FunTranscript
00:00Look at these lines very carefully. What can you say about them?
00:05I bet these rows seem to tilt alternately.
00:08To be honest, I felt a little stunned just by looking at them.
00:12But in reality, the lines are parallel.
00:15It is the pattern of the rows that creates this incredible optical illusion.
00:19And if you don't believe me, pause the video and check for yourself.
00:25Now, what do you think about these rings?
00:27They seem to turn in different directions.
00:29But in reality, the rings never change position.
00:33The image is fixed.
00:34The only thing that changes is the color of the petals.
00:38What you see now is what is called a color context illusion.
00:43The top circle seems to be darker than the bottom one, doesn't it?
00:47In reality, these circles are of the same shade of red.
00:51This illusion proves that the color of the background can influence the way our brain perceives the color of an object.
00:58Despite the appearances, this turning disc optical illusion is not a gif.
01:03It is an immobile image, even if the snakes seem to turn in front of your eyes.
01:10This optical illusion is based on the way your eyes process images.
01:15They scan it several times, constantly self-adjusting.
01:19Now, here's what you can try.
01:22Focus intensely on a single snake.
01:25And voila! All the movement has stopped.
01:29This next image will amaze you.
01:32Even if we already know how this principle works, our eyes continue to deceive us,
01:36making us believe that the square on the left is much clearer than the one on the right,
01:40when in reality, their shades are exactly the same.
01:44You can check.
01:45Remember, everything is a matter of background.
01:49Here is the so-called coffee wall illusion.
01:51The rows in this image seem to be tilted up or down, don't they?
01:56But the horizontal lines are actually all parallel.
01:59If you want proof, pause the video and cover the top and bottom of a row of squares with a piece of paper.
02:05You will see that everything is straight.
02:07Look at the movement of these little blue and yellow lines.
02:10They seem to move alternately, like little feet that tap, tap, tap.
02:16This effect becomes even more pronounced if you do not look directly at the feet, but fix the space between them.
02:24Well, it's still an optical illusion.
02:27In reality, the movement of these small multicolored lines is always simultaneous.
02:34Look at this.
02:35Hmm, is it a little video?
02:37It looks like it.
02:39But if you focus, you will realize that the snowboarder does not really move forward.
02:45This illusion requires four images.
02:47The first two are the consecutive images of a video, and the next two repeat the first ones, but in negative.
02:55The reason why this illusion works is the simultaneous inversion of the contrast and the direction of the movement,
03:01which makes us believe that the snowboarder is moving continuously.
03:06This pattern is stationary.
03:08And yet, it seems to extend, its central part becoming larger and larger under your eyes.
03:14The effect is even stronger if you do not look directly at the image.
03:18The most confusing thing here is that not everyone can perceive this illusion.
03:23And no expert has yet understood why.
03:27Here is a rotating set made up of blue crosses and three yellow dots.
03:32Try to focus on the center, on this flashing red-green dot.
03:37It's magic, the yellow dots disappear from time to time.
03:41They disappear one by one, in pairs, or all three simultaneously, right?
03:46Well, not really, it's just an illusion.
03:49In reality, the three yellow dots are present all the time, believe me.
03:55Look at this rotating thing.
03:58It looks like a three-dimensional object, like a spinning top.
04:01But in reality, it is only an optical illusion created by the rotation of certain figures.
04:07You may not perceive the third dimension of the first blow.
04:11To get there, try to imagine a rotating crater.
04:16In this image, we see tracks of iron and two yellow lines.
04:21The one at the top is undoubtedly longer than the one at the bottom.
04:24But if you look closer, you will realize that the two lines have exactly the same length.
04:29This illusion is based on our perception.
04:32We tend to see this image with a linear perspective.
04:35And this makes us believe that the yellow line at the top is longer than the one at the bottom.
04:41When we look at this optical illusion,
04:44we have the impression that the background pattern revolves around a circle.
04:48In reality, the background and the circle remain completely still.
04:53But the effect is somewhat hypnotizing.
04:57The following illusion is rather cool,
04:59even if not everyone can see it at first glance.
05:02Follow the red dot with your gaze.
05:05Keep in mind that turning your head could help you.
05:09You will see that some of the squares in the background begin to move.
05:13Of course, in reality, they all remain still.
05:16The effect can be ephemeral for you, sometimes strong, sometimes absent.
05:20In any case, all the movement here, except for the moving red dot, is completely illusory.
05:26Look at this image.
05:28Are you sure that the circles do not move?
05:31Indeed, they seem to wave a bit like waves.
05:34This is due to a shift in the way we deal with visual information.
05:39When your eyes go from one part of the image to another,
05:42your brain believes that there is a movement.
05:45Oh oh, it looks like your brain is not as reliable as you thought.
05:49Frankly, this optical illusion has left me stunned and slightly confused.
05:53Look, the colors seem to swirl, don't they?
05:57But it's a fixed image.
05:59The effect is created by the combination of patterns and colors.
06:04To read the hidden secret message in this image,
06:07try to blur your vision a bit.
06:09To do this, you can slightly blink or fold your eyes.
06:13And there you go, the secret message is
06:16HIDE AND SEEK
06:18But if you look closer, the words will disappear completely.
06:23Look at this image in rotation.
06:25The wheel that forms the dark and light sectors turns in the direction of the needles of a watch.
06:30And the rays turn in the opposite direction of the needles of a watch, don't they?
06:34Now focus on the image by stabilizing your gaze.
06:38The rays are actually motionless.
06:41This image is also quite confusing.
06:44Can you tell me if the smallest point of this black and white illusion comes out or points inward?
06:50Contrasted lines do not allow us to determine it, so go figure.
06:55Another optical illusion that will question your perception of space.
07:00Which of these windows is the largest, in your opinion?
07:04At first glance, it seems that the one on the right is much larger than the other.
07:08But in reality, they are not only exactly the same size,
07:12but their upper and lower parts are perfectly aligned.
07:16Incredible!
07:17As soon as you look at this image, these four lozenges immediately jump out to your eyes.
07:22Interesting fact, no line creates these shapes.
07:25It is simply the contrast between black and white that makes your brain believe that lines exist.
07:31Some of the most misleading optical illusions can make your head spin.
07:35For example, let's take this one.
07:38On the left, the red squares seem to be deformed and twisted.
07:42But on the right, where all this strange arrangement of black and white lines has almost disappeared,
07:47we see that the red squares are perfectly straight and regular.
07:52Here is now the most brilliant of all the illusions.
07:55Look at these towers.
07:56Does one of them lean more than the other?
07:58But yes, of course, it is the one on the right.
08:01In fact, the appearances are misleading, because it is false.
08:04The two images are identical.
08:06It is the way they are positioned, one next to the other,
08:09that gives the impression that the one on the right is more inclined.
08:13Now, look at this image.
08:15Would you believe me if I told you that the lines that make up these squares are perfectly straight?
08:20Yes, all of them.
08:21Even the one in the middle.
08:23The mini squares inside the squares give the impression that the lines are curved.
