Some optical illusions can make celebrities look like they’ve swapped genders, and it’s all about the way we see faces. Richard Russell, a researcher, studied how the contrast in facial features plays a big role in making a face look masculine or feminine. For example, women’s faces naturally have darker eyes and lips compared to their skin, giving them higher contrast, while men’s faces have less contrast. It’s like a magic trick for your brain because it relies on how we’re wired to interpret gender through subtle facial details. Let's see if this and other optical illusions can fool your brain easily.

00:00Look who it is – the one and only Timothee Chalamet!
00:04Two things we know about his looks – he has a gazillion lookalikes in New York City,
00:09and he possesses an androgynous beauty.
00:11You wanna see some proof?
00:12Alright, let's zoom in on his face and focus on his eyes, nose, and mouth.
00:17Now let's erase his stubble and double this picture.
00:21On the left side, we'll increase the contrast between his eyes and lips and the rest of
00:25his face.
00:26On the right side, we'll do the opposite by decreasing the contrast.
00:31Can you see any difference?
00:32Does Timothee look more feminine or more masculine in one of the photos?
00:37According to a researcher named Richard Russell, facial contrasts significantly contribute
00:42to how we perceive male and female faces.
00:46Female faces tend to be more attractive when their facial contrast is increased, while
00:51male faces are perceived as more attractive when their contrast is decreased.
00:57What if I told you that Margot Robbie could be in the same room as you in just a few seconds?
01:02Trust me, all you have to do is focus on the red dot in the middle of this creepy image.
01:07In a moment – not just yet – I will ask you to look at your ceiling and blink super
01:12fast.
01:13Keep watching, and you will see Margot Robbie right above you.
01:17Wait just a little longer, and… go!
01:20Look at your ceiling and start blinking.
01:22Do you see Margot?
01:24If you did, let us know in the comments below!
01:28Optical illusions are all around us, more than we realize.
01:32Think about those crazy viral 3D billboards that look like products, animals, and other
01:38things jumping right in front of our faces.
01:41What is really strange about them is that we see those images in 3 dimensions, but we
01:46don't need those funky 3D glasses with red and blue lenses.
01:50The secret behind this trick lies in a popular optical illusion called forced perspective.
01:56Yep, it's the same technique tourists use when they want to snap that classic photo
02:01that looks like they're holding up the Leaning Tower of Pisa.
02:04Please don't.
02:05What happens is that our eyes, which are slightly separated, each see the world from a slightly
02:11different angle, which is known as binocular disparity.
02:14Our brains then combine those views to create depth in the images we see every day.
02:20So, 3D billboards are trying to copy that.
02:23That's why they always have curved displays with two faces.
02:27This way, animators can present similar images from two slightly different angles on each
02:32screen to create a 3D illusion.
02:37That's weird.
02:38Here we have half Anya Taylor-Joy and half Beyonce.
02:42But hey, were their photos taken from the front or from the side?
02:46The correct answer is head-on, since they're both looking straight at the camera.
02:50But because the photos are cropped into side-profile silhouettes, it totally seems like they're
02:56facing sideways.
02:57Wanna make things even weirder?
02:59Let's hide the photos and just leave two black silhouettes.
03:04Now what do you see?
03:05Two people looking at each other.
03:07Or a vase in the middle.
03:09This is a classic optical illusion called Rubin's vase.
03:13It was created around 1915 and is a famous example of an ambiguous image.
03:19It all depends on how our brains interpret the contours and the context of the image.
03:24If the context is the black color, you will see two people.
03:28If the context is yellow, you will see the vase.
03:31But there's no right or wrong here.
03:34Keep staring at the center cross.
03:36I know, I know, the image is sickening, kinda literally.
03:39But you've come this far in the video, so don't quit now.
03:43Just keep focusing on the cross for a little longer.
03:46On the count of three, we will switch it to a photo of Shakira.
03:50Ready?
03:51One, two, three, and… wow!
03:54Ok, Shakira's hips don't lie, but they're totally moving!
03:58This motion doesn't make any sense since this is a static image.
04:02So what's happening?
04:05This process is known as the waterfall illusion.
04:08It's basically a motion after-effect that happens when you look at a stationary object
04:13after staring at something moving in one direction for a while.
04:17The name comes from the same experience you get after watching water in a waterfall move
04:21in one direction for a couple of seconds.
04:24When you stare at something moving in one direction, like the water in a waterfall,
04:29your brain's motion sensors focus on that downward motion.
04:33But after watching it for a while, those neurons get a bit tired of seeing the same
04:38downward movement and become less sensitive to it.
04:41So when you finally look away, the neurons for the opposite motion, in this case upward,
04:47suddenly seem extra active by comparison.
04:51A similar thing happens here.
04:53Check out this dove.
04:55Even though the sky is red and looks kinda bizarre, the dove is pure white.
05:00But keep staring at it, and something creepy will happen.
05:04In just a couple of seconds, we're going to change the sky to white, and the dove will
05:08look strange.
05:10Are you ready?
05:11Here we go!
05:13Boom!
05:14If you are seeing what I'm seeing, the dove now appears to be red, more like a faint version
05:19of the red from the original background.
05:21This effect is called positive afterimage.
05:24And you wanna see something even cooler?
05:27If we keep flipping back and forth between the two images really quickly, the effect
05:31gets even stronger.
05:33Can you see it?
05:35Now look over here at this dot.
05:37This illusion is known as the stepping feet, and you'll see why it has that name in just
05:41a couple of seconds.
05:43What you see here are two feet, one blue and the other yellow, moving smoothly and quickly
05:48in a horizontal line.
05:50Now let's see what happens when we change this flat gray background by adding vertical
05:55stripes across the screen.
05:57Notice how it looks like the feet are taking little steps, one at a time, right?
06:02So why does this happen?
06:04It's all about contrast.
06:06When the blue foot passes over the white stripes, the dark blue against the bright white stands
06:11out, making it look like it's moving faster.
06:15But when it crosses over the black stripes, the contrast drops, which makes it seem like
06:20it's slowing down.
06:22The yellow foot does the opposite – it looks faster on black and slower on white.
06:27Now if we take away the stripes, there is no contrast shift to mess with our perception,
06:32and the illusion disappears.
06:35This optical illusion is the last one on our list, and there's a good reason for that.
06:40It can have effects that stick around for a long time, like hours, weeks, and some people
06:45have even reported effects lasting for almost 3 months.
06:49So are you ready?
06:51Close your eyes for a second.
06:53Great, now open them.
06:55Look at this image and keep staring.
06:58At first glance, it looks like a bunch of stripes, both horizontal and vertical, in
07:02the background.
07:03But these aren't just any black lines.
07:06If you want to experience the lasting effects, you need to stare at it for at least 3 minutes.
07:11So if you're feeling brave, go ahead and pause the video to set a timer.
07:16Next step.
07:17Look at this red picture.
07:19Focus on it.
07:20Again, to make the effect last longer, you should look at it for about 1 and a half minutes.
07:25Feel free to pause the video so you can stare longer.
07:30Now we have this green picture, which is very similar to the red one.
07:34Keep staring at it.
07:35If you want to test its maximum power, so to speak, pause the video and look for a minute
07:41and a half.
07:43Awesome!
07:44Now we come to the grand finale.
07:46We're back to square one with the black and white picture.
07:49Did the effect work for you?
07:51You might see red and green hues in this picture this time.
07:54But we promise you, we didn't make any color changes.
07:57It is all in your mind.
