00:00Wow, something bizarre is about to go down.
00:03Focus on this cross right here.
00:05Ignore the wild celebrity roulette spinning around the edges.
00:09And whatever you do, don't blink.
00:11Just keep staring at the cross in the middle.
00:14Now tell me, do you notice how our favorite stunning celebrities are starting to look
00:18like something out of a monster movie?
00:21No special effects are happening here, trust me.
00:24All of this is purely in your mind.
00:27So when you're presented with a series of eye-aligned photos, one after the other,
00:32your brain kind of glitches, mixing them up and making them look distorted.
00:36Before you know it, even the most flawless features of Hollywood's Barbie and Ken,
00:41I mean Margot Robbie and Ryan Gosling, begin to look twisted, squashed, or stretched.
00:46Ooh, the chills!
00:48Here we have an animation of four faces flipping between Selena Gomez and Demi Lovato.
00:54But are you ready for a spin?
00:56These faces will keep switching back and forth between the two of them, but now they'll
01:00also be spinning in a circle.
01:03Fix your gaze on this cross and resist the urge to look away.
01:07If you stay focused right on the center, you'll find it almost impossible to spot the morphing
01:11between their faces.
01:13The transition seems delayed, like it's barely happening.
01:17But the moment we stop the spinning motion, BAM, it's pretty clear that the morphing
01:22animation was happening the whole time at the same speed.
01:27Meet the rotating rays illusion.
01:30If you're seeing what I'm seeing, the outer ring looks like it's moving clockwise,
01:34while the inner ring seems to spin counterclockwise.
01:38But what's strange about it is that these circles aren't moving at all.
01:42Our eye movements play a huge role in creating this effect.
01:45I mean, when you keep shifting your gaze around the image, the illusion of motion continues.
01:51But can we make things more interesting by placing a picture of Kim Kardashian right
01:55in the center?
01:57Focus just on her face and try your best not to blink.
02:01Notice how the rings seem to slow down or even stop?
02:04Bizarre, huh?
02:06This illusion was created by a Japanese professor known for designing tons of mind-bending illusions.
02:12Like this one, where it looks like rollers with blue dots are turning towards each other.
02:16Or this one, where yellow rings seem to move up and down, almost as if they're getting
02:21closer together.
02:23But again, these aren't animations or GIFs.
02:26The motion is only happening in your mind.
02:31The painting The Scream is scary on its own.
02:35But one optical illusion can make it even weirder, practically bringing it to life.
02:40If we throw in a little zooming in and out motion to Munch's iconic work, the haunting
02:45face seems to grow and shrink, almost as if it's jumping out at you.
02:50It makes The Scream feel all too real, right?
02:54Of course, this after-effect illusion isn't just for paintings.
02:57We can do the same with a photo from Rihanna's concert.
03:01Fix your gaze on the middle of the image, and you'll start to see her move, almost
03:05like you're getting a front-row seat to a live performance.
03:08Alright, maybe it's not quite as cool as seeing Rihanna actually perform, but it's
03:13still pretty awesome.
03:16Next we have this pretty ordinary checkerboard image.
03:19But I'll ask you to pay special attention to the squares marked with the letters A and
03:24B. So, are they the same color or different?
03:28Most people confidently say that square A is darker and B is lighter.
03:33But what's bizarre about it is that they are actually the same exact shade of gray.
03:37Ooh, one of 50 shades of gray?
03:40Sorry, I couldn't help it.
03:42Anyway, how does this magic happen?
03:44Well, the square labeled B is sitting in the shadow of that cylinder.
03:49Your brain automatically thinks, hey, shadows make things darker.
03:53So it brightens square B to adjust for the shadow, while square A, which is outside of
03:58the shadow, is left as it is.
04:01Let's talk about the paperclip illusion.
04:05If you take a simple grid and add perfectly straight diagonal lines, something strange
04:10happens.
04:11They look bent or kinked.
04:13It's called the paperclip illusion because some people think that the lines resemble
04:17a row of paperclips.
04:19Can't see it?
04:20Well, there is a way to fix that.
04:21If you look at the image from the corner of your eye, the effect gets stronger.
04:26So let's put a photo of Timothee Chalamet in the corner.
04:30Fix your gaze on him, and in your peripheral vision, you'll notice those straight lines
04:34now seem bent like a bunch of paperclips floating around.
04:38Can you see it now?
04:40Another interesting thing is that the effect changes if you adjust the thickness of the
04:44lines.
04:45Make them thicker, and instead of paperclips, the illusion shifts to something that looks
04:49like chains.
04:51But if we do the opposite, making the lines thinner, they'll look more like wavy ribbons.
04:57Here we have photos of two pairs of Crocs.
05:00And we can all agree that this one is pink and this one is green, right?
05:04Awesome!
05:05But let's make it a bit harder with this new picture.
05:08So what color are these Crocs?
05:10Take a good look and tell me.
05:12Which option do you think you just saw?
05:15Number 1, number 2, or number 3?
05:18Got your answer?
05:20If you guessed option 1, you are correct.
05:23These Crocs are actually pink, but they look gray because there's a green filter over
05:28the image.
05:29The lighting tricks our eyes into seeing colors differently.
05:32White things, like these socks, turn green, while pink things, like these Crocs, turn
05:37a kind of gray.
05:39This color constancy illusion proves just how much lighting can deceive our brains.
05:45There was one more pink illusion for you.
05:48This time, we have an image with a white circle in the middle.
05:51But now let's add some motion to it.
05:54I know this animation is intense, but keep staring at the black X in the center.
05:59Suddenly that white circle seems to take on a soft pink hue.
06:03It's almost as if the red and white pixels around it are blending together.
06:07A similar thing happens with this red and white checkerboard.
06:10Keep focusing on the black X again right in the center, and will you notice that when
06:15the checkerboard suddenly changes to all white, the red spaces still might look faintly pink?
06:22One explanation is that when you stare at the X, your eyes get used to seeing the red
06:26and white edges.
06:28This adaptation effect leaves an afterimage in your vision, and your brain holds onto
06:32the red so strongly that when it's removed, it fills in the white with a touch of pink.
06:40For our final trick, we have an illusion called the Poggendorf Triangles.
06:45What do you see when you look at this weird shape?
06:48So you might see it as two triangles put together.
06:51One here and the other one here, right?
06:53That makes sense, but that is not the correct answer.
06:57I mean, yeah, there are in fact two triangles in this image, but not in those positions.
07:02What's happening is that your brain probably thinks there's an imaginary diagonal line
07:07running through them, like those two edges are connected and part of a single line.
07:11But the truth is that those edges don't connect at all.
07:15See?
07:16They're actually two distinct lines that don't line up.
07:19Like I said earlier, there are indeed two triangles in this image, just not in the way
07:24we expect.
07:25Let's separate these shapes, and wow, there they are!
07:29This illusion works because when we see objects that are partly hidden, our brains sort of
07:34create imaginary outlines to make things seem more logical.
07:39But those outlines aren't actually there.
07:41The same happens here.
07:43Your brain thinks this image is just bizarre and then tries to figure it out by filling
07:47in the empty spaces in the middle.
07:50So you end up seeing the gray areas as part of a single translucent rectangle, which definitely
07:55doesn't exist.
07:57Crazy, huh?
08:00That's it for today!
