- That's a lot of talent. I can barely juggle two balls.
(record scratch) Don't put that in there!
- (Presley and React laugh)
♪ (upbeat techno intro) ♪
♪ (playful music) ♪ - Ooh.
- What?! - What? What?!
- Is there someone behind him? - What's going on right now?
'Cause I swear he has three hands. - Oh, I can't tell.
That's actually hard. - Does he put it in his mouth?
I don't know. - That's just juggling, right?
- Oh, no. - That must've been reversed.
I didn't like that. That kind of scared me a little bit.
- That's the kind of video you think about five days later,
and you're like, (laughs) "How did that guy do that?"
- I think it's moving because the colors are changing.
- How do you find that you could do that?
- What in the world made him think, "Let me try this trick,
where I bounce three boxes back and forth
and make it look weird"? (laughs)
- Weird skill, but, you know, skilled nevertheless.
- It's almost haunting. - It's a little haunting
to me for some reason. It's a little spooky.
Noooo. - Ooh, that is cool.
What is that? I don't understand what that is.
- (whispers) Oh my god. (chuckles) - This one's trippy.
- Ohh, I see what she did. That's makeup.
- Ohhh, yeah! Oh my god. - Holy cow! This person's talented!
- First of all, she has so much talent being able to paint her face
so realistically. - I can't imagine how she does that.
- That's straight talent right there. Bro, get them-- they deserve
to be doing makeup for, I don't know, whoever the [censored] they want.
- What? There's like-- what? - (laughs)
- (React) Do you see what's going on there?
- I'm really trying to. - It looks like a baby's
on his back, but also not. I can't see it. I can't see it.
- That the child on the back of an adult,
but where's the child's head? - Maybe it's a life vest?
- Oh, I know. - Over the years, I've seen
a lot of these, so that's just a baby,
and the baby's head just somehow matches his head perfectly,
which is kind of crazy. - Oh, I see. I don't know
if this took too long, but I see it now.
Well, I think, like, right behind the profile
of the adult, is the side of the child's head.
- WHOA! I see it now right when you put your cursor over it, the line.
- Since they have the same skin tone,
it kind of blends in so it looks like they're just--
like the body's just the backpack, but the kid's actually--
his head's in front of the head.

- "Are you thinking what I'm thinking?"
No, I'm not.
- Oh, the floor or coffee table? - Interesting!
- I immediately thought floor. - If he didn't write that,
I think I would think it's the floor. But now that I read that,
now my head hurts. - I thought it was the floor!
I'm gonna go with coffee table, though.
- Oh, wo-- oh, it's like changing in my head.
- And all I'm thinking is that it is a coffee table.
- I've seen this before. I still don't know which one it is.
- I wanna say it's the floor. - (React) You're correct.
- Nice! Oh my god.
♪ (suspenseful music) ♪
- Okay, focus on it? - (React) Mm-hmm.
- Can't blink, huh?
My eyes are starting to hurt.
- (gasps) - Whoa!
- What'd you do? - It's normal colors.
- Boom! - Tell me you did that please.
- I was like, "Okay, I get a green field and what?"
And then I blinked, and it was gray! (laughs)
- (React) Yeah. - Whaat?!
- When you stare at a negative for a while, and then you look
at a black and white, the colors kind of reverse itself.
- I like that one.
- Ooh. - No, they are moving. What?!
- Shut up. - (snickers)
- That really hurts my head. - They're moving.
- (React) They're not moving. - They're freaking moving.
- How? - That-- no.
That one, I don't get at all. - (React) You don't get it?
- That's sorcery. Sorcery. No. They're like 100% moving.
- It looks like there's a way down. I only see a way down.
- I see a way down.
- Hmm.
- (React) I want you to follow each step down.
- Oh. (gasps) Oh my god!
- Ohhh! Ohhh! - Ohhh.
- I see where it gets kinda weird. It's that third step.
- It's the stairs. In the middle, it kind of looks
like they flip a little or turn a different direction.
- It almost looks like it's buckling.
That's so weird. - I feel like I'm seeing it
so it goes down like this and like this,
but it changes depending on your perspective. That's cool.
- (sighs)
Ah, my head hurts again!
- That must've been like a gelatin substance, right?
- Is that just water? - It's not syrup.
- What the [censored] is that?! - That's real-time?
It looks like slowed down water. - Is this slowed down?
- (React) No. - It looks nice,
like I wanna drink it. - Oh my gosh. That's so cool.
- Wow. - If you put your shutter speed
super, super low, you can get that kind of effect on a picture.
- (React) You actually nailed. It's a shutter speed trick.
- "You only hear the word you are reading."
- (React) Which one did you hear? - "Green needle."
- I heard "green needle." - (React) Okay.
- "Green needle." - "Green needle."
- Do it again. Do it again. I heard "brainstorm."
- (React) Okay, so you looked at "brainstorm."
- Yeah. - (React) All right.
So, for this one, I'm gonna rewind,
and you're gonna look at the other one.
(distorted speech)
- Ah! (laughs) I heard "green needle."
- What in the everloving [censored]? - Now it said "brainstorm"!
- I got brainstorm. That's cool. - That is so weird!
- No. (chuckles) No, I still hear green needle.
Is that crazy?! Please, one more time. I'm so sorry.
- (React) Yeah.
- Oh, I hear it! I hear it! There it goes!
(laughs) Brainstorm. - (React) You got it?
- I hear it, yeah. I hear it now.
- I feel like I just need to go take a nap at this point.
My brain has worked too hard for the past 15 minutes.
- I'm still scared from that last one.
Every time, it was what I was saying in my head.
And I genuinely wanna know the science behind that.
- I feel kind of enlightened. I feel like I've learned something.
I feel like there's a lot of different things
that I didn't know could contribute to just illusions in general.
- The funnest one, that one I liked the most,
that was the most fun was the photo that went black and white
that was probably inverted colors, I would assume,
and then the color changes. That one was fun.
- Brains... they trick us. They trick us.
They deceive us for sure. - (React) Which one
was the most confusing? - Oh, the faces.
I just couldn't figure out what is real and what isn't.
- You can convince yourself that something is different
just with your mind. And it just-- your mind can control
some of your sensory experiences,
which is pretty crazy how powerful the mind is.

- Wait, you changed it, though! You changed it just then, right?

the baby's head was missing. - I hate it. I hate it.
