00:00Watch this. I can make the palm of your hand move.
00:03Just stare at the center of this image.
00:05You'll see a bunch of letters.
00:07Read them in your mind and don't look away.
00:10Keep focused and do your best not to blink.
00:13Now, when I count down from 5,
00:15I want you to look at the palm of your hand super fast.
00:19Ready? Here we go.
00:215, 4, 3, 2, 1.
00:25Look now. Wow!
00:27Does it look like it's moving?
00:29That's crazy.
00:31Now, what do you see here?
00:33If those blue bars look tilted to you,
00:35let me just say it's all in your head.
00:38These horizontal lines are all straight and parallel.
00:41Don't believe me?
00:43Okay, let's get rid of those tiny black and white squares.
00:46See? No weird angles here.
00:48Just your brain tricking you.
00:51So, is the shape spinning around itself like a hula hoop?
00:55Or is it coming straight at you?
00:57Well, it depends.
00:59If we drop a vertical line in the middle,
01:01it looks like it's spinning sideways.
01:04But if we switch to a horizontal line,
01:06suddenly it's moving in a whole different direction.
01:09Nope, there's nothing wrong with your vision.
01:12This image really is super blurry.
01:15But you can tell it's a woman looking to the left, right?
01:19Now, watch what happens when we remove the blur.
01:22Boom!
01:23Crystal clear.
01:24But hold up!
01:25Was she actually looking straight ahead the whole time?
01:28Well, looks like it.
01:30This strange optical illusion totally changes depending on how you look at it.
01:36At first glance, you're probably seeing an illusion of what looks like a European villa.
01:42But now, let's make it really small.
01:45And who do you see?
01:47Yep, it's Mona Lisa.
01:49The trick is called a hybrid image.
01:54These lines are way cooler than they look.
01:57Just stare at the picture and move your head really fast, like as fast as you can.
02:02Did you just see a woman's face appear out of nowhere?
02:06These cubes are not moving.
02:08I know, it's hard to believe.
02:09But the only thing actually happening here is that the colors are shifting from light to dark.
02:15And for some reason, our brains totally misinterpret that as movement.
02:20Here's another crazy illusion.
02:23When still, it just looks like a simple geometric design.
02:26But the second we move it up and down,
02:29whoa!
02:30Suddenly all those lines start wiggling like crazy.
02:34Now, this one is insane.
02:36Look at the blue and red lines.
02:38They totally seem to change sizes, right?
02:40Well, guess what?
02:42They don't.
02:43Every single one is the exact same length.
02:46The only thing messing with your brain are those little arrow tips at the ends.
02:51And the same trick is at play here.
02:54The blue and black segments of this star are identical in length.
02:57They just look like they're stretching and shrinking because of those sneaky arrows.
03:03This armchair is hiding something pretty cool.
03:06Think fast.
03:07Does this shade of green look darker or lighter than this one?
03:11Got your answer?
03:13Well, surprise!
03:15They're actually the exact same color.
03:17If we isolate them, you will see it clear as day.
03:22Next.
03:23See how the white circle in the center looks way brighter than the rest?
03:27Almost like it's glowing.
03:29Well, guess what?
03:30It's actually not any brighter than the white lines at the edges of the image.
03:34Now, keep staring at the center of this image.
03:39Try your best not to blink and keep focused.
03:42I know, I know.
03:43This swirling motion is dizzying.
03:45But trust me, it'll be worth it.
03:47Because when I count to three, you are going to see the universe moving.
03:51Yep, that's right.
03:52The next image I show you will be completely still, but your eyes will be so hooked on this
03:57motion that it looks like it's moving.
04:00Ready?
04:011, 2, 3, go!
04:04Wow, that's insane!
04:05There is something hidden in this image, but your eyes might be playing tricks on you.
04:11I'll give you a moment.
04:12Can you spot it?
04:22Time's up!
04:23Surprise!
04:24There's a woman's face hiding right there.
04:27Take a look at the lines.
04:29What direction do you think they're moving?
04:31Bet you said, from the head to the tail of the snake, right?
04:35Well, hold on.
04:37Watch what happens when we keep changing the colors, making them lighter and darker.
04:41Suddenly, the direction looks different.
04:44What kind of sorcery is this?
04:47Here's a simple black and white image.
04:49But when we move it, it looks like bright fleeting rays are coming out of the center.
04:54But don't get it twisted, those rays aren't actually there.
04:58It's just your brain doing its thing, making it look like they are.
05:02Now, this one might be a little tricky to spot.
05:06But don't worry, I'll give you some time to find the heads of two different people hidden here.
05:10Let's start the countdown.
05:11Alright, so the first head is easy to find.
05:23But here's the twist.
05:25When we flip it upside down, it becomes a whole different face.
05:29One cheekbone turns into a nose, and the mouth becomes a squinty eye and an eyebrow.
05:34Can you see it now?
05:35Okay, so you probably see some sort of square right in the middle of this image.
05:41But here's where it gets interesting.
05:43We can all agree that this image is totally static, right?
05:47But now, try moving your head up and down.
05:50Keep going, then try left and right.
05:53Does it look like it's actually moving?
05:57Take a close look at this image and answer me this.
06:00How many different colors of spheres do you see here?
06:03One, two, or three?
06:05Well, guess what?
06:06The answer is none.
06:08Yep, they're all the same shade.
06:11If you look beyond the lines, it becomes crystal clear that it's just a sneaky optical illusion.
06:18Okay, here's another sphere.
06:19But this one's a little different.
06:21It looks 3D, right?
06:23But it's not.
06:24And if we shake the image up and down, the effect will get even stronger.
06:28This is a great example of an ambiguous image.
06:33You know, like pictures that can be two things at once.
06:35So, what do you see here?
06:37Can you pick out the two different interpretations?
06:49Time's up!
06:50It's a man and a mouse.
06:52If you couldn't spot it, no worries.
06:54I've got you.
06:55Picture the mouse's tail as the man's chin.
06:58And those mouse ears as his eyeglasses.
07:01Uh-huh.
07:03This image might reveal some interesting things about you.
07:07So, take a good look and tell me, what's the first thing you saw here?
07:11If you spotted an eagle, that means you're probably a super charismatic person by nature.
07:16People are just drawn to your magnetic personality.
07:19But if you saw a mountain, well, it looks like you are hardworking and love spending time being productive.
07:26Does that sound like you?
07:27Yeah, me neither.
07:28Let's move on.
07:30Now, this might look like a simple checkerboard at first, but those white and black dots between the squares are messing with our brains, making you see waves here.
07:39If you can't quite see it, let me help you out.
07:42Let's shrink this whole image down.
07:44Can you spot that bizarre effect now?
07:47Okay, by now you are pretty much a pro at optical illusions.
07:51So, can you figure out what's weird about this one?
07:55Yep, those gears aren't actually moving at all.
07:58It's just the changing color contrast in the background that makes it look like they are.
08:04We can't wrap this video up without talking about the dress.
08:09Yep, that one.
08:10But hold up.
08:11Now there's a new version of this viral illusion.
08:14Say hello to the shirt.
08:16So tell me, what color do you see?
08:19Are you team black and blue or team white and gold?
08:23Drop your answer in the comments.
08:25Now, let me clear up something for you.
08:27If you see this shirt in bright colors, just know it's your brain playing tricks on you.
08:33It's actually blue and black.
08:35So I guess we can finally put an end to this debate even before it starts.
08:42That's it for today.
08:43So hey, if you pacified your curiosity, then give the video a like and share it with your friends.
