Optical illusions are amazing because they mess with your brain, making you see things that aren’t really there! Some images might look like they’re moving, but they’re actually totally still. Others can hide faces, objects, or colors, and it’s up to you to spot them. These illusions trick your brain by playing with shapes, colors, and patterns in clever ways. Looking at them can make you feel like you’re solving a puzzle, as your brain tries to make sense of the impossible. They’re a fun way to explore how our brains work and see just how easily our minds can be fooled!

00:00Okay, look at the center of the cross.
00:02No, don't get distracted by the celebrity's glam.
00:06Just keep staring at the cross.
00:08Go on, just a little longer.
00:11And suddenly, something weird starts happening.
00:14Those faces go from red-carpet gorgeous to downright bizarre, right?
00:19What kind of creepy spell is at work here?
00:21Well, we promise you, we didn't do any Photoshop magic.
00:24Look, if we stop this crazy roulette, and you focus on the photos, you'll see that
00:29Miley Cyrus still looks great.
00:31This optical illusion is known as the flash face distortion effect.
00:36Basically, these photos are arranged in a way that totally messes with our heads, and
00:40our brains love to compare things.
00:43So when the images switch really fast, and you see someone with a tiny nose right after
00:48someone with a regular nose, your brain gets confused.
00:52Suddenly a normal nose can look as huge as Pinocchio's.
00:55The same goes for lips, eyes, you name it.
00:58Since our brains are always comparing each face to the one before, they end up turning
01:02these beautiful celebrities into exaggerated creepy cartoon versions of themselves.
01:08So, tell me, what do you see here?
01:12A horse or a seal?
01:13It partly depends on where your eyes land first.
01:17If you look at the bottom of the picture, your brain probably thinks it's a horse.
01:21But if your gaze goes to the upper right corner first, suddenly it looks like a seal's tail.
01:27But it's not just about where we look.
01:29Then, something even stranger is happening here.
01:33When our brains spot an ambiguous figure with unclear information, we basically see what
01:38we want to see.
01:40In one experiment, scientists showed this exact image to a group of people and told
01:45them that if they spotted a farm animal, they'd win a candy treat.
01:49Yum!
01:50But if they saw a sea creature, they'd get canned beans, which is kinda weird, right?
01:56The results showed that 80% of the people saw a horse.
02:00So they decided to switch it up.
02:02This time, whoever saw a sea animal would get a treat.
02:05When the motivation changed, can you guess what happened?
02:08More participants ended up seeing a seal in the second round.
02:12So yeah, it seems like psychology plays a huge role in how we interpret ambiguous images.
02:21We also have these undecipherable figures.
02:23I mean, no matter how hard you try, you just won't be able to fully understand the image.
02:30Take the impossible trident, for example.
02:32On one side, it looks like three cylindrical shapes.
02:36But on the other side, it seems like they merge into two rectangular parts.
02:40This happens because the vision center of our brains does a lot of its work subconsciously
02:45and automatically, interpreting the figure as a three-dimensional object.
02:51When we see that structure in 3D, it doesn't make any rational sense.
02:55It's similar to the Penrose Triangle.
02:57This triangle is physically impossible to construct in the real world, so we just can't
03:02figure it out.
03:06The next optical illusion is the negative afterimage effect.
03:10So look at the three dots on her nose.
03:12If you didn't guess it already, that's Jennifer Lopez, looking like an Avatar character.
03:17But don't worry, this eerie look is about to change right before your eyes.
03:21Keep your gaze fixed on those three dots right in the center of the picture.
03:25Don't look away, and don't blink.
03:28Alright, on the count of three, we'll switch to a blank white screen.
03:33But you have to keep your eyes wide open.
03:35Ready?
03:36Here we go.
03:371, 2, 3, bam!
03:40Can you see what I see?
03:41Yup, it's J.Lo, looking fabulous in her red outfit.
03:45Crazy right?
03:46But there's a solid reason behind this magic.
03:49Our eyes have millions of tiny light-sensitive cells called rods and cones.
03:55Rods help us see in low light and pick up things in our peripheral view, which can also
03:59be pronounced peripheral view, while cones are all about color, bright lights, and fine
04:04details.
04:05When light hits these cells, they get excited and send signals to our brains, where everything
04:10gets processed into what we actually see.
04:14But here's the catch.
04:15Cone cells can get tired.
04:17If they stare at the same color for too long, well, they need a break.
04:21That's when other cone cells step in to help out.
04:25Different cone cells are better at handling red, green, and blue colors.
04:28So when certain cone cells get fatigued, the theory of opponent processing kicks in, allowing
04:34other cones to take over.
04:36And that's how the color in J.Lo's photo magically appeared.
04:40Hey, look who it is!
04:44Einstein!
04:45Well, squint your eyes, or if you prefer, take a few steps back.
04:49Wait, is Einstein suddenly turning into Marilyn Monroe?
04:53This is a hybrid image, which is kind of like a mash-up of two pictures.
04:58It combines the blurry parts of one image with the sharp details of another.
05:03In this case, Einstein's image is all about thin lines and sharp contours, like wrinkles
05:07and strands of hair, while Marilyn Monroe's is more about the big picture, with those
05:12blurred shapes.
05:14When you step back or squint your eyes, those tiny details fade away, and suddenly, Monroe's
05:19face jumps out at you.
05:22The same thing happens here.
05:24At first, this woman looks kind of, meh, not happy, not sad.
05:28But if you squint your eyes a little, suddenly, she looks really mad.
05:33Uh-oh.
05:34Wow, what a twist!
05:37Here are Kim Kardashian and Timothee Chalamet's photos turned upside down.
05:42Did you notice anything strange about them?
05:45You probably didn't, but if you look closely, you'll see their eyes and mouths aren't
05:50flipped.
05:51This is called the inverted face illusion.
05:53It happens because our brains are wired to recognize faces right-side up.
05:57We process them as a whole and pick up on details really quickly.
06:01But when a face is upside down, our brains struggle to catch those odd details, like
06:07the upside-down features.
06:10This trick is known as the café wall illusion.
06:13And what's crazy about that is these bricks aren't crooked at all.
06:17In fact, the horizontal lines are perfectly straight and parallel.
06:21This image tricks our brains because of how we process contrast.
06:25The sharp black and white tiles next to each other create a visual conflict, making our
06:30brains think those lines are bending.
06:33But if you switch the colors to something softer, like pink and blue, the illusion disappears.
06:39The softer contrast doesn't mess with our perception the same way, so we can see the
06:43straight lines clearly.
06:45And there's something else.
06:47Check out the layers of mortar between the bricks.
06:49Yep, those gray lines.
06:51The distortion only happens when the brightness of the mortar is somewhere between the dark
06:56and light tiles.
06:57So if the mortar is too dark or too light, the illusion fades away.
07:03Poof.
07:05These strawberries are red, right?
07:07Wrong.
07:08In this case, the strawberries aren't red at all.
07:11They are gray.
07:13This magic happens because of something called color constancy, which is our ability to recognize
07:18the color of an object regardless of changes in lighting or surroundings.
07:23In this experiment, all the red pixels in this photo were swapped out for gray ones,
07:28and we can prove it by zooming in.
07:30It only looks like there's red in this picture because the background is blue.
07:34Our brains think that the light source has some blue in it, and then they figure out
07:38the color of things by discounting the color of the light source.
07:42When your brain takes those gray pixels and subtracts out that blue bias, you end up seeing
07:48red.
07:49Interesting, right?
07:50The same thing happens with the dress.
07:53If your brain sees the lighting as a bit yellowish, it tries to discount that golden glow, making
07:58you see the dress as blue and black.
08:01And if your mind thinks the background is darker, it discounts those bluish tones, and
08:06suddenly the dress looks white and gold.
08:09So what's the real color of the dress?
08:11Well, in this case, it's actually black and blue.
08:15But let's wrap this up before we dive into that never-ending debate again.
08:22That's it for today!
