-Hey there! How's it going? -Boop!
Hey, Boop. How do you take out a screw?
Boop.
Boop, boop, boop-boop.
Boop.
Boop!
Boop.
Bang, can you tap your head and rub your belly at the same time?
Whoa, I don't know.
I thought that was physically impossible and stuff.
Is this it?
No.
How about now? This is it, right?
Not like that. It's like this.
Whoa.
You're good.
Hello. Beep speaking.
I'm sorry, I can't hear you.
Hold on a minute.
Excuse me! What are you doing?
Cleaning up the leaves.
What? But there's no leaves here!
Yeah. Not anymore.
We got a Level Three coming in.
StoryBots! Oh, I got through.
I was starting to panic. I didn't know where to turn.
What's the problem, Miss Canteen Dinner Lady?
Okay. The problem, Bing, is I have to cook lunch for 300 students,
and my taco supplies arrived, but--
Tacos? All right, man.
Nothing like a tasty, hard-shell Mexican treat
with a little guacamole, lime, jalapeño…
Bang, I think Miss Canteen Dinner Lady has a question for us.
Oh, yeah. Sorry about that.
No problem, Bang. I get pretty excited about tacos too.
What seems to be the problem?
The problem is that my taco supplies arrived,
but today is only Monday.
Yeah, and?
The problem is no self-respecting elementary school chef
would serve tacos on Monday.
Tacos are for Tuesday.
It's an alliteration thing.
Why don't you put the supplies in that big refrigerator until Tuesday?
That's the first thing I thought of. But when I opened the backup refrigerator…
It wasn't cold.
Why don't you call someone with tools to fix it?
Ever tried to make something happen
in a resource-constrained state school system?
Can't say I have.
Let's just say it'd be faster if I fixed it myself, which is why I'm calling.
You want us to fix your refrigerator? That's not what we do.
Yeah. You've reached the Answer Department.
Yes, I understand.
I'm hoping you can tell me how refrigerators work so I can fix it.
Oh, well, that makes a lot more sense,
because I'm not very mechanically inclined.
Okay, who do we know who might be able to tell us how refrigerators work?
Tundra Tara runs the StoryBots Refrigadome.
Yes, great idea, Bing.
-That place is freezing cold. -Boop.
Bing, thank you. But hurry, I need to refrigerate these quickly,
otherwise there may be no tacos on Tuesday,
and we cannot have a Tuesday without tacos!
Don't worry, Miss Canteen Dinner Lady. We are on the job.
Answer Time!
Hi, StoryBots. What's in the news today?
You're watching StoryBots News on channel 22 and 2/3, WBOT,
with your hosts Story Storyberg and Bot Botson.
And now, a special report.
When dolphins sleep, half their brain rests at a time,
while the other half stays awake.
Row, row, row your boat Gently down the stream
-Merrily, merrily-- -Would you keep it down?
Half of us are trying to sleep!
Oh, sorry, left brain.
Mary had a little lamb
For crying out loud, would you shut--
Hi, StoryBots. Can you tell me about a dinosaur?
Yeah, here I go, here I go
No other dinos rock this crest that I got
See, it looks like a helmet And some scientists thought
It could've made a sound like It might've made a sound like
I could've made a sound like But I probably made a sound like
Corythosaurus in the forest Feeling so proud
Crest like a crown and it made a sound You can bet it's loud
I'm 6 feet high 30 feet wide, 3 to 4 tonnes
Front leg's short, back leg's long But I can still run
When I find food I chop it up with my duck-like beak
In the back of my jaw, it's plants I gnaw With my hundreds of teeth
I'm bent down, low to the ground All fours when I roam
The thing I like best Is the crest on my dome, see?
No other dinos rock this crest that I got
See, it looks like a helmet And some scientists thought
It could've made a sound like It might've made a sound like
I could've made a sound like But I probably made a sound like
Next stop, Refrigadome.
Ah, the Refrigadome.
It sure is a lot hotter than I remember it.
Help!
Get me outta here! Is anyone out there? Help!
Tundra Tara? Hold tight.
Bing! It's so good to see you.
Oh, it's been a long time.
It's good to see you too, Tundra Tara.
Guess it's too hot for hugs right now.
So, what brings you to the Refrigadome anyway?
I need to know how refrigerators work. Maybe you could help?
Oh, I'd love to show you, Bing.
But as you can see,
our refrigeration system is broken right now.
I put in a repair request.
It'd be six weeks before they can send a technician.
I'd fix it myself, but I can't fit through the airlock door.
This door? I can fit through that.
You're right!
If you go in, I can talk you through how to fix it, step-by-step.
Let's get you suited up.
Refrigeration system, prepare to meet your match.
All right, let's go over the plan.
Plan? Who needs a plan?
Wait! If we don't follow the plan, it could be very…
dangerous.
Nothing to worry about. I'm great at stuff like this.
See? Solved your problem. The system is flooding.
That liquid's supposed to be there.
It's refrigerant. It's the key to cooling off the Refrigadome.
Swim through that door, I'll show you how it works.
You should be coming up to a large chamber straight ahead.
Whoa, what is this place?
Now you're inside the compressor.
It pushes refrigerant through the tubes in a big loop.
There's a plastic bottle jamming things up.
A plastic bottle?
Oh, for crying out loud!
What? I thought it was a rubbish chute. Not my fault the door isn't labelled.
Okay, Bing. We need to remove that plastic bottle.
-But be careful. Make sure-- -Got it! Plastic bottle removed.
Bing, you gotta get outta there, fast!
Bing, can you hear me?
Bing!
Hey, StoryBots. Why do moths always go to light?
We're on a routine mission to scan the mysterious region of space
known as the Cocoon Belt.
Ensign Hub, Ensign Bub!
How many times? Stop playing with those lights!
Red alert! Stations, everyone! Checkmark, report.
Something very large is slamming into the ship.
Sensor readings--
Sensor readings indicate that the threat is a giant moth.
Checkmark, take evasive action.
It is still following us!
Captain!
Hull breach on deck 88!
Fusion reactor is close to a meltdown!
Captain, I've fallen, and I can't get up.
Potty, engineering report!
I'm doing the best I can, but the ship can't take much more.
More moths approaching. Thirty seconds to impact!
Ensigns Hub and Bub, scan the…
Lights.
I told you to…
Wait a minute. Spork!
-Yes, Captain? -Aren't moths attracted to light?
Yes. According to records,
many insects, including moths,
use a light source to help them fly in a straight line.
One common theory says that before humans or StoryBots,
the only consistent light sources on Earth were the sun and moon.
By keeping them at a constant angle when flying,
moths and other insects could be sure they were moving in a straight line.
When other lights are introduced,
moths become confused and are attracted to those lights.
That's it! Prepare a glow rocket set to full brightness.
Ten seconds to impact.
Immediately after the glow rocket is launched, turn off all power to the ship.
But with no power, we'll be sitting ducks!
Checkmark, fire the glow rocket on my signal.
Five, four, three, two…
Fire!
-Yeah! -We did it!
But how did you know?
Moths use light as a way to navigate.
I figured they might use the ship as their guide.
Much like how moths and other insects huddle around streetlamps on Earth.
Hub, Bub, please stop!
-What's that light over there? -Let's follow it.
The scientists say That before electric lights
When moths took flight In the dark of night
The moon would guide them with its glow That's how they'd know which way to go
Electric lights are now everywhere
When moths fly through the air And come near a lamp that's brightly lit
They get confused and follow it
-This way! -Over here!
Maybe the streetlight attracts them 'Cause it's brighter
So much brighter
Maybe it looks like another moon That they've found
That's not a moon
But this light gives them no direction They can't make a course correction
So there's no place to go But round and round
Round and round and round
They flit and flutter endlessly Around the nearest light they see
Until the light goes off, and then
The moon's bright glow Can show the way again
-Come on! Let's go! -This way!
Next stop, still the Refrigadome.
Bing? Bing!
Come in, Bing. Are you there?
I'm here.
But I don't know where "here" is.
You're in the refrigeration system, or more specifically,
the coils that run inside and outside of the Refrigadome.
What do coils have to do with making the Refrigadome cold?
Everything!
Refrigerant moving through the coil in the Refrigadome captures heat.
When it moves through to the coil outside, it releases heat.
How does it do that?
Through a cycle of evaporation inside and condensation outside.
Tara, I think I might be kind of stuck.
Fantastic! You've reached the expansion valve.
You're about to re-enter the Refrigadome and experience evaporation first-hand.
I don't think I like evaporation!
Where am I now? Where did all the refrigerant go?
Oh, it's still there, Bing.
It just turned from a liquid into a gas.
That's evaporation.
How does evaporation make the Refrigadome cold?
When the liquid refrigerant turns into a gas,
it captures heat from the air around it.
It's getting kind of warm in here.
And windy!
Hang on, Bing.
You're about to be pushed to the outside coil.
The refrigerant turned back into liquid.
Exactly. When a gas turns into a liquid, that's called condensation.
Condensation releases heat.
So, evaporation on the inside coil captures heat?
Uh-huh.
Condensation on the outside coil releases it?
You've got it.
Wait, so refrigerators don't add cold air inside?
They just take heat away?
Precisely, Bing.
Evaporation and condensation.
Capturing and releasing heat over and over and over and over again.
That's awesome!
Sure is. And now you have everything you need to deliver your answer.
Not exactly, Tara.
What? What else could you need to know?
How do I get out of here?
Re, re, re, re, refrigerator
A refrigerator's got a big job to do Gotta chill those foods and drinks for you
The way it works is cool as can be A fluid called refrigerant is the key
When it's pumped inside That fluid will pass
Through evaporator coils Where it turns to gas
When the liquid evaporates Here's the rule
It absorbs heat around it So the air gets cool
Re, re, re, re, refrigerator
Now, as a gas, the refrigerant goes Into the outside coils
As it flows through those It condenses back into a liquid there
Releasing heat from inside To escape through the air
Evaporation inside Removes heat in the day
Condensation outside lets it flow away
The cycle repeats, getting rid of the heat The food stays cool and good to eat
So cool, so cool
Yeah, that's how to make things cool
Re, re, re, re, refrigerator
Hello, Ms Canteen Dinner Lady? You there? Come in.
Thank goodness you're back.
If I don't get this refrigerated, I'll have to throw it away.
-Did you find out how refrigerators work? -I sure did.
Thanks to repeating cycles of evaporation and condensation.
I work in the culinary arts, not the science department,
so I need a slightly better explanation.
Evaporation is when liquid turns into gas.
That process captures heat in the refrigerator.
Okay.
Condensation, when gas turns into liquid, releases the heat outside.
Okay, Bing, I'm so confused, because I don't see any evaporation
or condensation happening inside or outside this refrigerator.
It takes place in the coils that hold the refrigerant.
Refrigerant?
Hold on a second.
Bing, you're a genius. I can see we're out of refrigerant.
Looks like your problem's solved.
Not only did you just save Taco Tuesday,
which deserves a medal of honour in my book,
you just saved me from a mob of angry kids.
Really?
Oh yeah.
Those kids really like their tacos.
