- What the frick? No.
- It just really messes with my mind.
I don't know. I can't look at it any more.
♪ (upbeat intro) ♪
- (FBE) So, are you ready of us to mess with your head?
- Oh no. What the heck?
- (FBE) Because we have some gnarly optical illusions
for you to check out. - Yes.
I love optical illusions.
- Yes, I love optical illusions. I literally look at those
all the time in my spare time.
- (FBE) We're gonna show you ten of some of the more
popular optical illusions from around the internet
and just see what you think of them.
- Oh, I'm excited.
- You know what's cool about these probably,
is that they're gonna involve a lot of geometry.
That's dope.
- "Motion Pareidolia. Please observe the up
and down motion."
- A bunch of dots. "Did you see up and down
motion until the end?" Yeah.
- "Only the first five frames had up and down motion.
The last five frames were purely random."
So they were moving, but just not up and down?
- "As you view the next clip, think you yourself:
'Right, left, right" Okay.
They all look random.
- "Now, think to yourself: 'up, down, up, down, up, down'"
I just see it moving a bunch of times,
but it's between one picture and the other picture.
- No, it was moving up and down every time I said "Up and down."
- (FBE) This is basically your mind creating
the illusion that you wanna see. - Exactly.
How am I gonna know if it's up or down?
For real, how am I gonna know?
- So, on the side, I see three little
Pac-Man creatures.
- A little Pac-Man triangle. Three triangles.
Does it move?
- I see circles, not semicircles.
I see pizzas with a slice taken out of them
and then I see a Star of David.
- It makes an image using the negative space
of a black triangle like that, but there's actually
no triangle at all. Our mind learns to fill in
the gaps, so we perceive it as a triangle.
- (FBE) So, for this one, there is no black triangle,
but the absence causes your brain to complete the shape.
- What? There's two big triangles,
one's white and one's black.
- I think that's it's just three circles,
then a white triangle, then they put a black triangle
and made it look like there's no triangle there.
- (FBE) How many different colors can you see in this photo?
- This is such a trick question. I'm looking at it
and I'm like, "How many colors do I see?"
My eyes deceive me.
- How many different colors? There's three.
- They keep moving. Pink, blue, and orange and green.
- So, there's definitely the orange and the pink
and then there's a blue and a pink, but when
the blue and the orange are together, the blue
looks more green.
- (FBE) So, what may appear to be four colors
is really only just three colors. The blue and green
are actually the same color. - Wait, hold up.
Hold up, I think you're right. What the frick?
No.
- The colors are just making it look different.
I see.
- That is what it is. Got you, but it's because
of the contrast, pink on this side
and orange on this side, the shade looks different.
See, this is really interesting.
- (FBE) So, for this one, the closer you get
to the image, the wider and brighter the white spotlight
seems to get. - Okay.
Oh my God, that's cool. I like that one.
- That is so interesting. Why is that?
- It looks like it's glowing. I feel like there's
a train coming towards me.
- It does do that. When I'm here,
it's almost to the edges and then when I'm back here,
it's only in the center.
- Oh my gosh, it does. No, okay, no.
No, that's dumb.
- As I get closer-- oh yeah, it does.
But it's not-- it's just 'cause of my focus.
This is not really that dope. Come up with some cooler
optical illusions.
- Okay, sort of blurry. Sort of looks like
I'm looking through a foggy glass.
- (FBE) So, pick a spot in this image and stare
directly at it. The longer you stare,
the more the rest of the image disappears.
- Everything's so blurry. Oh, it looks like it's shrinking.
Oh, that's cool.
- I feel like that kinda didn't work for me.
I'm gonna try to focus on something else, though,
because the blue thing is first of all,
it's more prominent than the others,
so everything already kinda disappears compared to it.
- It's going away. It's going away.
It's gone, it's gone.
- Oh [bleep], yeah. It happened.
Wait, hold up. That's trippy.
- It is definitely disappearing. Will it stop?
Then when you blink, it comes back.
- What? That's so weird.
The bottom half is gone. If I blink, it's back to normal.
That's so weird.
- (FBE) So, if you blink while looking at this gif,
it almost seems to reset. If you quickly blink,
you can see numerous random patterns within it.
- That's trippy, actually. I just made my eyes
become a strobe light.
- Oh my God. It looks like the circle--
there's a circle in the middle. If you blink really fast,
it looks like the circle moves.
- When I blink I see a circle in the middle,
kinda like a target. You know the Target logo?
It's kinda like a bullseye.
- It's so cool. This one's cool.
Damn, I could look at it for a while.
It's kinda trippy.
- Seems like something I'd wanna, you know--
in those adult coloring books, draw, color in.
- It just really messes with my mind.
I don't know. I can't look at it anymore.
It's giving me trypophobia.
- This is one of the stair things that's not really...
Okay, gotta figure this out.
- This is a mind [bleep]. I see it, I see it.
Okay, I can't tell if it's two blocks laying next
to each other, or two blocks one on top of each other.
- It's one piece of wood. Wait, what?
I'm confused what this is. Oh my--
I see it now. It's sideways.
- It's supposed to look like-- if you like from down here,
it's two blocks on top of each other
with the nail going this way,
but if you kinda progress up to where the hand is,
it looks like two blocks next to each other
with the nail going this way.
- (FBE) This is a real life photo version of the sheer stairs.
- Yeah? How did they do that?
- You're making me question things about my brain
I shouldn't be questioning right now.
That's really trippy though.
- (FBE) Which of these two monsters appear larger?
- Are you serious right now? It's gonna be one of those things
where you put them next to each other and they're
the same size.
- The one that appears larger is the one that is chasing
and the one that appears smaller is the one
that's being chased, but I feel like without
the tunnel, they'd be the same size.
- I think it's just the perspective that makes that one seem
a lot bigger than that one, 'cause that one has
a bigger shadow and it's coming from the tunnel
when the tunnel looks smaller.
- I bet you they're the same size. Are they the same size?
- (FBE) Well, they are both the same size.
- Oh, okay. That's weird though.
How does-- that one looks so much
smaller than that one.
- What you're doing is you're comparing
the drawing of that guy running to the background
which are those bricks. The environment's changing.
It's not-- oh my gosh.
- "Ambiguous Garage Roof." Looks cute.
It's so tiny.
- ♪ (piano) ♪
- So, I guess it does bend down in the mirror,
but it looks like it bends up. What?
Oh my God, it's... How is that possible?
- Ah, I get it. Okay, so it looks like it's flat
because of the angle we're at, but then you turn it around
and it is shaped very odd.
- Maybe it's something with the mirror.
- Flip it over.
- Oh, no wonder. You see, look.
This one's cool. I like this one,
'cause he's explaining "Oh, this is how we did it though."
- That's weird. Even after knowing
that you know the trick, it still tricks you.
When it turns around, it still looks like it's just
a curved line. That's crazy.
- (FBE) So, do you see the white and black
rope shape that spirals downwards?
- Yeah, I do.
- (FBE) Those are not spirals, but actually separate circles.
- Oh yeah, I see it. Wait, they're all separate?
- What? I need to find one.
- But it looks like it connects. It looks like it--
oh, no. 'Cause if I just follow it
trying to see it connect, it's not going down.
- It's the pattern behind it, which is what makes
your mind see a spiral and it's so weird,
'cause it really looks like it's going clockwise.
- Oh my God, they don't connect. They don't connect!
Ah, that's tripping me out. This big one,
it looks like a circle, but all the rest
look like they connect. How much time do you
have to have to thoroughly think, "I'm gonna make
this optical illusion to confuse people."
Oh my God.
- I just need to stare at nothing for a while,
like a blank wall, but then I'll start seeing things
in there, probably.
- What you think that you are visualizing
in the world can be completely different
than what's actually there, too. Our brains are scary.
They like to work in the most efficient way,
so they take the smallest amounts of information
and they try to put it together in this quick,
"Okay, I know what I'm seeing." But you're not.
You don't know what you're seeing.
