on the Magic School Bus [Music] Oh, I hate the cold! Cold is for wolves and polar bears, not kids, right, Arnold?

Right, Arnold? No, I like the cold because it means we get hot cocoa! [Music] I'll save you a

seat. One hot cocoa, please. Hello, Miss Frizzle, it's my weekend cafeteria duty. Arnold, one marshmallow or two?

Two marshmallows, please! Oh, careful, Arnold! As my great-grandfather Nicholas used to say, "It can hurt a lot when the mug gets

hot!" I'd go to the ends of the Earth for this drink. What a provocative [Music] idea! Not too hot now, just warm and lovely.

Hey, AR! Hi, Arnold! Great hot cocoa today! Wanda, saving a seat does not mean giving it to Harry

Arm. Yes, sir! The beautiful thing about hot cocoa is that it can be enjoyed anywhere. Want to sit over there by that

broken window? No way! Bird, it's too cold over there! Not when you have hot [Music]

cocoa! Oh, at last, you're [Music] mine! It's cold! Where did all the hot go? I thought he'd never ask!

[Music] Uh, you had to ask, didn't you, Arnold? You know I hate the cold. I just

wanted to know where the heat—my hot cocoa—went! A burning question, Arnold! And what better place to study heat than the

land of ice and cold? You mean we're in the Arctic? Exactly! The Arctic! That's one of the

coldest places on Earth! At my old school, we wore jackets when it was cold. Jackets, of course! Why didn't I think of

that? Uh, Miss Frizzle, aren't these a little thin for the Arctic? Well, let's see what else we have in stock. Wool

jackets? Nope. Down-filled parkas? On order. Sheep-skinned flight jackets? Out of stock!  Whoa, look out!

[Music] Whoops! Come on, bus, do your stuff! The engine's frozen and the heater's cooling down already! I knew it!

We've been frozen again! I heard that, Tim! And I like [Music] it. Oh, bad, bad, bad, bad! Kea, shut

the window! You're letting all the heat out! According to my research, the Arctic temperature can drop to 100° below zero.

Arnold, you got us into this, and I'm going to get you out! How I was hoping you wouldn't ask

me that! Uh-oh. Looks like some of us are losing heat faster than others. That's right, Liz is cold-blooded. She gets most

of her heat from outside her body. Look, I think she's trying to point to something. Don't worry, Liz, I'm

warm-blooded. My heat is your heat. Maybe she is pointing at this trunk. Hey, excuse me! All right, ski goggles? Oh, not quite.

Ralphie, these aren't ski goggles; they're heat peepers! Heat peepers? What do they do?

Whoa! Is it just me, or did Ms. Frizzle get frizzier? That's not hair, Ralphie;

it's some kind of stuff moving away from her body. If that's the case, then moving heat means losing heat, and it's going

fast! It's going right out of the bus and out into the cold!  Kea, oh please, keep the window

shut! Now I understand. That's where the heat in my cocoa went—out the top and through the metal

mug! Oh, you got it, Arnold! Heat is always on the move, and it's moving out of our bodies.

We need to find a heat source. Maybe there's a heater or something in here. Hey, wood! We can make a fire! A way

to go, Arnold! When you're hot, you're hot! Ooh, that's much better! Yay, warm at last! But for how long?

As long as the wood holds out, which won't be much longer. Whenever I've got a tough problem to

solve, I break up the old brain cells with a cup of hot lemon water tea. That gives me an

idea! What about breaking up the wooden trunk in the bus and using it for more firewood? Hot idea! Let's stoke the

oak! Stand back! Hot water bottles! Wait a minute! Hey you guys, anybody want a heat source?  Deduction, Carlos! Hold them

open! Wow, look at all that heat going into the hot water bottle! Hey, I can feel the heat moving

into my body! Hmm, if we can move the heat from the fire into the hot water bottles, what if we move the hot water

bottles onto the bus engine? The heat will move from the bottles onto the engine and it'll start!

Vroom! And once it starts, we're out of here! [Music] Yay! Too late! The bus is already out of

here, and so are Phaeb and Rallie! Rallie! Come back! We can't...

we floating away? At my old school, we never got stranded on ice flows! First we lost our heat, now we're losing our best

friends and the bus! Whoops! And I almost lost my hot water bottle! Make that cold water bottle! The

heat's gone! If we don't stay warm, we'll never save the bus or us!

Remember, every cloud has a silver lining.

I don't know about clouds, Miss Frle, but maybe if these jackets had some kind of

lining, the heat wouldn't move out so fast.

I think you're on to something! Da, can I borrow your book?

Uh, sure, Arnold. What are you doing with my book?

Sorry, Dorothy! Desperate times call for desperate measures! Since the heat moves

So easily through these jackets. Maybe we can slow it down by putting something in the way. Hey, it's

working!  The inspiration of insulation. We're going to be permanent ice cubes, I just know it!  Fee, what are they doing? Are

they trying to save us? Actually, they're stuffing paper into their jackets. They're doing... what? Wow! It looks

like the paper is keeping them warmer. He's not losing heat as fast as Wanda. Too bad we don't have anything to

What is it, Liz? The repair manual? Maybe they'll tell us how to unfreeze the bus, turn it into

Can I see it? Sure. Have you lost it? Our very surviv-

depends on what's in this book. You're right, I'm feeling warmer already. The paper's keeping my heat in.

Ralphie, keep cool, Ralphie! We'll save you! Keep cool! That's not the [Music]

problem. Well, we've slowed down the movement of heat by putting something in the way to block it. Any chance we could

find something warmer than these paper heat blockers?

Miss Frizzle, what if I told you that there was a fur

coat and a heat source due north? I'd say...

let me add it. Last one of the heat sources: a frozen egg, but I

Oh, that feels good! Oh, warm, warm, warm!  J as rfie would say...

does this heat source smell like a dead fish? Who cares! If we don't keep warm and save the bus, Ralphie may never say

anything again! Smells like a dead fish, feels like a hot breeze, looks like... yikes! A polar

bear! Yooo! Class, now you see us, now you don't! [Music] Where are we? How are we going to save

The bus? Now, I know... well, I don't know exactly. I'm working on it. Wherever we are, it sure is hot. Can we

get this heat source to the bus? It's certainly bear... is thinking about... then I better find out where the bus

is. Wait for me! I don't get it. We're in the middle of the Arctic. How did it get

to be so steamy? Well, let's check it out. The heat's coming out of the ground, and

it's still warm up here. You're right. It looks like the heat from the ground gets trapped by these

weird plants. What kind of plants are these, anyway? Hey guys, over here! I can see it! I can see the

bus! Kha, be careful! The heat's escaping through the hole in the roof!

This isn't a roof; it's polar bear fur! We're riding the polar bear express! We're on the polar bear! So, does the bear's hair work just like the paper

we stuffed in our jackets to keep the heat in? As my niece, Moon Valley, always says, "Like, for sure, for sure!"

Mfrle. I get it! It's the tangled hair that insulates the bear. Excellent observation, Carlos!

But how do we get out of here? [Music] Yay! This way! [Music] PRS. Where are they now? Phoebe, I don't

know, Ralphie. I can't see them. [Music] Anywhere. What was [Music] that? It seems like the ice flow is

shrinking. Shrinking as in getting smaller; as in breaking [Music] apart. That just about covers it.

[Music] Ralphie, at least we've been blown closer to the bus. Oh no! The ice is breaking

[Music] apart! Baby, we're goners! I know it! No more bad jokes from Carlos! No more

Field trips are no more! Friz, snap out of it!  R-selfie! According to this page, there should be some blankets, right?

Up! [Music] Here! Ew, gross! What kind of blanket is this? Looks like a fat blanket!

Hey, it may be gross, but that fat... uh, crap! [Music] Heat! We're done for! Scram! Beat it! Don't mean to be rude,

but you're too heavy. Wait a second. How do walruses swim in that freezing water? I don't know. Look,

there's hardly any heat coming off their bodies. I bet all that blubber just traps their heat, just like the fat did on your

hand. I got it! If it's good enough for a walrus, it's good enough for us! Hurry up, Ralphie! I'm telling you, it'll

work! There they are! Hey guys! Oh no! They've lost so much heat, they've turned yellow!

Come on, Arnold! You turn blue from the cold, not yellow! Believe me, I know!

Hey, hey! Come on over! We figured out how to keep the heat!

Yeah! [Music] Hang on, Phoebe! We've got to save them! I know! We'll jump in the water and swim

across! According to my research, you won't last more than 3 minutes in water this cold. Okay, then maybe not!

Never fear, Arnold! Where there's a Liz, there's a way! Hit it, Liz! [Music] We've been...

SL...actually, we've been blubbered! Good work, Liz!

Ooh! Now that we're messy, it's time to make mistakes, take chances, and get
