00:43:14in micro pieces

00:43:16after being eroded for millions of years.

00:43:18Microbial communities live

00:43:20on each grain of sand.

00:43:22Things can get really tiny in this world.

00:43:24Even if there is a lot of it on Earth,

00:43:26sand remains a precious material.

00:43:28Concrete is made from this material,

00:43:30and some countries,

00:43:32such as the United Arab Emirates

00:43:34and Singapore,

00:43:36have imported tons of sand

00:43:38to expand their territory

00:43:40by creating artificial islands.

00:43:42Apparently, that's what sinuses look like.

00:43:44They are empty spaces

00:43:46in the water of your face,

00:43:48behind the forehead,

00:43:50the nose, the cheekbones,

00:43:52and between the eyes.

00:43:54They are very important

00:43:56because they produce mucus,

00:43:58and sinuses also help to detect tastes.

00:44:00Without this capacity,

00:44:02food would be much less tasty.

00:44:04Here is the inside of a bowling ball.

00:44:06You can see that it is not symmetrical,

00:44:08so the weight is not evenly distributed.

00:44:10This allows the ball

00:44:12to have curved trajectories.

00:44:14Besides, it was known that bowling

00:44:16appeared 5,000 years ago

00:44:18in Ancient Egypt.

00:44:20Yes, it's not a new sport,

00:44:22and it was popular all over the world.

00:44:24But the rules and equipment

00:44:26are different everywhere.

00:44:28The first bowling alley

00:44:30was built only in the 19th century

00:44:32in New York.

00:44:34What is here is a Barbapapa

00:44:36that has been forgotten.

00:44:38Conclusion, do not forget it,

00:44:40otherwise it will shrink

00:44:42as if it had never existed.

00:44:44Barbapapa is composed of only two ingredients,

00:44:46colored sugar and air.

00:44:48So we now know the only ingredient

00:44:50in the world that is,

00:44:52so far, free, air.

00:44:54Barbapapa is thinner than a hair.

00:44:56By the way, December 7th

00:44:58is Barbapapa Day.

00:45:00Mark this day in your calendar

00:45:02for next year.

00:45:04With only two ingredients,

00:45:06this candy does not contain fat.

00:45:08In addition, it was created by a candy maker

00:45:10and a dentist.

00:45:12The holes in some types of cheese

00:45:14are not due to chance.

00:45:16Gruyère, for example,

00:45:18is made by special bacteria

00:45:20that produce carbon dioxide.

00:45:22When CO2 is emitted,

00:45:24it inflates like a chewing gum bubble,

00:45:26leaving tiny craters

00:45:28that are also called cheese eyes.

00:45:30It is then cooled,

00:45:32but the holes remain there.

00:45:34More than 40 billion Oreos are made

00:45:36every year.

00:45:38It is the best-selling industrial biscuit in the world.

00:45:40The geometric drawing

00:45:42stamped on these biscuits

00:45:44has the Nabisco logo,

00:45:46symbol of American quality,

00:45:48surrounding the word Oreo.

00:45:50It was created to create the design

00:45:52of this chocolate biscuit

00:45:54as we know it today in 1952.

00:45:56If you use reusable bottles,

00:45:58you probably know that they

00:46:00sometimes tend to smell bad.

00:46:02Even if you only use them

00:46:04to put ordinary water in them,

00:46:06they still end up smelling.

00:46:08But it is not the water itself

00:46:10that releases this smell.

00:46:12It is the microorganisms it contains.

00:46:14If you drink water in a bottle,

00:46:16the particles of your saliva

00:46:18and bacteria start accumulating in the bottle,

00:46:20which generates this smell.

00:46:22If you choose reusable bottles,

00:46:24make sure to wash them every day

00:46:26to prevent bacteria from accumulating.

00:46:28After washing them,

00:46:30let them dry completely

00:46:32before reusing them.

00:46:34There are not only jeans that are blue.

00:46:36Police uniforms are also blue.

00:46:38The first policemen dressed like this

00:46:40appeared in the 19th century in London.

00:46:42They received this blue uniform

00:46:44to contrast with the red and white uniform

00:46:46already worn by the military.

00:46:48Two decades later,

00:46:50such police forces were adopted

00:46:52in the United States

00:46:54that followed the same model.

00:46:56The uniform is still blue today

00:46:58because this color has proven to be very effective.

00:47:00They blend into a nocturnal environment

00:47:02and police officers can observe

00:47:04what is happening without being noticed.

00:47:06In addition, the spots are not too visible

00:47:08on dark fabrics.

00:47:10And then everyone knows

00:47:12that police officers wear blue

00:47:14but they are only recognized by this one color.

00:47:16So why mess all this up?

00:47:18Baby carrots are tiny

00:47:20and unlike ordinary carrots,

00:47:22they are wet,

00:47:24which is reminiscent of our little human babies.

00:47:26These mini-carrots are not

00:47:28special carrots.

00:47:30They are made from ordinary carrots

00:47:32by removing the skin and outer layers

00:47:34and then rubbing them

00:47:36to make them look prettier.

00:47:38The problem is that they can no longer retain moisture.

00:47:40A normal carrot

00:47:42retains a certain amount of water in it

00:47:44thanks to the layers that imprison it.

00:47:46Once cut,

00:47:48the mini-carrots dry easily.

00:47:50This is why they are generally sold

00:47:52in plastic bags containing a little water.

00:47:54Jeans are provided with metal rivets

00:47:56and have always been.

00:47:58Jacob Davis,

00:48:00the man who made the first pair of jeans,

00:48:02added copper rivets

00:48:04to the places where the pants

00:48:06are most likely to tear,

00:48:08namely the bracket and the pockets,

00:48:10Today, the rivets

00:48:12rather serve a decorative function

00:48:14because they are a traditional feature

00:48:16of blue jeans.

00:48:18Another peculiarity of these pants

00:48:20is the presence of these small pockets

00:48:22which apparently serve nothing.

00:48:24This may be the case today,

00:48:26but years ago, when jeans

00:48:28were particularly fond of cowboys,

00:48:30this small pocket was specially designed

00:48:32to store a watch.

00:48:34In addition, at the time,

00:48:36a jean had only four pockets.

00:48:38This tiny pocket,

00:48:40the watch pocket,

00:48:42two large pockets at the front

00:48:44and one pocket at the back.

00:48:46The headrests of cars

00:48:48are a matter of comfort

00:48:50and removable headrests

00:48:52are a matter of safety.

00:48:54If you remove a headrest,

00:48:56you will see two solid metal bars.

00:48:58If you ever find yourself trapped

00:49:00or trapped in a vehicle,

00:49:02you can use these bars

00:49:04to break the glass and escape.

00:49:06These tiny bloodstains

00:49:08can be caused by the rupture

00:49:10of a small blood vessel in the hen

00:49:12when she laid her egg.

00:49:14Eggs with these bloodstains

00:49:16can be consumed without danger,

00:49:18but they can also be removed

00:49:20if it bothers you.

00:49:22This will not affect the taste of the egg.

00:49:24In the Toblerone logo

00:49:26and its famous mountain,

00:49:28the image of a bear

00:49:30standing on its hind legs

00:49:32and about to devour this yodeler

00:49:34This is explained by the fact

00:49:36that bears were very present

00:49:38on the side of Bern,

00:49:40one of the largest cities in Switzerland,

00:49:42where its founder created

00:49:44the famous triangular chocolate snack.

00:49:46Toblerone is also based

00:49:48on a game of words

00:49:50between the creator's family name

00:49:52Theodore Tobler

00:49:54and the Italian word torone

00:49:56which designates a nougat with honey

00:49:58and almonds.

00:50:00The space located

00:50:02Not only are the nougats better protected

00:50:04in their polystyrene goblets,

00:50:06but they also soften more quickly

00:50:08and in a more uniform way.

00:50:10You probably thought that this hole

00:50:12in the body of the pencils

00:50:14had no reason to be,

00:50:16and yet there is one.

00:50:18It is a ventilation system

00:50:20that allows the ink to flow more easily.

00:50:22In this way, equal air pressure

00:50:24is created inside and outside the pen,

00:50:26which allows the ink to flow

00:50:28easily into the tip.

00:50:30Let's see if the bottles of soy sauce

00:50:32have two beakers.

00:50:34The sauce is very liquid

00:50:36and flows quite quickly from the bottle

00:50:38as soon as it is turned over.

00:50:40Most Asian cuisine lovers

00:50:42will admit that they have spilled it

00:50:44everywhere at least once in their life.

00:50:46This is why, nowadays,

00:50:48restaurants prefer to serve soy sauce

00:50:50in special bottles with two beakers.

00:50:52This design allows you to control

00:50:54the flow of sauce that flows.

00:50:56Just put your finger on a beaker

00:50:58and pour the sauce over it.

00:51:00If you press your finger hard on it,

00:51:02the sauce will automatically stop flowing.

00:51:04And if you take it off,

00:51:06it will flow again.

00:51:08Now, I challenge you to get your fingers

00:51:10in your nose.

00:51:12You probably noticed that the seats

00:51:14of trains and buses were covered

00:51:16with fabric with bizarro patterns.

00:51:18Do you know why?

00:51:20These patterns are used to cover

00:51:22the dirt and stains on the seats.

00:51:24The brighter the color and the more patterns,

00:51:26the darker the stains will be.

00:51:28In addition, these patterns are generally so ugly

00:51:30that no one wants to look at them

00:51:32long enough

00:51:34to reveal anything.

00:51:36So yes, the pattern is there

00:51:38to make you look away

00:51:40and if you look at it,

00:51:42to make it less visible.

00:51:44No bus will ever have a white seat.

00:51:46That's guaranteed.

00:51:48The metal tab of the soda cans

00:51:50can be turned over

00:51:52and it is possible to slip a straw

00:51:54into the space.

00:51:56This tab replaced the pin

00:51:58created in the early 1960s.

00:52:00You remember, don't you?

00:52:02It could be very pointy

00:52:04and easily pose a threat

00:52:06to the people in charge

00:52:08of sorting the garbage.

00:52:10Now, you can insert your straw

00:52:12directly into one of them.

00:52:14This also means that you can

00:52:16produce bubbles at will

00:52:18and make all your friends

00:52:20laugh like a three-year-old.

00:52:22It is also a piece of fabric.

00:52:24If the fabric is used

00:52:26to plug holes,

00:52:28it can also be used

00:52:30to test the effects

00:52:32of various detergents

00:52:34on certain surfaces.

00:52:36It is also practical

00:52:38to test the washing cycles

00:52:40of your machine

00:52:42before using them

00:52:44to wash the whole garment.

00:52:46The mechanical stairs

00:52:48are equipped with these

00:52:50to prevent people

00:52:52from getting stuck

00:52:54near the point

00:52:56where the step meets

00:52:58the edge of the stairs.

00:53:00This brush is a small barrier

00:53:02that prevents this.

00:53:04It also allows you

00:53:06to catch plush toys

00:53:08and prevent other small objects

00:53:10from falling into the interstices.

00:53:12The containers for food

00:53:14that we associate

00:53:16most often with Chinese restaurants

00:53:18can also be used as plates

00:53:20since it is possible to eat

00:53:22directly inside

00:53:24without having to worry

00:53:26about dirtying your dishes.

00:53:28Yes, it's true!

00:53:30They were patented in 1894

00:53:32to transport freshly

00:53:34chopped oysters

00:53:36and were known

00:53:38in the Atlantic Ocean

00:53:40under the name

00:53:42of Oyster Pails.

00:53:44They were then adapted

00:53:46to the style of the time

00:53:48when they were much more valuable.

00:53:50Oysters could be easily

00:53:52twisted to melt new pieces

00:53:54of gold or silver

00:53:56and take advantage of them.

00:53:58These strays were created

00:54:00to make it much easier

00:54:02to distinguish the pieces

00:54:04that had been altered.

00:54:06It is no longer necessary

00:54:08today, but the pieces

00:54:10still have this style.

00:54:12All crackers and some biscuits

00:54:14had to escape

00:54:16so that they wouldn't break.

00:54:18If you didn't prick the dough,

00:54:20the steam would accumulate

00:54:22inside and the final result

00:54:24would have a rather weird shape.

00:54:26Dogs like to turn around

00:54:28before going to sleep

00:54:30because they inherited

00:54:32this behavior from their ancestors.

00:54:34At the time, there were no well-baked baskets

00:54:36for the doggies and most of them

00:54:38had to repel the tall grass

00:54:40to create a small corner

00:54:42where all the animals

00:54:44that could have hidden

00:54:46in the vegetation could escape.

00:54:48Donuts have this ring shape

00:54:50for a similar reason.

00:54:52If there were no holes in the center,

00:54:54the dough would never be well-baked.

00:54:56In addition, they are often associated

00:54:58with the American police

00:55:00because in the 1950s,

00:55:02donut shops were one of the rare

00:55:04places to stay open late at night.

00:55:06It was the ideal place for the police

00:55:08who wanted to nibble a piece

00:55:10of dough.

00:55:12If your jean is blue on the outside

00:55:14and white on the inside,

00:55:16it's because the fabric

00:55:18has been woven in a prudent way.

00:55:20The chain thread is dyed

00:55:22while the strap thread

00:55:24has no color,

00:55:26it is simply white.

00:55:28In this way,

00:55:30the manufacturers reduce

00:55:32the amount of dye

00:55:34necessary for each garment.

00:55:36It's not like they were gold-plated.

00:55:38This is the most effective color

00:55:40to attract attention

00:55:42and alert people.

00:55:44No wonder that many security vests

00:55:46and warning cones

00:55:48are also orange.

00:55:50The stop sign has an eight-sided shape

00:55:52to help drivers recognize it easily

00:55:54even if they see it from behind.

00:55:56And when the signs were not yet reflective,

00:55:58the octagonal shape prevented

00:56:00drivers from confusing the stop sign

00:56:02with any other at night.

00:56:04The rough bands on the sides of the road

00:56:06make the noise and vibrations

00:56:08sound like an alarm clock.

00:56:10There are magnetic locks

00:56:12on the fuel pumps in gas stations

00:56:14in case someone leaves

00:56:16with the gasoline gun

00:56:18still attached to his tank.

00:56:20In this case,

00:56:22the lock automatically detaches the hose.

00:56:24The gasoline forms a rainbow

00:56:26in a puddle of water

00:56:28because it cannot mix with water.

00:56:30It forms a thin membrane on top.

00:56:32When the light reflects on it

00:56:34it becomes a rainbow.

00:56:36The triple handle of a jerry can

00:56:38is there to allow two people

00:56:40to carry it more easily

00:56:42and distribute the liquid evenly.

00:56:44Gasoline cans often have a second hole

00:56:46that must also be opened

00:56:48before pouring the liquid.

00:56:50Air passage will prevent it from overflowing

00:56:52and therefore from wasting it.

00:56:54Most gasoline cans have two holes

00:56:56with caps, one larger and one smaller.

00:56:58You are supposed to open the smallest hole

00:57:00before pouring the liquid

00:57:02This will prevent the liquid from sticking

00:57:04and from spreading on your clothes

00:57:06and on the floor.

00:57:08Another little trick that we often neglect

00:57:10is the tip of the cap of an ointment.

00:57:12Most tubes are usually sealed

00:57:14with a plastic film or aluminum foil

00:57:16and opening it with your nails

00:57:18is not the best idea.

00:57:20The tip on the cap makes it easy

00:57:22to open even the most tightly sealed tube.

00:57:24You can use most screwdrivers

00:57:26with a wrench

00:57:28to create more torque.

00:57:30In this way,

00:57:32you will need to apply

00:57:34much less force than usual.

00:57:36You will also be able to reach

00:57:38difficult areas more easily.

00:57:40Cameras are installed in shops,

00:57:42banks and hospitals to monitor everything.

00:57:44If something happens,

00:57:46you can call the police or the ambulance.

00:57:48The camera helps to resolve a lot of cases.

00:57:50So why aren't there cameras

00:57:52in planes?

00:57:54The crew keeps order in the plane

00:57:56but they can't do anything

00:57:58about it.

00:58:00Besides, there is nowhere to hide in a plane.

00:58:02During the flight,

00:58:04cameras are useless

00:58:06and after the flight,

00:58:08passengers' testimonials

00:58:10work as well as cameras.

00:58:12So if cameras are useless,

00:58:14why spend money on them?

00:58:16Water is very easy to clean

00:58:18because it has triangular molecules

00:58:20made up of an oxygen atom

00:58:22and two hydrogen atoms,

00:58:24hence the H2O.

00:58:26A bit like magnets.

00:58:28That's why water easily attaches to other molecules,

00:58:30including those that make up saline.

00:58:32Many individual houses

00:58:34have triangular roofs

00:58:36because it allows rain,

00:58:38snow and dead leaves to slide on the slope.

00:58:40If all these things piled up

00:58:42on the roof of your house,

00:58:44one day it could collapse.

00:58:46When a storm approaches,

00:58:48the clouds seem to become dark.

00:58:50But it's only an illusion.

00:58:52The thin clouds of a sunny day

00:58:54also diffuse all the colors

00:58:56of the bright spectrum.

00:58:58This makes us perceive the clouds as white.

00:59:00The thicker the clouds are

00:59:02and contain droplets of water,

00:59:04the less they let the light through

00:59:06and the darker they seem.

00:59:08A good handful of doors

00:59:10are made of brass, bronze

00:59:12or some alloys of copper.

00:59:14These metals have an anti-germ effect.

00:59:16Bacteria spread much more slowly on them.

00:59:18They also get rid of the microbes

00:59:20quite quickly, in a few hours.

00:59:22But that doesn't mean

00:59:24you shouldn't wash your hands.

00:59:26Diamonds have symmetrical shapes

00:59:28to show you their brilliance.

00:59:30At first, these precious stones

00:59:32are not so beautiful.

00:59:34They go through several stages of size

00:59:36and then become elegant pieces.

00:59:38Most of these stones have a round shape

00:59:40with slightly pointed corners.

00:59:42It is in this shape that diamonds shine the most.

00:59:44Why are there two holes

00:59:46in an electric socket?

00:59:48The left hole is negatively charged,

00:59:50and the space below is ground.

00:59:52Electricity must flow through the circuit.

00:59:54The current goes through the positive hole,

00:59:56through the charger of your phone,

00:59:58for example,

01:00:00then through the negative hole.

01:00:02Have you ever wondered

01:00:04what your jeans pocket was for?

01:00:06People used to wear

01:00:08buttoned-up watches.

01:00:10Your small pocket was designed for this.

01:00:12Today, no one wears this kind of watch anymore,

01:00:14but the pocket is still there.

01:00:16And you can slip small objects like a ring in it.

01:00:18In London, there are poles

01:00:20that look a bit like lightbulbs,

01:00:22but they don't have bulbs.

01:00:24Their official name is

01:00:26smoking pipes,

01:00:28and they are part of history today.

01:00:30But they were very useful in the 19th century.

01:00:32These hollow poles

01:00:34evacuated the air

01:00:36and bad-smelling explosive gases

01:00:38to avoid, let's say,

01:00:40unwanted consequences.

01:00:42Most kitchen scissors

01:00:44have metallic teeth

01:00:46and are used to break nuts,

01:00:48crab shells and other hard objects.

01:00:50You can also use them to open jars

01:00:52and bottles or to remove grass stems.

01:00:54Leather often looks dull to the eye

01:00:56because it is covered with tiny scratches

01:00:58and scratches.

01:01:00They scatter the light that hits the material.

01:01:02When you put on your shoes

01:01:04with a layer of wax,

01:01:06you fill these tiny crevices.

01:01:08The surface becomes smoother

01:01:10and the light rays bounce more uniformly.

01:01:12This is why leather

01:01:14is so shiny.

01:01:16The overlays are filled with a special fluorescent

01:01:18semi-transparent ink

01:01:20that can shine in low light.

01:01:22Yellow and light green colors are the most popular

01:01:24because they don't prevent you from seeing the text

01:01:26after a photocopy in black and white.

01:01:28Photocopiers perceive the yellow and light green marks

01:01:30as very pale

01:01:32and don't print them.

01:01:34Magnets are made in the shape of horseshoes

01:01:36because it increases the magnetic force.

01:01:38Colors are also important.

01:01:40The blue part indicates the south pole

01:01:42and the red part indicates the north pole.

01:01:44Both poles work simultaneously

01:01:46and increase the attraction force.

01:01:48The 1 cm diameter hole

01:01:50in the doors of an elevator

01:01:52is a lock.

01:01:54If the doors are locked,

01:01:56an operator can manually open them

01:01:58by inserting a special key in the hole.

01:02:00As for the tiny holes

01:02:02in the plane's windscreens,

01:02:04they are there to balance the air pressure.

01:02:06The windscreen is made of three layers.

01:02:08The exterior glass is extremely solid.

01:02:10It can withstand the difference in air pressure

01:02:12during take-off and landing.

01:02:14The interior glass,

01:02:16which is the closest to you,

01:02:18is made of less expensive materials.

01:02:20It avoids any potential damage to the window.

01:02:22The hole itself is in the central glass.

01:02:24It not only balances the pressure

01:02:26but also avoids the window from jamming.

01:02:28The mechanical stairs brushes

01:02:30are there for your safety.

01:02:32They prevent you from getting too close

01:02:34to the edge of the elevator.

01:02:36So your clothes or laces

01:02:38won't get stuck between the steps.

01:02:40You see the sun in yellow or orange

01:02:42because the atmosphere of our planet

01:02:44is full of colors like blue,

01:02:46green and purple.

01:02:48That's also why the sun looks

01:02:50warmer at sunrise and sunset.

01:02:52If you go to a store to buy oranges,

01:02:54you'll probably find them in a red net.

01:02:56It's pure marketing.

01:02:58And this color is not a random choice.

01:03:00When they are wrapped

01:03:02in a red mesh net,

01:03:04the oranges look more orange,

01:03:06more juicy and more attractive.

01:03:08So you are more likely to buy them.

01:03:10Oranges are generally sold

01:03:12in green mesh nets

01:03:14for the same reason.

01:03:16If they were wrapped in red,

01:03:18they would look more orange.

01:03:20Green goes better with yellow

01:03:22and makes the color of the oranges stand out more.

01:03:24Mattress manufacturers

01:03:26produce a limited number of different mattresses

01:03:28and the only way to make them different

01:03:30is to invent a fantasy sewing pattern.

01:03:32Two mattresses from two different companies

01:03:34can be exactly the same quality

01:03:36but cost a different price.

01:03:38Most people will never know

01:03:40and will believe that different patterns

01:03:42indicate a different quality.

01:03:44So when you buy one,

01:03:46don't worry about the pattern.

01:03:48Almost all hotels have white bed sheets.

01:03:50They choose this color specifically

01:03:52to show how high their standards of cleanliness are.

01:03:54The whiter the sheets are,

01:03:56the more high-end the hotel looks.

01:03:58It is much easier to see dirt

01:04:00and stains on white laundry.

01:04:02This is proof that your room has been made.

01:04:04Well, I know it's a bit cold

01:04:06or touched,

01:04:08especially during a cold winter day,

01:04:10but did you know that brass door handles

01:04:12are actually really useful

01:04:14in addition to being elegant and shiny?

01:04:16As it is a copper alloy,

01:04:18brass has antimicrobial properties.

01:04:20This means that it can help

01:04:22eliminate germs and harmful bacteria,

01:04:24sometimes in less than two hours.

01:04:26In very busy places,

01:04:28it is even more useful.

01:04:30But since brass is much more expensive

01:04:32than other metals such as nickel and steel,

01:04:34we no longer see many door handles

01:04:36of this type nowadays.

01:04:38Speaking of beautiful polyvalent objects,

01:04:40most screwdrivers have

01:04:42a very small secret that is unique to them.

01:04:44They can sometimes slip into a key

01:04:46to create more torque

01:04:48during torsion.

01:04:50Not to mention their usefulness

01:04:52when it comes to screws located in difficult places.

01:04:54There is a reason why

01:04:56women's shirt buttons

01:04:58are often left-handed,

01:05:00and this has nothing to do with fashion.

01:05:02This practice dates back to the time

01:05:04when chambermaids helped ladies get dressed,

01:05:06and it was easier for them

01:05:08to accomplish their tasks with this orientation.

01:05:10The fact that the buttons are placed

01:05:12in this way is a sign of wealth.

01:05:14It is therefore easy to imagine

01:05:16why this practice has persisted,

01:05:18even if most people

01:05:20dress themselves nowadays.

01:05:22The next time you receive a package

01:05:24in your mail, take a look at the cutter.

01:05:26Depending on the blade,

01:05:28you will be able to benefit from a small advantage

01:05:30in terms of design.

01:05:32It turns out that these are blades that break.

01:05:34Continuously cutting cardboard

01:05:36can use the sharp edge of the blade.

01:05:38To avoid having to buy

01:05:40a brand new cutter,

01:05:42the upper segment of the next line

01:05:44can break to obtain a new super-sharp.

01:05:46To do this, look at the small hole

01:05:48at the base of the tool,

01:05:50sometimes called the blade breaker.

01:05:52The people who came up with this brilliant invention

01:05:54were inspired by the way

01:05:56the chocolate bars are divided.

01:05:58Wait a minute!

01:06:00Don't throw away this cardboard package right away.

01:06:02It is very likely that you have

01:06:04silica gel bags somewhere

01:06:06at the bottom of the box.

01:06:08As this gel is a drying tool,

01:06:10it absorbs the humidity of its environment

01:06:12so that you can keep these bags

01:06:14for other occasions.

01:06:16If you need to dry your phone

01:06:18or another electrical object,

01:06:20you can place it in a container

01:06:22No need to be a mechanic

01:06:24to know when the tires of a standard car

01:06:26need to be replaced

01:06:28because they are equipped with a well-designed indicator.

01:06:30If you look closer,

01:06:32you will see that the tire bands

01:06:34are made up of a pile of rubber notches.

01:06:36When the marks are equal to the perpendicular bars,

01:06:38this is the sign that you must

01:06:40make an appointment with your local car service

01:06:42because it is very likely

01:06:44that the tires have lost most of their traction

01:06:46and that they are no longer safe

01:06:48for driving.

01:06:50The upper corners of the windshield

01:06:52of a car have textured black dots

01:06:54integrated at the edge of the glass.

01:06:56This detail is not there for design reasons.

01:06:58It is a coated coating,

01:07:00which means that a special type

01:07:02of ceramic paint is added to the glass

01:07:04to protect its sealant

01:07:06from UV rays.

01:07:08It also allows you to conceal

01:07:10and create a more coarse surface

01:07:12for the glue used to put the glass in place.

01:07:14Every time you hit the road,

01:07:16check if there is a small bar

01:07:18under the rearview mirror of your car.

01:07:20I bet you didn't know it was there

01:07:22to help you switch from day vision

01:07:24to night vision.

01:07:26It uses a prismatic glass technology

01:07:28to blur the reflection

01:07:30and reduce the glow of the headlights

01:07:32behind you in traffic.

01:07:34These manual adjustment mirrors

01:07:36were invented in the 1930s,

01:07:38but they became the norm

01:07:40in the 1970s.

01:07:42When you are in the car,

01:07:44take a look at the headrests

01:07:46You probably don't know

01:07:48that they have a hidden function.

01:07:50Of course, they can be adjusted

01:07:52to suit all sizes of passengers

01:07:54so that they benefit from adequate support

01:07:56for their head and neck.

01:07:58The hidden feature

01:08:00is that they are detachable

01:08:02and have very solid metal bars.

01:08:04If you ever get stuck in a car

01:08:06and you have to get out of it quickly,

01:08:08these bars can be very useful

01:08:10to break the windows of the car.

01:08:12So you're driving around

01:08:14in a car that looks more like a joke

01:08:16than a real situation

01:08:18likely to occur.

01:08:20But what happens

01:08:22if you are in such a hurry

01:08:24that you accidentally leave

01:08:26with the gasoline gun

01:08:28still in the tank?

01:08:30Well, the guns were designed

01:08:32to avoid any risk.

01:08:34They are equipped with a separation device

01:08:36that allows the pipe to be detached

01:08:38when removed with enough force.

01:08:40Initially designed in the early 20th century

01:08:42exclusively by basketball players,

01:08:44baskets have quickly become

01:08:46one of the essential elements of fashion,

01:08:48just like jeans and leather jackets.

01:08:50If you look at them closely,

01:08:52you will see that they have

01:08:54two additional holes on the side

01:08:56similar to those of shoe laces.

01:08:58They are made like this

01:09:00not only to provide additional ventilation

01:09:02but also to allow people

01:09:04to be more creative with their laces

01:09:06when they wear their shoes.

01:09:08Admit it, you always thought

01:09:10that baskets are united at one end

01:09:12with the sole purpose of keeping them together

01:09:14until you are ready to start your meal.

01:09:16This may not be quite true.

01:09:18If we look at them more closely,

01:09:20it turns out that these wooden tools

01:09:22have a square-shaped end.

01:09:24The baskets made in this way

01:09:26are from an old Japanese traditional design

01:09:28that makes it easy

01:09:30to break the ends.

01:09:32The separate end can then be used

01:09:34as a support for the baskets

01:09:36to keep them cleaner

01:09:38and to ensure that they can be reused

01:09:40since they will not touch the table

01:09:42or any other surface.

01:09:44Women's bikes have a special design

01:09:46that surprisingly has a historical

01:09:48and fashionable function.

01:09:50The lower frame is largely intended

01:09:52to compensate for the generally smaller size

01:09:54of women compared to that of a normal man.

01:09:56If this is the case for the handlebars

01:09:58and the saddle,

01:10:00the general frame is lower

01:10:02for an additional reason.

01:10:04At the time when women wore long skirts

01:10:06every day, they had to make sure

01:10:08that their clothes would not get stuck in the frame.

01:10:10This is how we designed a bike

01:10:12with a lower frame,

01:10:14perfectly suited to women

01:10:16and their needs of the time.

01:10:18The fact that the toothpaste is multicolored

01:10:20is not only a nice advantage

01:10:22to make dental hygiene more fun.

01:10:24There is a secret explanation

01:10:26related to each of the colors

01:10:28dating back to the 1970s.

01:10:30At that time, people were increasingly

01:10:32interested in their oral dental health

01:10:34and so there were products

01:10:36that could do more than just

01:10:38brush your teeth.

01:10:40A company was the first to do this

01:10:42by adding a mouthwash

01:10:44to its toothpaste,

01:10:46i.e. the blue strip.

01:10:48It then added the red strip

01:10:50intended to contain ingredients

01:10:52that help you take care of your gums.

01:10:54Speaking of toothpaste,

01:10:56check the cap the next time

01:10:58you open a new tube

01:11:00for a little surprise.

01:11:02You can take care of your gums

01:11:04without cutting or damaging your gums.

01:11:06Not to mention that it is more hygienic

01:11:08since you will not be able to transfer

01:11:10germs or other bacteria

01:11:12into the product itself.

01:11:14As for the articles to be placed

01:11:16on the counter of the bathroom,

01:11:18the toothbrushes are equipped

01:11:20with a very practical accessory

01:11:22hidden in the hairs.

01:11:24In addition to giving the toothbrush

01:11:26a cooler look,

01:11:28they also have a practical purpose.

01:11:30In addition to the white hairs,

01:11:32this blue tint is intended to pale

01:11:34to indicate when you should

01:11:36replace your toothbrush.

01:11:38Dentists say that toothbrushes

01:11:40must be replaced every 3 to 4 months,

01:11:42but this gives a good reminder

01:11:44in case of forgetfulness.

01:11:46Do you still like to play with Legos?

01:11:48I do not judge you,

01:11:50it is an excellent hobby for all ages.

01:11:52Note that there is a hole

01:11:54on the top of the Legos' heads.

01:11:56This is a security device

01:11:58designed to prevent

01:12:00a person from swallowing

01:12:02one of these pieces.

01:12:04The presence of a hole

01:12:06inside the Lego head

01:12:08allows the air to flow freely

01:12:10through the piece

01:12:12until it can be removed

01:12:14safely.

01:12:16We are now used to all kinds

01:12:18of modern bulbs,

01:12:20some in tubular form,

01:12:22others in diamond form

01:12:24and others still completely twisted.

01:12:26The original design was useful in itself.

01:12:28It was mainly linked

01:12:30to the fact that the glass bulbs

01:12:32were blown by hand,

01:12:34which gave them this round shape at first.

01:12:36The practical reason was

01:12:38that the filament of the bulb

01:12:40had to be at the same distance

01:12:42from each surface of the glass sphere.

01:12:44The easiest way to achieve this

01:12:46was to make the glass in the shape of a globe.

01:12:48If you ever find yourself

01:12:50stuck in the trunk of your car,

01:12:52stay calm.

01:12:54All cars are supposed to be equipped

01:12:56with an emergency lock

01:12:58that opens the trunk

01:13:00if necessary,

01:13:02which is very unlikely.

01:13:04These locks are so well designed

01:13:06that they can be opened by anyone

01:13:08and whatever their age.

01:13:10In addition, the handles are designed

01:13:12to be bright in the dark.

01:13:14You can even pull them with your mouth

01:13:16if there is not enough room

01:13:18to use your hands.

01:13:20And this does not matter

01:13:22as long as you do not

01:13:24need to insert the needle

01:13:26directly into the coil.

01:13:28You could lose it

01:13:30without realizing

01:13:32that you could easily prick yourself

01:13:34and hurt your finger.

01:13:36Nowadays, many sewing kits

01:13:38have a place reserved

01:13:40for storing the needles.

01:13:42It is located at the bottom

01:13:44of the wire coil.

01:13:46Just take it out.

01:13:48It is even possible

01:13:50to find a small hole

01:13:52in the plastic part.

01:13:54It is actually a basic ventilation system.

01:13:56It is supposed to allow the ink

01:13:58to reach the tip of the pen easily.

01:14:00OK, I know it is a super common reflex,

01:14:02but it is not really necessary

01:14:04to shake the spice dispensers

01:14:06to get the product out.

01:14:08You do not believe me?

01:14:10You are not the only one.

01:14:12So go get your favorite salt or pepper bottle

01:14:14in your closet.

01:14:16If it has one of these removable plastic caps,

01:14:18it is perfect for this experiment.

01:14:20Instead of shaking the bottle,

01:14:22try to hold it by the plastic cap

01:14:24while it is upside down.

01:14:26Slowly rotate the bottle

01:14:28from one side to the other

01:14:30and you will see that the spice will flow

01:14:32without you having to shake the bottle

01:14:34and mess up your kitchen.

01:14:36In the same order of ideas,

01:14:38most salt dispensers and pepper dispensers

01:14:40have strips at the bottom of the upside-down part.

01:14:42In case the seasoning is stuck inside,

01:14:44place the bottom of the salt dispenser

01:14:46on top of the top of the pepper dispenser

01:14:48and make little circles

01:14:50so that the strips stick to each other.

01:14:52The seasoning should now flow easily

01:14:54without you having to open the bottle.

01:14:56When it is cold,

01:14:58it often happens that you wear

01:15:00so many layers of clothing

01:15:02that you no longer feel the straps

01:15:04of your handbag or backpack on your shoulders.

01:15:06Not to mention the speed with which they slip.

01:15:08Some jackets have an integrated solution

01:15:10to remedy this problem,

01:15:12in the form of a small strap on the shoulder

01:15:14with a hook or button.

01:15:16It is designed to open and close easily

01:15:18so that you can keep

01:15:20your handbag in place permanently.

01:15:22Most of the time,

01:15:24a peeler is only used to remove

01:15:26the skin of potatoes, carrots or cucumbers.

01:15:28But you can also use your vegetable peeler

01:15:30to cut thin slices of onion.

01:15:32Just cut the onion in four vertically

01:15:34and then start slicing it.

01:15:36This can also help

01:15:38to avoid crying with your onion.

01:15:40Most people don't pay attention to this,

01:15:42but if you ever look

01:15:44closer at your toothpaste tube,

01:15:46you will certainly see

01:15:48small colored drawings,

01:15:50whether they are dots or squares.

01:15:52Colors can vary.

01:15:54They can be black, green,

01:15:56red or even blue.

01:15:58These colored dots are actually

01:16:00intended to help the toothpaste assembly machines.

01:16:02They allow you to know

01:16:04where and when these machines

01:16:06have to cut the toothpaste tubes

01:16:08and fold them to pack them.

01:16:10If there is an element

01:16:12that seems a little strange to you,

01:16:14know that it is always there for a good reason.

01:16:16Most manufacturers do not add

01:16:18additional elements to the shoes

01:16:20just for fun.

01:16:22It would be a waste of time and money,

01:16:24you can imagine.

01:16:26On winter shoes, for example,

01:16:28there is often a small loop

01:16:30at the top and at the back.

01:16:32It is there to help you put them on

01:16:34because you can adjust it quickly

01:16:36by pulling on it.

01:16:38Most of these little boots

01:16:40are designed to be worn

01:16:42during the coldest and humidest months.

01:16:44I admit that it has already happened to me

01:16:46at least once to accumulate layers of clothes

01:16:48to avoid having to put everything

01:16:50in my suitcase.

01:16:52But this becomes problematic

01:16:54when it comes to sitting.

01:16:56What do you do with your coat or jacket?

01:16:58The next time you take the plane,

01:17:00look closer at the seat in front of you.

01:17:02The hook that holds the tablet upright

01:17:04can be used as a hook for your jacket.

01:17:06You can use it for meals during the flight.

01:17:08Most mascaras last

01:17:10from 3 to 6 months,

01:17:12depending on the manufacturer.

01:17:14But you can speed up this process

01:17:16if you are not careful.

01:17:18By continuously pumping the mascara brush

01:17:20to try to distribute more product,

01:17:22you fill the tube with air.

01:17:24The mascara then dries much faster

01:17:26and it wears out faster

01:17:28and no longer fulfills its mission as before.

01:17:30There is a simple way to check

01:17:32if your mascara is still good enough

01:17:34If you don't hear a little plop

01:17:36when you take out the brush,

01:17:38you may need to buy a new one.

01:17:40I know we live in the era

01:17:42of Bluetooth connected devices.

01:17:44But for a sound of better quality,

01:17:46it is always recommended

01:17:48to use headphones

01:17:50that connect via audio jacks.

01:17:52Do you remember noticing black stripes

01:17:54on these jacks?

01:17:56They are not there just to hold them

01:17:58when you plug them into your phone

01:18:00or laptop.

01:18:02These strips are designed

01:18:04to protect the wires

01:18:06during sound transmission.

01:18:08Depending on the number of strips,

01:18:10you can guess which end goes where.

01:18:12An empty space under the nozzles

01:18:14does not mean that the company

01:18:16that produced them wanted to scam you

01:18:18by depriving you of a complete portion.

01:18:20No, no.

01:18:22It is a way to protect the nozzles

01:18:24during their transport.

01:18:26It also facilitates the circulation

01:18:28of hot water that is poured

01:18:30through the nozzles.

01:18:32It is designed to meet

01:18:34several objectives.

01:18:36First of all, it is a way

01:18:38to prolong the life of the garment

01:18:40that will keep its shape

01:18:42over the years.

01:18:44It also serves to pass the head

01:18:46through the sweater

01:18:48in case it needs to be pulled.

01:18:50In this way,

01:18:52it ensures a better grip

01:18:54around the neck.

01:18:56Finally, it helps to absorb

01:18:58additional pockets on the right side.

01:19:00It turns out that this pocket

01:19:02was once used by men

01:19:04to easily access their train tickets

01:19:06because most of them went to work

01:19:08every day.

01:19:10It allowed them to keep their buttoned jacket

01:19:12while benefiting from a pocket.

01:19:14Today, it is just a useless decoration.

01:19:16Speaking of things

01:19:18that we no longer use today,

01:19:20or at least not in their initial purpose,

01:19:22did you know that Pledo

01:19:24was originally a cleaning product?

01:19:26In 1920,

01:19:28industrialists needed a product

01:19:30that would help them clean

01:19:32the upholstered area

01:19:34around the coal ovens.

01:19:36The recipe for what we know today

01:19:38under the name of Pledo

01:19:40was thus invented.

01:19:42It was made only in white

01:19:44and was supposed to clean the wallpaper

01:19:46by being rolled back and forth

01:19:48on the dirt.

01:19:50It was only later,

01:19:52in the 1940s,

01:19:54that it became available on the market.

01:19:56Although I still enjoy eating

01:19:58a good piece of toasted bread

01:20:00for breakfast,

01:20:02isn't it boring to have to

01:20:04clean the wallpaper?

01:20:06Well, not anymore,

01:20:08because I recently discovered

01:20:10that wallpapers have a slide

01:20:12or a panel at the bottom

01:20:14that allows you to get rid

01:20:16of all these annoying crumbs.

01:20:18It was a time when video games

01:20:20could only be used by inserting

01:20:22small cartridges.

01:20:24People, especially the youngest,

01:20:26began to go to the hospital

01:20:28after swallowing small game cartridges.

01:20:30Nintendo, the company that makes

01:20:32most of these devices,

01:20:34had to find a creative solution

01:20:36to avoid these accidents.

01:20:38That is why, nowadays,

01:20:40Nintendo Switch cartridges

01:20:42are voluntarily coated with special chemicals

01:20:44that leave a really unpleasant

01:20:46bitter taste in the mouth.

01:20:48Clearly, I do not recommend you

01:20:50The cylinder located

01:20:52at the end of a cable

01:20:54is placed there and seems

01:20:56totally useless.

01:20:58In fact, it is a ferrite pearl

01:21:00that is associated with many electric wires

01:21:02to reduce electromagnetic interference.

01:21:04The electric wires act

01:21:06as involuntary antennas

01:21:08and diffuse the EMIs.

01:21:10There is a reason why the tray

01:21:12that rotates inside the microwave

01:21:14is circular.

01:21:16A circular object evenly distributes heat,

01:21:18unlike rectangular or square objects.

01:21:20When you place containers

01:21:22with these shapes inside,

01:21:24the energy is concentrated on the corners

01:21:26instead of being evenly distributed

01:21:28as in a round container.

01:21:30The temperature gauge

01:21:32of a bread grill

01:21:34is generally used to determine

01:21:36the degree of cooking of the pies.

01:21:38But the other more specific use

01:21:40of the gauge is that of different types of bread.

01:21:42White and sweet bread

01:21:44heat up much faster

01:21:46while brown and rye bread is heavier.

01:21:48The older the bread,

01:21:50the more time it will take

01:21:52to get the golden result you are looking for.

01:21:54Most ovens

01:21:56offer you the possibility

01:21:58to leave the door open

01:22:00when you grill a dish inside.

01:22:02You probably think

01:22:04that the goal is to cool the oven

01:22:06after use.

01:22:08In fact, its goal is to focus

01:22:10on the cooking of the top of the dish

01:22:12and to ensure a crispy layer

01:22:14of heat and steam.

01:22:16By leaving the door slightly open,

01:22:18you get the desired result

01:22:20without cooking the whole dish

01:22:22until it is crispy.

01:22:24You have probably noticed

01:22:26that your dishwasher

01:22:28has specific areas for different types

01:22:30of covers and dishes.

01:22:32But all dishes must be oriented

01:22:34towards the center

01:22:36and not all in the same direction.

01:22:38The types of food on the plates

01:22:40will also determine their location

01:22:42in the oven.

01:22:44When the oven receives the strongest gel,

01:22:46the glucid-based stains

01:22:48from tomatoes and potatoes

01:22:50must be placed here.

01:22:52The detergent is more concentrated

01:22:54on the outside during cleaning,

01:22:56which creates a cascade-shaped cleaning.

01:22:58This is why protein-based stains,

01:23:00such as those of eggs,

01:23:02must be placed here.

01:23:04The ceiling fans push the fresh air

01:23:06down when it is hot,

01:23:08thus making the room circulate.

01:23:10You can do the same thing in winter

01:23:12if you switch the switch on the side

01:23:14or if you use the fan.

01:23:16So if you want to save money

01:23:18on heating and try to quickly

01:23:20heat your room on a cold day,

01:23:22put the fan in motion.

01:23:24It will push the air up

01:23:26and spread the hot air around you,

01:23:28thus heating the room more efficiently.

01:23:30Do you still use post-it notes

01:23:32instead of these new sophisticated applications

01:23:34on all imaginable devices?

01:23:36Welcome to the club!

01:23:38No matter how you use them,

01:23:40they always end up falling.

01:23:42If you have already encountered this problem,

01:23:44it is because you took them off

01:23:46from the bottom to the top.

01:23:48It is this way of doing things

01:23:50that causes the post-it notes.

01:23:52By taking them off on the side,

01:23:54you make sure they stay flat,

01:23:56ready to remind you of your daily tasks.

01:23:58Did you know that post-it notes

01:24:00were invented only 50 years after

01:24:02tin boxes became commonplace?

01:24:04So how was it possible to open

01:24:06a tin box?

01:24:08There are a few alternative methods

01:24:10in case you have missed

01:24:12your faithful post-it note.

01:24:14All you need is a metal spoon.

01:24:16Place the box on the worktop,

01:24:18hold it firmly,

01:24:20and hold the head of the spoon.

01:24:22Press and rub vigorously

01:24:24the edge of the lid of the box

01:24:26on a small surface.

01:24:28It takes time, but by rubbing,

01:24:30a small notch is formed

01:24:32and soon turns into a hole.

01:24:34Once you have passed the tip of the spoon,

01:24:36place the lever on the lid

01:24:38and continue to stretch the edges

01:24:40until you can finally access

01:24:42the meal it contains.

01:24:44You have won!

01:24:46Most toilets depend on

01:24:48the pressure of the water

01:24:50and the gravity to function.

01:24:52A power failure will not affect them.

01:24:54But if yours need electricity

01:24:56to function, you should worry

01:24:58about their use in case of a power failure.

01:25:00The good news is that electricity

01:25:02can be used to fill the toilets

01:25:04and not to draw water.

01:25:06As the mechanism of water drawing

01:25:08always works, open the toilet tank,

01:25:10pour a few liters,

01:25:12and you will be able to evacuate

01:25:14everything you need.

01:25:16The plugs in the shower channels

01:25:18occur over a long period.

01:25:20It is inevitable.

01:25:22We lose 50 to 100 hairs a day

01:25:24and many of them seek to settle

01:25:26in our shower channels.

01:25:28The hair is the main basis

01:25:30of many other things.

01:25:32A good trick is to use your vacuum

01:25:34and to put the tip in the hole

01:25:36after removing the grid.

01:25:38Use a damp cloth around the tip

01:25:40making sure that the air

01:25:42cannot escape.

01:25:44The vacuum will be able to vacuum

01:25:46things that obstruct much more easily.

01:25:48You will avoid the costs of plumbers

01:25:50who use this technique themselves.

01:25:52To make your candles last longer,

01:25:54cut their wick several times

01:25:56and keep them as far as possible

01:25:58from water and moisture.

01:26:00This will ensure that the wax

01:26:02of your candle remains firm and stable

01:26:04and that it continues to burn

01:26:06more slowly for a longer period.

01:26:08The empty space between the windows

01:26:10of the oven door is there for a good reason.

01:26:12You can slide a brush

01:26:14to clean the window of the oven door.

01:26:16It is easy to access this space

01:26:18through the bottom of the door.

01:26:20Open the lower part,

01:26:22then push the brush into the hole.

01:26:24When you park in a garage,

01:26:26you need to determine

01:26:28how far you should be.

01:26:30All cars are not equipped

01:26:32with sensors that guarantee

01:26:34that you keep the right distance

01:26:36before the bumper

01:26:38makes a notch on the wall.

01:26:40Stretching a rope

01:26:42with a tennis ball

01:26:44from the ceiling

01:26:46at the right distance

01:26:48will help you learn

01:26:50the best distance to respect

01:26:52to park in relation to the wall.

01:26:54In case you don't have one,

01:26:56an excellent alternative

01:26:58is to draw along the edges of the key

01:27:00with a gray pencil,

01:27:02then insert it into the lock.

01:27:04Continue until the hole

01:27:06in the lock is sufficiently lubricated

01:27:08and the key works without problems.

01:27:10Clamps are likely to damage

01:27:12the taps and shower heads

01:27:14when you use them to repair them

01:27:16and they are also difficult to grab.

01:27:18Take two pieces of the end

01:27:20of an old watering pipe

01:27:22and attach it to the jaw of the clamp.

01:27:24You will see a huge improvement

01:27:26in grip and you will avoid

01:27:28the risk of wear.

01:27:30You can find a good use

01:27:32of used rubber for different things

01:27:34in the house.

01:27:36When you have enough to tighten

01:27:38or loosen a screw with a screwdriver,

01:27:40try using a simple rubber,

01:27:42placing a part in the handle of the screwdriver

01:27:44and it will have a much better grip.

01:27:46Moving cement blocks

01:27:48is not safe for the lower back.

01:27:50Even with a wheelbarrow,

01:27:52it can be risky to drop the cement

01:27:54on the ground without causing damage.

01:27:56Three simple cylinder-shaped pipes

01:27:58can make all the difference,

01:28:00regardless of the size of the block.

01:28:02Try to lift the edge of the first pipe

01:28:04with a lever,

01:28:06then push and maneuver it

01:28:08by gradually directing the three pipes

01:28:10to the desired place.

01:28:12Just make sure you don't do it in a slope.

01:28:14The first time you hit a nail

01:28:16can be a great success

01:28:18if you have a really sharp thumb.

01:28:20A hair clip has the perfect shape

01:28:22to hold the nail in place,

01:28:24which allows your hand to be safe

01:28:26and to hit the nail without fear.

01:28:28Use a pencil instead of a pen

01:28:30or a pencil when you work

01:28:32with a water-circular saw

01:28:34to make sure the marks are not erased.

01:28:36They will also be easier to see

01:28:38under the water.

01:28:40Checking the pipes on the roof

01:28:42and determining when they need to be cleaned

01:28:44can take a lot of time.

01:28:46Use tape to attach a mirror

01:28:48to the end of a long broom

01:28:50and check whether the pipes

01:28:52need to be cleaned.

01:28:54To help you keep your balance

01:28:56when examining the pipes,

01:28:58attach a pair of old sports shoes

01:29:00to the foot of the ladder.

01:29:02The distance between the shoe and its grip

01:29:04will ensure an additional level of safety.

01:29:06Liquid quenching products

01:29:08are usually in the form of huge tubes

01:29:10so that you can never use them

01:29:12all at once.

01:29:14The hardened tip of the liquid

01:29:16creates nozzles.

01:29:18Take a used lye nozzle

01:29:20and drill it to make a perfect lid

01:29:22that covers the liquid quench.

01:29:24It is now ready to be used again

01:29:26without any blocking.

01:29:28Passenger seat seat belts

01:29:30have a fabric loop.

01:29:32When it is subjected to high pressure,

01:29:34the loop tightens

01:29:36and the excess fabric can cushion the passengers.

01:29:38These few extra centimetres

01:29:40can make a big difference

01:29:42but it is different

01:29:44for the driver.

01:29:46As the seat belt is close to the steering wheel,

01:29:48it is safer for him

01:29:50not to have this loop.

01:29:52Seat belts were invented

01:29:54in the middle of the 19th century

01:29:56but they only began to be used

01:29:58in the 1960s.

01:30:00Pre-collision sensors

01:30:02have made the safety devices

01:30:04go to a higher level.

01:30:06By predicting the collision

01:30:08of a car effectively,

01:30:10this technology allows the seat belt

01:30:12to tighten automatically,

01:30:14to open the airbags

01:30:16and to activate the brakes to reduce the impact.

01:30:18Every year,

01:30:206 million car accidents

01:30:22occur in the United States.

01:30:24This is why we must continue

01:30:26to develop safety devices

01:30:28not only to mitigate accidents

01:30:30but also to protect passengers

01:30:32more effectively.

01:30:34The materials that make up the body

01:30:36began to be replaced

01:30:38in the last 25 years

01:30:40by aluminium and magnesium alloys

01:30:42to carbon fibre composites.

01:30:44These lighter materials

01:30:46not only save fuel

01:30:48but also guarantee

01:30:50that the body offers a deformation zone.

01:30:54When a car hits an object,

01:30:56this zone absorbs the impact energy.

01:30:58But if this seems to cause

01:31:00more damage to the car,

01:31:02it actually protects the passengers better.

01:31:04The bumpers

01:31:06are largely underestimated

01:31:08and since we have been using them,

01:31:10it would be hard to imagine

01:31:12without them.

01:31:14The bumpers were invented

01:31:16at the end of the 1800s.

01:31:18They have evolved so much

01:31:20that we no longer realize

01:31:22that we have them.

01:31:24But they are there,

01:31:26hidden under the exterior coatings,

01:31:28made up of foam or compressible plastic

01:31:30surrounding a reinforced bar.

01:31:32All the windows of your car

01:31:34are designed to be impenetrable.

01:31:36It is leathered

01:31:38so that whatever the impact,

01:31:40no glass shards are projected

01:31:42on the front seats.

01:31:44Normal glass was used

01:31:46until the 1950s.

01:31:48As vehicles evolved,

01:31:50modifications were made

01:31:52to ensure more safety.

01:31:54Airbags now seem to have always existed.

01:31:56In fact, they were invented

01:31:58in 1968

01:32:00and were ahead of their time.

01:32:02They then slowly gained popularity

01:32:04and eventually became

01:32:06mandatory on all cars

01:32:08from 1998.

01:32:12They have also evolved

01:32:14and are no longer limited

01:32:16to a simple airbag in the steering wheel.

01:32:18Today, you can find them

01:32:20everywhere in the car

01:32:22to ensure the safety

01:32:24of all passengers.

01:32:26Collision sensors

01:32:28connected to an on-board computer

01:32:30detect and trigger the airbags

01:32:32which inflate in a few milliseconds.

01:32:36It can be difficult

01:32:38to anticipate weather and road conditions.

01:32:40At the end of the 1960s,

01:32:42the ABS anti-skid system

01:32:44was put in place on cars.

01:32:48Before that, it was used

01:32:50on many aircraft,

01:32:52whose design dates back to 1908.

01:32:54It quickly became necessary

01:32:56on all vehicles,

01:32:58to ensure better grip

01:33:00on slippery surfaces

01:33:02and better control of the wheels

01:33:04during braking.

01:33:06Today, the ABS has advanced

01:33:08so much that the latest versions

01:33:10provide additional detection

01:33:12in the event of strong lateral winds.

01:33:14The speed regulator,

01:33:16invented in 1948,

01:33:18has not stopped evolving

01:33:20over the years.

01:33:22Today, the adaptive speed regulator

01:33:24means that when the car

01:33:26changes direction,

01:33:28it adapts its speed to that of the previous one.

01:33:30Other variants make sure

01:33:32that the car stops on its own

01:33:34if the vehicle in front of it does the same.

01:33:38It is easy to forget

01:33:40to turn on the lights

01:33:42when driving for several hours.

01:33:44Automatic lights

01:33:46are becoming more and more common.

01:33:48Cameras determine the type of light

01:33:50in real time

01:33:52and help determine

01:33:54whether the lights are on or off.

01:33:56Although automatic lights

01:33:58have existed since the 1950s,

01:34:00the old models used sensors

01:34:02sensitive to light

01:34:04and were much less reliable.

01:34:06The new models can identify

01:34:08different sources of light,

01:34:10whether it is the sun,

01:34:12the direct light of a car

01:34:14coming in front of it,

01:34:16or even the reflection of a panel,

01:34:18which makes it possible

01:34:20to adapt the lights

01:34:22that cause about 400,000 accidents

01:34:24per year in the United States.

01:34:26The solar sensors

01:34:28located in the rear bumper

01:34:30and the blind spot monitoring systems

01:34:32monitor the adjacent lanes.

01:34:34They alert the driver

01:34:36if a vehicle is on the lane next to it,

01:34:38whether by lights

01:34:40flashing on the dashboard

01:34:42or by beeps

01:34:44reducing the danger.

01:34:481.6 million road accidents

01:34:50are caused by using the phone

01:34:52while driving,

01:34:54and fatigue is at least 10%

01:34:56of car accidents.

01:34:58The driver's attention

01:35:00monitoring system

01:35:02controls all this.

01:35:04It works with sensors

01:35:06that monitor the movements

01:35:08of the car and the number

01:35:10of steering corrections

01:35:12to make sure the driver

01:35:14stays alert.

01:35:16When the on-board computer

01:35:18detects an accident,

01:35:20it alerts the driver

01:35:22and tells him

01:35:24what to do.

01:35:26Tires are one of the most critical

01:35:28parts of your car

01:35:30and are closely linked

01:35:32to the type of road you drive.

01:35:34Many safety devices

01:35:36depend on them.

01:35:38That's why it's very important

01:35:40to make sure your tires

01:35:42are always in perfect condition.

01:35:44The tire pressure monitoring system

01:35:46and the constant evolution

01:35:48of technology ensure

01:35:50you're safe on long journeys.

01:35:52The white line crossing sensors

01:35:54focus on the ground markings

01:35:56and make sure the car

01:35:58stays on its path.

01:36:00If it deviates and approaches

01:36:02a non-flashing line,

01:36:04a camera identifies it

01:36:06and signals it to the driver.

01:36:08The lane assist function

01:36:10follows the same method

01:36:12to prevent the car

01:36:14from changing lanes.

01:36:16It automatically adjusts the steering

01:36:18to focus the car on its path.

01:36:20Even the most modern cars

01:36:22have autonomous driving options.

01:36:24Automatic driving systems

01:36:26move the speed regulator

01:36:28to a higher level

01:36:30so the car stays on its path

01:36:32while maintaining speed

01:36:34and changing lanes

01:36:36when necessary.

01:36:38Some devices are progressively

01:36:40used in all car models.

01:36:42For example, the night vision system

01:36:44uses thermographic cameras

01:36:46to locate pedestrians and animals.

01:36:48It integrates with the on-board computer

01:36:50and identifies objects

01:36:52based on their thermal signatures.

01:36:54There are more than 1.4 billion

01:36:56cars in traffic around the world.

01:36:58And as the world population

01:37:00increases, we expect

01:37:02more cars to do the same.

01:37:04Safety systems

01:37:06are constantly evolving.

01:37:08Infrared headlights

01:37:10will soon be used

01:37:12in bad visibility conditions

01:37:14such as storms, snow and fog.

01:37:16They will improve

01:37:18the driver's visibility

01:37:20in all conditions

01:37:22without affecting the other drivers' vision.

01:37:24The driver's control systems

01:37:26will soon be able to monitor

01:37:28and identify these different behaviors.

01:37:30Whether during careless driving

01:37:32or for other safety reasons,

01:37:34cars will soon be able

01:37:36to take control themselves

01:37:38thus ensuring the safety

01:37:40of all passengers.

01:37:42The augmented reality

01:37:44headlamps, which are being developed,

01:37:46allow certain elements

01:37:48of the dashboard to be displayed

01:37:50on the headlamp.

01:37:52So soon, all the most useful

01:37:54indications will appear

01:37:56right in front of the driver

01:37:58so that they no longer

01:38:00get out of sight.

01:38:02Airbags will no longer

01:38:04only be used inside the car,

01:38:06because they will identify

01:38:08an imminent collision.

01:38:10They will cover the entire surface

01:38:12of the car to reduce the impact.

01:38:14This technology could be so advanced

01:38:16that the body would no longer

01:38:18need to be repaired.

01:38:20Future technologies should be

01:38:22so advanced that cars themselves

01:38:24will have their own forms of communication.

01:38:26Not with drivers,

01:38:28but with other cars.

01:38:30Imagine cars sharing

01:38:32information when they identify

01:38:34roadblocks, road problems

01:38:36or certain weather phenomena.

01:38:38All this will guarantee

01:38:40the most efficient route

01:38:42and a safer journey.

01:38:44It's your birthday today.

01:38:46You make a wish

01:38:48and blow out the candles.

01:38:50You have to cut this delicious round cake now.

01:38:52The guests can't wait to taste it.

01:38:54Wait a second.

01:38:56Are you sure you know how to cut it?

01:38:58As usual,

01:39:00people cut slices

01:39:02in the shape of a V.

01:39:04This method is the best known,

01:39:06but it is far from perfect.

01:39:08Some guests will have

01:39:10a slice without icing,

01:39:12while others will have a lot.

01:39:14In addition, a cake is quite fragile,

01:39:16so you risk putting crumbs everywhere.

01:39:18This technique has become viral

01:39:20because it is downright practical.

01:39:22All you have to do

01:39:24is press a cutting board

01:39:26very gently on the cake.

01:39:28Now you have to cut the cake

01:39:30to the right thickness

01:39:32and place the bottom

01:39:34on the cutting board.

01:39:36You can now cut this large piece

01:39:38into small pieces

01:39:40for your guests.

01:39:42Everyone will be able to eat

01:39:44the amount of cake they want.

01:39:46But no one wants small pieces in general.

01:39:48The leftovers

01:39:50will also be able to be kept longer.

01:39:52If someone still wants cake,

01:39:54just repeat the operation.

01:39:56If the cake is too small,

01:39:58compared to the number of guests,

01:40:00here is a little tip

01:40:02for everyone to be served.

01:40:04Cut the cake into small cubes

01:40:06and mix them

01:40:08in small paper ramekins.

01:40:10Then just put a toothpick

01:40:12in each part

01:40:14so that it does not fall apart.

01:40:16And there you go!

01:40:18You can serve this cake

01:40:20on a plate.

01:40:22If you don't have a knife

01:40:24to cut your cake,

01:40:26you can use a toothpick.

01:40:28The toothpick cuts perfectly

01:40:30the pieces and maintains

01:40:32all the decoration

01:40:34and the icing in perfect condition.

01:40:36It is a method that also works

01:40:38perfectly to cut cakes

01:40:40or cakes in thickness.

01:40:42Of course, it is better to use

01:40:44neutral toothpick

01:40:46if you want to avoid

01:40:48getting cake pieces

01:40:50that taste like mint.

01:40:52You hang boards

01:40:54with nails to fix frames

01:40:56that have a hanging wire at the back.

01:40:58There is a good chance

01:41:00that these frames are not straight.

01:41:02The best is to put two nails.

01:41:04Your boards will finally be straight.

01:41:06You also have to make sure

01:41:08that the hanging wire

01:41:10of the board is not too long.

01:41:12If it is too long,

01:41:14a space will be created

01:41:16between the top of the frame

01:41:18and the wall.

01:41:20You can also use

01:41:22even the best quality markers

01:41:24to stop working one day.

01:41:26This is not a reason to say goodbye to them.

01:41:28Glue them around a flower pot

01:41:30and paint everything with a golden bomb.

01:41:32Result,

01:41:34a glamorous vase to decorate your living room.

01:41:36This project also works

01:41:38with any other vase

01:41:40or tin box

01:41:42as long as they are the same size

01:41:44as your markers.

01:41:46Have you ever put coffee

01:41:48all over your clothes

01:41:50or at the office

01:41:52from the cafeteria?

01:41:54Most people hold their cups

01:41:56with both hands

01:41:58or by spear.

01:42:00These methods

01:42:02have the risk of burning.

01:42:04Recent studies have shown

01:42:06that it was the best way

01:42:08to hold your cup

01:42:10to prevent the liquid

01:42:12from overflowing.

01:42:14I bet you don't do that

01:42:16as usual.

01:42:18In case

01:42:20you didn't know,

01:42:22there are small tabs

01:42:24on the sides of your tin box.

01:42:26If you push them inside,

01:42:28they will hold the roller

01:42:30in place while you unroll it

01:42:32effortlessly.

01:42:34In some shoe stores,

01:42:36shoes are sold with a little belt.

01:42:38Wait, don't throw it away.

01:42:40It's useful.

01:42:42If you ever wet your shoes,

01:42:44you can put them to dry on the radiator

01:42:46with this little belt.

01:42:48They will dry quickly and evenly.

01:42:50It's particularly useful

01:42:52if you wet your shoes

01:42:54when you go to work.

01:42:56If you like to wash and dry

01:42:58your shoes at the machine

01:43:00so that they are perfectly clean,

01:43:02you know that it can make

01:43:04quite a lot of noise.

01:43:06To avoid this rock noise

01:43:08in the drum,

01:43:10put your shoes with their laces

01:43:12in a linen bag.

01:43:14If you put a towel in the machine,

01:43:16it will rub your shoes

01:43:18during washing

01:43:20and they will be even cleaner.

01:43:22Just be careful

01:43:24not to use the towel

01:43:26in the bathroom afterwards.

01:43:28The glass cleaner

01:43:30is a very useful ingredient

01:43:32in case of emergency

01:43:34to put your leather shoes

01:43:36back in place.

01:43:38Just put a little on the shoe

01:43:40and rub it with a piece

01:43:42of cloth.

01:43:44Don't panic,

01:43:46fill your shoes with the cloth

01:43:48to give them their original shape.

01:43:50Then just put a wet towel

01:43:52on the laces

01:43:54and gently vaporize them

01:43:56with the steam of the iron.

01:43:58The laces will be less visible

01:44:00or completely disappear.

01:44:02Here is a genius tip

01:44:04to preserve and serve aromatic herbs.

01:44:06Cut and mix several types

01:44:08of aromatic herbs.

01:44:10Be careful not to cut everything

01:44:12every time you cook.

01:44:14You can also make a great seasoning

01:44:16for your salad.

01:44:18Just add oil, spices

01:44:20and sauce directly into the bottle

01:44:22and shake it well

01:44:24to mix all the ingredients.

01:44:26When you heat a dish in the microwave,

01:44:28part of the food becomes hot

01:44:30while the rest is still frozen.

01:44:32You may have already tried several tips

01:44:34to solve this problem,

01:44:36but here is the classic tip.

01:44:38Put a plate in the middle

01:44:40to get a donut shape.

01:44:42In this way,

01:44:44the microwave will heat more evenly.

01:44:46Don't put your plate in the center

01:44:48of the microwave tray.

01:44:50It's better to leave it on the outside.

01:44:52It will heat better.

01:44:54If you have to heat two dishes at the same time,

01:44:56just put a clean cup upside down

01:44:58in the microwave

01:45:00and put the second dish on it.

01:45:02That's it, it's simple

01:45:04and it saves time.

01:45:06Cut the lemon in half

01:45:08and put one of the two halves

01:45:10in the tweezers.

01:45:12Now just press the tweezers

01:45:14on top of a bowl.

01:45:16Add a little water, sugar

01:45:18and here is a delicious lemonade.

01:45:20Prepare your popcorn in the microwave

01:45:22before watching the last episode

01:45:24of your favorite series.

01:45:26Even after 1 or 2 minutes of cooking

01:45:28in the microwave,

01:45:30there are still hard grains

01:45:32at the bottom of the bag.

01:45:34Fortunately,

01:45:36there is a notch at the bottom of the bag.

01:45:38Here's what you're supposed to do.

01:45:40When your popcorn is ready,

01:45:42don't open the bag right away.

01:45:44Turn the bag over

01:45:46and shake it vigorously over a bowl.

01:45:48All the grains that haven't exploded

01:45:50will fall.

01:45:52Now you can enjoy your donut without danger.

01:45:54If by chance you burn food

01:45:56on your plates

01:45:58and you want to prevent fire detectors

01:46:00from turning on,

01:46:02you can do this.

01:46:04One of the best ways to get rid

01:46:06of the smoke quickly

01:46:08is to use a half-wet towel.

01:46:10By holding the towel on the dry side,

01:46:12turn it over your head.

01:46:14The wet side will quickly absorb

01:46:16the solid particles of the smoke.

01:46:18No need for a knife to peel a kiwi.

01:46:20Just remove the top

01:46:22and the bottom

01:46:24and insert a spoon into the kiwi

01:46:26to separate the fruit from the skin.

01:46:28There you go, a peeled kiwi.

01:46:30Some people, however, prefer

01:46:32to eat the kiwi directly with the skin.

01:46:34It is perfectly edible

01:46:36and very rich in fiber,

01:46:38folic acid and antioxidants.

01:46:40If the hairy side doesn't bother you,

01:46:42enjoy it.

01:46:44But don't forget to wash

01:46:46your kiwis before eating them.

01:46:50Crackers are holes

01:46:52to prevent them from cracking

01:46:54and breaking during cooking.

01:46:56Without these holes,

01:46:58you can't break them.

01:47:00If you look at the capsule

01:47:02of a soda bottle,

01:47:04you'll notice a plastic disc inside.

01:47:06It seals the liquid and the gas

01:47:08so that the drink stays sparkling.

01:47:10The long neck of the bottle

01:47:12is designed to keep it in place.

01:47:14This way, the heat from your hand

01:47:16will only heat up this part of the bottle

01:47:18instead of making the whole bottle warm.

01:47:20It's hard to see the dishes

01:47:22when they're in the microwave

01:47:24because of this black stain

01:47:26on the glass.

01:47:28But if it's there,

01:47:30it's to prevent harmful waves

01:47:32from escaping.

01:47:34It acts like a shield

01:47:36to protect you

01:47:38while ensuring adequate cooking.

01:47:40Some products, like chips,

01:47:42contain up to 43% nitrogen.

01:47:44You might think

01:47:46you're being sold a bag

01:47:48half-filled with air,

01:47:50but it's quite the opposite.

01:47:52The oxygen, the gas we breathe

01:47:54and the air we breathe

01:47:56all contain nitrogen.

01:47:58This phenomenon, called oxidation,

01:48:00is well-known.

01:48:02Nitrogen, on the other hand,

01:48:04is an inert gas that keeps food

01:48:06and prevents it from getting damaged

01:48:08during transport.

01:48:10Chips wrapped in an air cushion

01:48:12remain crispy

01:48:14and don't risk turning into crumbs.

01:48:16Donuts are hollowed out

01:48:18so that the outside and the inside

01:48:20cook evenly.

01:48:22Marks on paper

01:48:24are not used to write dates

01:48:26or numbering lists.

01:48:28They were originally added

01:48:30to serve as protection.

01:48:32At the time, rats were a real problem

01:48:34in houses,

01:48:36and paper was one of their favourite means.

01:48:38Marks were used

01:48:40as a security device.

01:48:42Rats would rather nibble on the white paper

01:48:44that encircled the part intended for writing.

01:48:46This hole in the stem

01:48:48of your donut

01:48:50is used to prevent suffocation.

01:48:52It's used to keep the donut in place.

01:48:54The water-filled confectionery

01:48:56goes into the hollow of the donut

01:48:58and, once solidified,

01:49:00holds the donut in place.

01:49:02In this process, it would be more fragile

01:49:04and would come off easily.

01:49:06Vacuum cleaners have a lot of accessories,

01:49:08but do we really know

01:49:10what this long-haired brush is for?

01:49:12It's useful for dusting

01:49:14and its shape is perfect

01:49:16for cleaning frames, curtains,

01:49:18and doors.

01:49:20What's the difference between a wooden belt

01:49:22and a plastic belt?

01:49:24Not only does a cedar wooden belt

01:49:26allow you to match the shape of your clothes,

01:49:28but it also repels mites

01:49:30and other insects.

01:49:32Salt is not only useful in the kitchen.

01:49:34It can get rid of strong odours.

01:49:36Rubbing salt on your fingers

01:49:38after chopping garlic

01:49:40should get rid of the odour.

01:49:42It also works for shoes.

01:49:44Gripens have a secret drawer

01:49:46where you can store all these

01:49:48annoying crumbs of bread.

01:49:50If you can't get a chocolate out of the box,

01:49:52look at these little holes next to it.

01:49:54They're there to help you.

01:49:56If you press one of these holes,

01:49:58the chocolate will come out easily.

01:50:00When you drink a sip of coffee

01:50:02in a cup with a lid,

01:50:04the pressure in the cup decreases

01:50:06and the air tries to get in.

01:50:08The little hole on the lid

01:50:10allows the air to flow

01:50:12and the drink can flow

01:50:14and it's not over yet.

01:50:16The little pressure on the top of the lids

01:50:18is used to inform the staff

01:50:20as well as the customers

01:50:22about the contents of the cups

01:50:24in order to differentiate them.

01:50:26There's a legend about each little hole.

01:50:28You just have to look at which one is in

01:50:30to know what it belongs to.

01:50:32The numbers on the fruit labels

01:50:34give us information about

01:50:36how they were grown.

01:50:38If there are four numbers,

01:50:40the first of which is a 4 or a 3,

01:50:42if there are five numbers,

01:50:44the first of which is an egg,

01:50:46it's from organic farming.

01:50:48If there are five numbers,

01:50:50the first of which is an 8,

01:50:52it has undergone genetic modifications.

01:50:54When you're on your way to your car

01:50:56after you've finished packing all your groceries,

01:50:58remember to use the hooks on the cart

01:51:00to hang the bags.

01:51:02This way, the most fragile items,

01:51:04such as bread, eggs or fruits and vegetables,

01:51:06won't be crushed by heavier products.

01:51:08If you don't have anyone with you

01:51:10to measure something,

01:51:12you just have to nail it.

01:51:14Place your nail

01:51:16at the level of the dedicated little hole

01:51:18where the tape measures are usually placed

01:51:20and you just have to unroll it.

01:51:22The McFlurry's square spoon

01:51:24is designed to easily mix

01:51:26the fillings with the ice.

01:51:28It attaches directly to a machine

01:51:30and starts spinning.

01:51:32The outside hooks suck up quickly

01:51:34because of the rain.

01:51:36You see this little hole down there?

01:51:38It's an engine oil pump.

01:51:40This trick lubricates the mechanism

01:51:42and the key should spin again effortlessly.

01:51:44You've been tapping on the bottom

01:51:46of the bottle of ketchup for two hours,

01:51:48but nothing comes out.

01:51:50Here's a little trick.

01:51:52Put the bottle diagonally

01:51:54and tap it towards the middle of the neck.

01:51:56In many fast foods,

01:51:58customers have folded paper cups

01:52:00to use ketchup or mustard.

01:52:02Ready for the scoop?

01:52:04These little ramekins are actually

01:52:06a sauce container.

01:52:08The little hole on the handle

01:52:10of the saucepan or pan

01:52:12is not only used to hang them on the wall.

01:52:14While you're cooking,

01:52:16place the end of the utensil handle

01:52:18that you're using in this hole.

01:52:20It will be held above the preparation

01:52:22that is being cooked

01:52:24and will prevent splinters.

01:52:26The color pans of a toothbrush

01:52:28are there to tell us

01:52:30when it's necessary to change them.

01:52:32If you notice that these pans

01:52:34don't fit,

01:52:36change toothbrushes

01:52:38or just your head,

01:52:40depending on the case.

01:52:42The upper hole of the sink

01:52:44has many functions.

01:52:46First, it prevents water from overflowing

01:52:48if someone forgets to close the tap.

01:52:50It also allows water to evaporate

01:52:52faster, allowing the air to escape

01:52:54while the water flows.

01:52:56Most of the metal closures

01:52:58have a hidden locking system

01:53:00that can save you from awkward moments

01:53:02when the water stops automatically.

01:53:04All thanks to these little notches

01:53:06placed under the tap.

01:53:08Perimetal milk produces gases

01:53:10like most perimetal foods.

01:53:12Some plastic milk cans

01:53:14have a concave part on one side.

01:53:16If the milk spins and produces gases,

01:53:18this part of the bottle will inflate

01:53:20and the concave shape becomes convex.

01:53:22The same thing will happen

01:53:24if you put the can in the freezer.

01:53:26Solidified milk takes up more space

01:53:28than liquid form.

01:53:30It makes you feel good.

01:53:32It also regulates the temperature.

01:53:34The bubbles keep the water warm

01:53:36and you can enjoy your bath

01:53:38longer.

01:53:40However, this only works for acrylic baths.

01:53:42These are made of metal

01:53:44and lose heat quickly in all cases.

01:53:46Many cups and mugs

01:53:48have small grooves on the bottom.

01:53:50This is designed for dishwashers.

01:53:52They allow water to flow

01:53:54and thus avoid getting everywhere

01:53:56when going out of the dishwasher.

01:53:58The small grooves

01:54:00in the cream tube caps

01:54:02are also useful.

01:54:04Most of the tubes

01:54:06are sealed with aluminum.

01:54:08It's impossible to drill

01:54:10without saying goodbye to your nails.

01:54:12These grooves

01:54:14open all the cream tubes,

01:54:16even the most resistant ones.

01:54:18The escalator brushes

01:54:20are not used to clean

01:54:22and polish your shoes.

01:54:24Applying wax on a moving escalator

01:54:26is a matter of safety

01:54:28as it prevents users

01:54:30from approaching the edge of the steps.

01:54:32It reduces the risk

01:54:34that the bottom of a long coat

01:54:36or pants will get stuck

01:54:38between the steps.

01:54:40All the tic-tac boxes

01:54:42are designed to only

01:54:44let out one tic-tac at a time.

01:54:46The lid is shaped like a candy.

01:54:48Turn the box down,

01:54:50shake it gently and open it.

01:54:52You'll see there's only one candy

01:54:54in your mouth,

01:54:56so you don't know how to eat tic-tacs.

01:54:58At first, the candy on the caps

01:55:00wasn't just a fashion accessory.

01:55:02It prevented sailors

01:55:04from hitting their heads

01:55:06on the ceiling of ships.

01:55:08There are a lot of amazing things

01:55:10you can do with products

01:55:12that you have at home

01:55:14and are intended for other uses.

01:55:16We're going to explore

01:55:18some of these possibilities

01:55:20as well as articles

01:55:22that you may not be aware of.

01:55:26Many kitchen scissors

01:55:28have a lace opening

01:55:30where the handles and blades meet.

01:55:32You can use it to peel

01:55:34difficult herbs like thyme,

01:55:36rosemary and chives.

01:55:38It saves you time

01:55:40trying to remove the leaves by hand.

01:55:42And if you're short of vases,

01:55:44you can give roses

01:55:46to the ones you like this way.

01:55:48Just be careful where you point

01:55:50your kitchen scissors.

01:55:52The metallic blade of soda cans

01:55:54can be turned around

01:55:56so you can slip a straw in

01:55:58and avoid carrying the can in your mouth.

01:56:00This blade has also replaced

01:56:02the traction ring created in the early 60s.

01:56:04You remember those, don't you?

01:56:06They were quite sharp

01:56:08and easy to remove

01:56:10and posed a danger to others.

01:56:12Now you can slide your straw

01:56:14directly into the blade

01:56:16and also make bubbles.

01:56:18Sometimes when you buy

01:56:20a new garment,

01:56:22a small plastic bag is attached

01:56:24with an extra button

01:56:26and a piece of fabric.

01:56:28If the fabric is often used

01:56:30to repair any holes,

01:56:32it can also be used

01:56:34to test the effects

01:56:36of various detergents on the garment.

01:56:38It is also practical

01:56:40to test the washing programs

01:56:42before washing the entire garment.

01:56:44You can use a screwdriver

01:56:46if you have trouble lifting

01:56:48or moving something.

01:56:50Some also have a hexagonal handle

01:56:52that fits inside a wrench.

01:56:54You can use it to increase

01:56:56the tightening and,

01:56:58once again, to lever.

01:57:00Practical for those

01:57:02who don't have much strength in their arms.

01:57:04Elastics are useful

01:57:06for many things,

01:57:08but if you have a bottle

01:57:10or a jar that is difficult to open,

01:57:12you can wrap the elastic

01:57:14The mechanical stairs

01:57:16have these black brushes on the sides

01:57:18for the same reason that there are

01:57:20sometimes yellow lines on the steps,

01:57:22to dissuade people from getting

01:57:24too close to dangerous places.

01:57:26People don't always pay attention

01:57:28and sometimes clothes or laces

01:57:30can be dangerously close

01:57:32to the place where the step

01:57:34meets the edge or the skirt.

01:57:36The brush is a little safety

01:57:38to prevent this from happening.

01:57:40It can also prevent pieces of plush

01:57:42from falling into the gaps.

01:57:44Your jeans have several features

01:57:46that are very functional,

01:57:48although a little out of fashion.

01:57:50The metal rivets around the pockets

01:57:52help to secure the tension points.

01:57:54This allows them to last a little longer

01:57:56than the average,

01:57:58although not all jeans are equipped with them.

01:58:00Many jeans still have a tiny pocket

01:58:02directly above the main pocket.

01:58:06Originally, it was intended

01:58:08to contain a watch.

01:58:10Although these watches belong

01:58:12mostly to the past,

01:58:14many people still use this space

01:58:16to store coins, a ring

01:58:18or even a mini USB key.

01:58:20It may seem a little obvious,

01:58:22but if you're wondering

01:58:24what all the grooves on a car tire

01:58:26are for, it's for road grip.

01:58:28That said,

01:58:30they are also a good indicator

01:58:32of the wear of your tire.

01:58:34If these grooves are no longer

01:58:36as deep and almost cover the road,

01:58:38it's time to change your tires.

01:58:40If you don't,

01:58:42the next time you try to stop

01:58:44suddenly at a red light,

01:58:46you may be surprised to see

01:58:48that your car has turned

01:58:50into a giant roller coaster.

01:58:52These carry-on boxes,

01:58:54often associated with Chinese restaurants,

01:58:56are designed not only to carry

01:58:58your food home,

01:59:00but also to store it in the refrigerator.

01:59:02They also serve as plates

01:59:04because you can eat directly in them

01:59:06They were patented

01:59:08in 1894

01:59:10to carry freshly chopped oysters

01:59:12and were known as

01:59:14oyster buckets.

01:59:16They were then adapted

01:59:18to serve as water containers

01:59:20for food.

01:59:22When you're sitting in a plane

01:59:24and you look out the window,

01:59:26you may have noticed these little holes

01:59:28or, in some cases,

01:59:30a singular opening at the bottom.

01:59:32It's called an air hole

01:59:34to balance the air pressure

01:59:36that accumulates between

01:59:38the pressurized cabin

01:59:40and the outside atmosphere,

01:59:42especially at high altitudes.

01:59:44It also releases humidity

01:59:46between the windows

01:59:48to prevent frost from forming

01:59:50on the windows and obstructing

01:59:52such a beautiful view.

01:59:54Sorry, but you won't be able

01:59:56to draw a smiley face right away.

01:59:58The first cutter

02:00:00was introduced in 1956

02:00:02by a Japanese company.

02:00:04They were inspired

02:00:06by chocolate bar squares.

02:00:10Almost all cutters

02:00:12have an empty slot

02:00:14in their metallic ends.

02:00:16It's called a nail clip

02:00:18and you can attach it to a nail

02:00:20or a screw.

02:00:22It's a practical trick

02:00:24to make measurements

02:00:26without needing someone else

02:00:28to hold it in place.

02:00:30You can attach a groove

02:00:32to one of the branches

02:00:34to keep your hair in place.

02:00:36The straight side

02:00:38should be at the top

02:00:40while the grooves

02:00:42should be against your head.

02:00:44They are also called

02:00:46bob cutters

02:00:48because of the bob hairstyle,

02:00:50that is, the square cut

02:00:52that was popular in the 1920s

02:00:54although the cutters

02:00:56were invented in the 19th century.

02:00:58Have you ever noticed

02:01:00the black dots on the windshield

02:01:02of a car or a bus?

02:01:04You probably know

02:01:06that it's not for decoration.

02:01:08They are called fritters

02:01:10and it's a ceramic paint.

02:01:12Their main purpose

02:01:14is to protect the window

02:01:16from ultraviolet rays.

02:01:18It also creates a rough surface

02:01:20where the adhesive can stick.

02:01:22If you see a piece of pink adhesive

02:01:24in a corner, don't touch it.

02:01:26If you take a look

02:01:28at the bottom of a padlock,

02:01:30there is a good chance

02:01:32that you see one or two small holes.

02:01:34They are used to evacuate

02:01:36the water trapped inside

02:01:38because of the rain.

02:01:40This mini drainage system

02:01:42prevents the internal operation

02:01:44of rust or frost

02:01:46if it is very cold.

02:01:48And if the padlock gets stuck,

02:01:50you can put a product

02:01:52with oil inside

02:01:54to lubricate it

02:01:56and make it work again.

02:01:58If you've lost the key

02:02:00and you want to ease your frustration,

02:02:02you can scream in the holes.

02:02:04It won't open it,

02:02:06but you'll feel a little better.

02:02:08Some shirts

02:02:10have a fabric buckle in the collar.

02:02:12It is used to suspend the shirt.

02:02:14The buckles would have been used

02:02:16for the first time in the Navy

02:02:18because it was easy

02:02:20to simply hang them on the wall.

02:02:22In the 1960s colleges,

02:02:24the fashion was to wear

02:02:26the buttoned shirt up to the top,

02:02:28which made everything more complicated.

02:02:30So the designers

02:02:32started to put the buckle in the back.

02:02:34If the student removed the buckle,

02:02:36it meant he was

02:02:38in a stable relationship,

02:02:40unless one of his friends

02:02:42took it off

02:02:44to make a joke out of him.

02:02:46And now everyone wonders

02:02:48with whom he goes out.

02:02:52Have you ever wondered

02:02:54why the coins have these little grooves

02:02:56on the edges?

02:02:58It's a vestige of the old days

02:03:00where they were more valuable.

02:03:02The blacksmiths could easily

02:03:04file the edges of the coins

02:03:06to make other gold or silver ones.

02:03:08The grooves were created

02:03:10to make it much easier

02:03:12to tell if a coin has been filed.

02:03:14It's no longer necessary today,

02:03:16but the coins still have this detail.

02:03:18And if you ever get bored,

02:03:20counting the number of grooves,

02:03:22you can watch

02:03:24another nice video.
