00:00Here's something weird for you.

00:02Stare at this image for a few seconds.

00:04Really lock in on one spot in the middle.

00:07I know, the edges seem to fade, almost vanishing, into thin air.

00:11And then, out of nowhere, those empty spaces take on a greenish tint.

00:16What's really going on here?

00:18Well, this little mind trick is called the Troxler fading illusion.

00:23When you focus too hard on one point, your brain decides that the rest isn't worth

00:26paying attention to.

00:28It's like it's saying something new is happening, so it just filters it out.

00:33So while you think you're seeing everything, your brain is low-key erasing the background.

00:37Now check out this image.

00:39Which line do you think continues the black one?

00:42The red line?

00:43Or the blue line?

00:45Your brain is probably screaming blue, but it's actually the red one.

00:49This tricky visual is called the Poggendorf illusion, first described back in the 1960s.

00:56It messes with how we see geometric shapes and depth.

00:59Basically, our brains are wired to interpret 2D images as if they have 3D properties, and

01:05in the process, they warp the way we perceive alignment.

01:10I need you to stare at this image for a second.

01:13Does that dark hole in the center seem to grow, like you're being pulled into a tunnel?

01:19This is called the expanding black hole illusion.

01:23Scientists have found that when people look at it, their pupils dilate, just like they

01:26would if they were stepping into a real dark space.

01:30That's because your brain is wired to predict light changes, and when it thinks you're heading

01:34into a cave or tunnel, it adjusts your vision before you actually get there.

01:40FYI, the illusion isn't moving at all, your brain just fills in the blanks.

01:46The next illusion will prove that your brain is photoshopping reality without your permission.

01:51Take a look.

01:53Can you spot the darkest one?

01:54Okay, good, but I have something to tell you.

01:57They're all the same color!

02:00This is the saturation illusion in action.

02:03Your brain doesn't just see colors, it interprets them.

02:06Stick the same gray on a dark background, and it magically looks lighter.

02:11Put it on a light one, suddenly it's darker!

02:15Just keep looking at the little white dot at the center of this image for a bit.

02:19Don't worry, I'll tell you when you can stop.

02:21We need your full attention for just a few seconds.

02:24When I say go, I'll need you to stare directly into a white wall or a blank piece of paper.

02:293, 2, go!

02:32Now, this is called the negative afterimage illusion.

02:36First, you need to look at an image with inverted colors for a few seconds.

02:41Then when you turn to look at a white page or wall, you'll get to see the original image.

02:46This is scientific!

02:48This trick happens because your eyes and brain are big fans of contrast.

02:54When they're hit with opposite colors, they try to balance things out by filling in the

02:58right colors.

02:59So even though the screen's blank, your mind plays color artist and paints the correct

03:04shades in your imagination.

03:07If you've never seen a picture literally undulating, then let me show you this.

03:12If you move the screen up and down, it will make it even more exciting.

03:16This is the primrose's field illusion, and these squares seem to ripple like little waves

03:21on the ocean, even though nothing is actually moving.

03:25It's all thanks to tiny involuntary eye movements called fixation jitters.

03:30Your eyes are constantly shifting, even when you think they're steady.

03:34On top of that, your brain processes light and dark areas at different speeds, creating

03:39a delay that makes the pattern seem to sway.

03:42Basically, your brain is making up movements that aren't there.

03:46Let me out here for a second.

03:47Can you tell if the circle on the right is larger than the circle on the left?

03:51They're actually the same size.

03:53Yep, your brain just got bamboozled by the Ebbinghaus illusion, a sneaky trick discovered

03:59by a German physiologist over a hundred years ago.

04:02The big circles on the right make the middle circle seem tiny, while the smaller circles

04:06on the left make their center buddy look huge.

04:11Don't these ones look like they're rotating?

04:13Now blink a few times.

04:15It's insane how it seems to get faster, right?

04:19This is one of Japanese artist Kitaoka's optical illusions.

04:23These illusions are shapes with changing brightness and contrast to create the effect of rotating

04:28images.

04:30Let's see another example.

04:32Which direction are these snakes moving to you?

04:35This may shock you, but these guys are stationary.

04:38It's all about those repeating asymmetrical patterns and clever color combos.

04:43You've got lighter shades like yellow and white hanging out with darker blues and blacks.

04:48This funky mix tricks your retina into sending signals to your brain, making those circles

04:53look like they're spinning.

04:55Alright, stare at the parrot's eye for 15 seconds.

04:59You can't blink, you can't look away.

05:01I'll let you know when it's time to close your eyes.

05:053, 2, 1.

05:07Now close your eyes.

05:09Ok, can you see a red parrot in your mind?

05:12It might feel like a trick, but this is another cool example of the after-image effect.

05:18Here's what happened.

05:20Even though the parrot in the picture is black and white, your brain got a little confused

05:24after staring at that bright high-contrast eye for so long.

05:28Is this red car really moving like crazy in the other direction?

05:32Let's see.

05:34Focus your sight on the moving vehicles.

05:37Now fix your eyes on the red car.

05:39Is the picture starting to change?

05:42If you manage to focus your gaze on the red car, you'll start to see it's slowly moving

05:46forward, and all the other cars are moving backwards.

05:50Take a look at this image.

05:52It looks like the square in the middle is breathing, right?

05:54Like it's growing in size and then shrinking.

05:57What if I told you that it's just rotating, but it's not changing size?

06:02Here's what's really happening.

06:04This illusion is called motion binding.

06:06It happens when our brain tries to predict the movement of one of the elements in the

06:10image.

06:12Here's one for you.

06:13These four bars seem to be moving in parallel with each other, right?

06:17Wrong.

06:18They're all part of the same moving square.

06:20Here's what's happening behind the scenes.

06:22Our brain just gets confused.

06:25Keep staring at this image of Harry Potter for a few seconds.

06:28Focus your eyes on this dot.

06:31You can blink, but keep staring at the dot.

06:34When I say so, I need you to close your eyes and blink with your eyes closed.

06:38You know, just keep squeezing your eyes while they're closed.

06:41Okay, you can close your eyes.

06:43Now blink.

06:44A portion of Harry Potter will slowly start to appear in your mind's eye.

06:49Can you see it?

06:50That's witchcraft right there!

06:52Alright, here's the final illusion.

06:55What do you see here?

06:57Is it black and white?

06:59Go ahead, take your time, think about it.

07:02But here's the thing.

07:03Your brain is probably already trying to trick you into thinking there are colors all over

07:08this photo.

07:09What you're actually looking at is a black and white image with a bright, colorful grid

07:13of green, red, orange, yellow, and blue lines placed over it.

07:18The grid's super vibrant colors play tricks on your brain, making the grayscale photo

07:23appear all colorful and lively.

07:26The lines add a bit of saturation to the whole thing, causing you to see colors where there

07:30are none.

07:31It's like your brain is getting excited, thinking, whoa, this is way more colorful

07:36than I expected!

07:38If you really want to break the illusion, try zooming in on the image.

07:42When you do, you'll see that the photo isn't full of color at all.

07:46The colors you were seeing were just a little magic trick your brain pulled, trying to make

07:50sense of the colors it thought it was seeing.

07:54That's it for today!
