(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.

And then we're going to try a test with a TV.

We have our paramedic here.

- Whatever you do,

do not try this at home.

No no no no no. - No no no.

(techno music)

(beep)

- We need to test your theory about the hair being able to

hold the weight of two elephants.

We're gonna start it off kind of easy.

We're gonna use this frying pan.

One of you can help put it through the hole.

(laughs) I'm sorry.

(laughs) - So this is really good

because this is a lighter object.

- [Chrissy] Wow, it looks like you've done this before.

- Absolutely.

- This is our first test.

We're just starting off small, little frying pan here.

You ready? - Little frying pan.

- Should I get, like, a little, like a little clock start?

- Swing. - A little tik tok?

- I don't know why we're all swinging

but we're going to swing together. (laughs)

(grunting)

- That's good, you did it! - Yay!

- Yeah, swing that pan.

How did we go from a frying pan to a TV?

- It'll be fine, you'll be fine.

Oh my God, I am so scared.

- Okay, we'll stand up.

(laughs) Stop.

- Should I hold your hair?

- [David] No no no, don't hold anything.

Take your hands away from the TV, just don't move

- Oh my God, I'm so scared - [David] Just don't move.

I'm going to gently let it go.

- Watch your feet, when she (chirp), oh (chirp),

I don't wanna do this.

- I'm still holding, I'm still holding it.

Don't worry.

- You're not! Oh!

- One finger at a time. Just one finger at a time.

(grunts)

- [David] Okay, there, There we go. Don't touch it.

- [Selorm] Oh my God!

- Yes! - I'm sweaty.

- I'm sweating too and I'm not even doing anything.

- Good job. That was good.

- Bye.

- Alright, dude.

Now it is officially time.

I'm going to go on this little towery tower thing,

and I'm going to throw my hair over it,

and we're going to add a few little rope inches

on to the end so that way I can, like,

get the full Rapunzel experience.

And then I'm gonna see if I can lift

110 freaking pounds!

- [Selorm] I'm really scared for you.

- Why?

- I was freaking out a lot during that TV part.

- You know, so was I.

(laughs)

- Selorm! We're here! - Oh my god.

- Do you like my fake (chirp) tower?

- Yes, you look like a beautiful princess.

Just like, "Hello, my people."

- Clearly we already know the strength of hair.

Now it's about testing my strength.

Okay, I took some safety precautions.

Got some little glovey gloves with some little grippy-grips.

Like, I'm already tired.

- How are you already tired? - Because I'm stressed.

Alright. I'm gonna get a little leverage here.

- You can do it!

One, two, three, go pull pull pull pull pull!

(screams)

- [Chrissy] Oh God, I'm sliding.

- [Selorm] Keep pulling, you got it!

Okay, the chest is up. - How far'd I get?

- Well, you got the chest up and you got the head up.

- (scoffs) Okay, let me keep going.

- Okay, ready?
