- Oh my god, yes! This is what I'm here for.
(laughs) Yes! - See, that is art!
♪ (upbeat techno intro) ♪
- (FBE) Today's episode might be a little confusing,
because you're gonna be looking at some crazy optical illusions
that will bend your mind. - Okay, that's fun. I like that.
- (Billie) Pink and white.
Pink and white. - I watched her whole story of this.
It's pink and white. - It looks pink and white,
but it's not pink and white, is it? - Is it not pink, Billie?
Whaat?! Wait, I'm wearing pink. - I love her so much,
but I have no idea how she doesn't see that.
It's literally pink and white. - I get what she means,
because when you hold it in a different light,
there's a blue hue. - (FBE) So, this post
from Billie Eilish started quite the debate online,
seeing as her shoes are apparently mint green and white,
not pink and white. - Yeah, I definitely don't see it.
I see pink and white. - Mint green. So, there are people
that see that as mint green. - It's not, though.
I think she might be colorblind. - (FBE) All right. So, how confusing
did you think this was? Scale of one to five.
- I'd give it a three. - Two. It's not that confusing.
- One. I think it's easy. It's pink and white.
- Give it a one. I don't think that's super confusing.
- Three. It confused me enough to say that one color
was another color, so that's pretty good.
♪ (tranquil music) ♪
- Uh, wait. Wait! Wait!
- It's just like, I don't even know how that makes any sense.
Oh my god, yes! This is what I'm here for!
(laughs) Yes!
- Okay, what the heck? I'm trying to figure it out,
but I can't see what would make it literally change colors.
- I'm gonna assume that it has to do with the lighting.
- Oh, man. That one was awesome. - That was confusing,
because I was trying to figure out, like, how does that work.
- See, it's all about the lighting. The Billie Eilish video
confused me with the lighting. This one was amazing me
with the lighting. I'll put this one at a two.
- One, since you can easily control that.
- It's all about light shading, so one.
- Three. It wasn't super mind boggling,
but it made me think a little bit. - Four, because I think if I sat here
and thought about it for a while, I would be able to understand.
But at first, it's just kinda like, "What the heck?"
- Ahhh, this is trippy. - I don't see anything that's weird.
Am I supposed to think it's changing or something?
- I know the lines are all different colors in the back,
but I don't see the illusion. - I see circles of the same color
being crossed by different-colored lines.
I've seen it before, and I know exactly what's going on.
- I see the balls with a bunch of different colors.
Their same color's going through them.
- (FBE) Actually, the balls are all the same color.
- Oh my goodness! Oh my goodness! You're so right.
- Wait, they are! Oh my gosh!
That is so cool! I didn't even think about that.
- I can't look at that. I can't. This is a five.
- I'll give that one a four. It's up there with that last one,
because I didn't know exactly what was going on.
It tripped me out that much. - Definitely one,
'cause I've already seen it. It doesn't mind fool me at all.
- That's a five for me. That took me forever.
Literally, it took me too long. - I'm gonna say a three,
'cause it's kind of confusing, but if you really look at it,
I feel like you could figure it out.
♪ (tranquil music) ♪ - Oh, dude. These are awesome.
I think I've seen a video like this. It's like the portrait's age
or something. - See, that is art! That's art!
- That's cool.
- That's so cool. So, it gets older the more
that you kinda... Cool! Okay.
- It's like one of those things you see in books, where it's like,
you hold it at a different angle, you'll see different things.
- I think I might have seen that on YouTube or TikTok.
I have seen people take a picture and just cut it up
in little strips and stuff, and then they rearrange the strips,
and then they have a bunch of little pictures.
- I would give that a two, because it's not an unknown concept,
so I feel like you would be able to figure it out.
- Maybe a three? - Five. 100%.
- Five just solely based on the fact that it's the coolest one.
- That one wasn't super confusing to me just because I've seen it,
so I'd give it a two. But I appreciate the art.
- Oh, wait. What is...
Okay, this is gonna take me a second, 'cause that chain can't be
holding up the whole ta-- I don't know how the chain
is holding it up. - Oh! Oh, wait!
I didn't even see the chain in the middle.
The top part is what's confusing me. I don't know how they did that.
- I see a piece of wood maybe-- I think that's what it is--
being hold just with chain and a little bit of steel.
I think it has to do with physics and all that.
- People, when they first look at this, obviously,
the first thought, "Oh my god. They're regular chains.
How is it standing up?" They're not regular chains.
- I've seen this image floating around Twitter.
The only way this could ever work is if those chains
aren't actually chains and they're just stiff, right?
It's gotta be perfect enough to where the chains are holding it up
or it's just images taken before disaster.
- So, this is not sorcery. It's called tensegrity.
Tensegrity structures are designed so that each member is subjected
to only pure tension or pure compression
to maintain stability. So, basically, the cable members,
they take the tension in the structure,
and the struts carry the compression. It's all a very confusing way
to say, basically, this table is just physics.
- Okay. Yeah, that does not make sense to me.
You have to be really smart to design that.
I would never be able to do that. - Oh my god.
Some next level engineering, though. - Probably give it a three,
'cause it does look really cool, and I still don't know how it works.
- Maybe a three. - I have to give that a five,
'cause that's confusing. - Five, 'cause there's just no way
you'd ever be able to figure it out without the explanation.
- Five. I was really confused. Even when you explained it,
I was still trying to figure out how they would do that.
♪ (tranquil music) ♪
- That-- what?
- That is so cool. I don't know.
I don't know how they did that. - See, that one I have no idea
how that works. I just wanna say it's a bunch
of mirrors in the pyramid, but I have no idea.
- Is it four separate chambers, where you just are viewing
a different one on each side of the pyramid,
but the glass kind of makes it look so it looks like one?
- (FBE) You got it. - That is so cool, though.
That's not something you expect to see when you walk up
to one of the sides. I'm sure you see that across the room
and see something, and then try and walk up to it
and see something completely different,
and be like, "W-wait, what?" (laughs) - (FBE) Yeah, right?
So, you are correct. This final one is created
by using double-sided mirrors, so with the large four-sided pyramid,
there are four different rooms on each side.
Each room contains a different stage of building a house.
- Gotcha, gotcha. I feel kinda smart for that.
- That's not that confusing when you really think about it.
But I think when you first see it, it's also just like, "Whoa.
How do you do that?" - I'm gonna give it a four,
because, yes, I'm confused. - That's a five.
- That looks really cool. I'd probably give that a five.
- Three. It's moderately confusing. I think if you think about it,
you can understand, like, that makes so much sense.
- Five, just 'cause it blew my mind. I loved it.
- (FBE) So, overall, what'd you think about these illusions?
- They were pretty neat. - I was honestly surprised
at how a lot of them kind of blew my mind.
- I really enjoyed 'em. Yeah, there were some new ones
in there that I'd never seen before that I really liked, so that was cool.
And it's always fun to save these for later,
you know, show 'em to other people, see what they think.
- Thanks for watching this episode of Teens React.
- Which illusion stumped you? Let us know in the comments.
- Bye! - Hey, guys. It's Sierra,
React producer? I guess if you were
pretty confused by this episode, then you should go ahead
and subscribe? I don't know.
I'm pretty confused. Bye, guys!
