  • - [David] Your scalp could be removed.

  • (screams)

  • - [Chrissy] All the little holes of my hair follicles

  • could bleed

  • - One, two, three, go!

  • (screams)

  • - [Chrissy] Oh God, I'm sliding!

  • - Welcome back to our lab-beaut-ory!

  • - I'm Selorm. - And I'm Chrissy.

  • Alright, dudes, here's the deal.

  • You (chirp) love Disney,

  • you (chirp) love drama.

  • Luckily, we love debunking,

  • so we're gonna get a full season

  • of Disney-themed drama coming your way.

  • What's up first, Selorm, tell 'em.

  • - When you think of the most iconic Disney princess hair,

  • who do you think of?

  • Rapunzel! Right, right?

  • - Yeah!

  • Let's just, like, deep dive into Rapunzel's life.

  • She's a teen,

  • she's trapped in a tower,

  • and her mom sucks, okay?

  • Her mom is basically a witch who kidnapped her

  • and uses, like, her hair powers to make herself look hotter,

  • a.k.a. younger, but younger doesn't always mean hotter,

  • like, don't follow beauty standards, okay?

  • The only way that she can get her mom up there

  • is if she throws her hair through that tiny (chirp) window.

  • Her mom's like, "Hey, let me up!"

  • She has, like, a little pulley.

  • She, like, latches it in there,

  • so she's all "boop!"

  • And then she, like, lets it go

  • and then her mom literally, just like,

  • puts her foot in it and then Rapunzel is like

  • And then her mom is like, "I suck, hey!"

  • And then they chat and hang out

  • and that's, like, her only social interaction for the day.

  • That's (chirp) up. - That's real (chirp) up.

  • How does her neck not break, actually?

  • - Like, you think about, like, all your teen probs

  • and you're like, "Rapunzel's going through it."

  • So we know Rapunzel's a boss (chirps),

  • so we need to figure out

  • if you actually can lift a human with your hair

  • through a pulley system.

  • We're going to need to talk to a physics expert,

  • because I don't know anything about pulleys.

  • - Nope.

  • - And we're going to have to get our hair done.

  • - But I just got my hair done, so this is something for you.

  • - Great.

  • - For Rapunzel.

  • - Yeah. I'm doing this for Rapunzel.

  • Also I know you love your mom,

  • but, like, she's (chirp) up, don't listen to her.

  • I know you don't have Internet, and you can't see this.

  • Her only friend was a lizard man. That's so sad.

  • Love you, 'Zel. This is for you.

  • Flynn's hot.

  • - My name's Jenna Ervin,

  • I'm the science program specialist,

  • at Kidspace Children's Museum in Pasadena, California!

  • - So will you tell us the physics behind

  • Rapunzel pulling up her mom

  • with just one little pulley?

  • - So what we're basically looking at are two masses.

  • One mass is Rapunzel's mom and one mass is Rapunzel.

  • And they're being connected over a pulley by a single rope.

  • - So you think that hair can lift a human?

  • - Yeah, oh, easily.

  • The hair isn't the problem, it's the neck breakage.

  • - Oh, (chirp).

  • - [Jenna] So her neck wants to stay on her body

  • vertically, but if your force is moving horizontally,

  • it's going to snap it that way.

  • - And then you would die.

  • - Yeah. (laughs)

  • - So use the leverage of your arms

  • and the leverage of your, like, legs and torso

  • to help pull that in.

  • - So do you think that this is possible?

  • - I think it's possible.

  • - Okay. Without dying?

  • - Um

  • - (gasps) Oh my God.

  • It's David Dang!

  • He fixed that sword situation of a haircut.

  • Let me just lay this out for you,

  • like, I want to be Rapunzel.

  • I want a 70-foot-long, blonde, gorgeous train of hair

  • that I can, like, whip around,

  • like, pull people up with

  • - And a yacht attached to that, too,

  • while we're at it, right? (laughs)

  • - Let's just pull the yacht in.

  • Hair can actually hold up to twelve tons.

  • - Wow. - So, doo doo do doo!

  • Twelve tons is about the size of two elephants.

  • - What?

  • - Seventy feet of hair is impossible.

  • - Why? - Because you would have

  • to be growing your hair

  • at a half an inch a month

  • and be anywhere from a 125 to dinosaur years.

  • - So what are some alternate solutions

  • to get that Rapunzel hair vibe.

  • - So we've created a head of hair for you, 60 inches,

  • which is five feet.

  • She is right here! (gasps)

  • - She keeps coming apparently.

  • - Oh! - That's so long!

  • - Oh my God, this is heavy.

  • This feels like my dog.

  • - [David] So it's synthetic hair

  • to kind of mimic the strands of hair on your head.

  • - Well, I already feel like it's a part of me.

  • - I got extensions put in my hair, like, multiple times

  • so I know that this is a process.

  • Chrissy, this is actually going to be sewn into your hair.

  • - So let's talk about the dangers

  • of what this hair could do for you, right?

  • Your head could snap at any moment.

  • Your edges could get snatched.

  • - [Selorm] Snatched right off.

  • - Your scalp could be removed.

  • - What?! - All gone.

  • - My scalp?! - Full on gone.

  • Full on gone. Gone, girl.

  • This whole entire process is probably going to take

  • anywhere from four to five hours.

  • - Oh my. - That's short, girl.

  • - [David] Did you eat lunch?

  • We're going to sew it in track by track

  • and the reason why were going to do that

  • is so your head doesn't move.

  • - Alright, um, I'm going to get some snacks,

  • and let's do this.

  • Thank you, guys.

  • This is sweet. - You're one of us.

  • One of us, one of us.

  • (upbeat music)

  • - [Chrissy] Selorm, are you ready to see me

  • for the first time?

  • - I'm ready, my hands are over my eyeballs.

  • - [Chrissy] Okay, don't looky yet!

  • - Okay. - Don't look...

  • - Don't touch me with the hair, I'm going to freak out.

  • Oh my God, no! (laughs)

  • (gasps) Oh my gosh!

  • You're a princess!

  • - I'm Rapunzel!

  • - Yo! This hair is as long as my body.

  • How does that feel? Are you not, like, struggling?

  • - Um

  • I am. - So today, we're gonna

  • test the strength of your hair

  • and you're gonna be lifting a human.

  • We couldn't find a human who would sign the waiver,

  • so we have a dummy.

  • - Oh. That's fine.

  • - Are you scared at all? - Yeah, yeah I am.

  • You know, here's the thing.

  • This is sewn into my freaking head.

  • - That's your scalp now.

  • - Meaning if this little dummy man comes along

  • and I drop it, all 110 pounds are gonna be like vvvpp.

  • Meaning I could break my neck.

  • All of the little holes of my hair follicles

  • could bleed profusely from my head.

  • Rapunzel made it look so easy

  • and I haven't even done anything yet

  • but I'm, like, already sweating.

  • - Okay, well, before we do anything with the dummy,

  • because that's dangerous as (chirp),

  • we're going to try a test with a frying pan.
