-Hey, there! -How's it going?
Hi, Beep. How many muscles are there in my body?
Wow! There are over 600 muscles in the human body.
In fact, it takes over 40 of them just to smile.
Like this.
Hi, Bo. Do you want to play hide and seek?
Oh, I love hide and seek!
One, two, three…
We're starting!
Four, five…
Wait! No…
Six, seven…
-No. Over here! -Eight, nine, ten.
Goodness!
Where are you hiding?
Hi there!
I found you.
Oh, yes. You got me!
Well, that was fun. But also stressful.
Boop.
Linguine, pepperoncini, courgette, ham, Spam, clams…
Whoa, Bang, you're on a roll with those answers.
Nah, I wasn't answering questions.
I was just ordering a burrito.
You put all that on a burrito?
Yeah, man. Variety is the spice of life.
Want a bite?
We've got a Level Three coming in.
Hey, StoryBots. It's great to meet all of you.
Holy… bananas!
Are you seeing what I'm seeing?
Boop!
My name's Mr. Wonderful,
and I have a little TV show called Mr. Wonderful's Land of Imagination.
Oh, we know who you are, Mr. Wonderful.
You're, like, totally our idol and stuff.
Yeah. We grew up watching your show!
I've seen all 905 episodes! Twice!
StoryBots, you all are so kind.
I wish I could sit and chat and get to know each of you,
but I have a problem on my hands.
We would do anything to help you, Mr. Wonderful.
Yeah, what can we do for you?
It seems that the magical door knocker to the Land of Imagination
has fallen off.
What?!
If you can't use the magical door knocker--
You can't get into the Land of Imagination!
And millions of kids will be totally disappointed and stuff!
Yeah, we are in a little bit of a bind, StoryBots.
What? The door knocker to the Land of Imagination has fallen off?
The show starts in 17 minutes! What are we gonna do?!
As you can see, everyone around here is a little upset. A little.
You actually don't look that upset, Mr. Wonderful.
Yeah, you know, it's kinda my thing.
Have you tried to glue the door knocker back on?
Actually, Bing, I did, but the glue didn't work.
Boop boop, boop, boop boop!
Exactly, Boop. If you can show me how glue works,
then I can reattach the door knocker
and get back to the Land of Imagination, and we'll have our show.
Hey, my friend Emmett is super into making models,
and he uses glue all the time.
Maybe he can help us with how glue works.
-Of course! -Emmett could totally help!
That's a really good idea, Bang.
I love it. And I sure would appreciate if you could help.
There's only 15 minutes to showtime!
And so would he.
Don't worry, Mr. Wonderful. We are on the job.
Answer time!
Hey, StoryBots. How will I know what direction I'm going in?
Do you feel lost?
Directionless?
Worried that you or a loved one are unable to navigate?
I'm telling you, I know where I'm going.
Well, now there's hope.
Now, there's cardinal directions.
With four primary directions,
north, south, east, and west,
you'll be able to find just about anything.
There are many ways of guiding your direction,
such as a compass, the sun, or even the stars in the sky.
Full speed ahead, crew! Follow the North Star!
Once you've found your orientation,
it's just a matter of knowing that north is opposite south,
that east is 90 degrees clockwise from north,
and that west is opposite east.
Every time I wanted to watch the sunrise, I'd look the wrong way.
And watching the sunset was even worse!
But now I know the sun rises in the east and sets in the west,
I haven't missed a single one. Thanks, cardinal directions!
Side effects of cardinal directions include arriving on time,
a stronger grasp of geography, and understanding maps.
Ask your cartographer if cardinal directions are right for you.
For those in search of more clarity, try intercardinal directions.
Use only as directed.
We know the search can be long,
but with cardinal directions, there is a way.
Maybe we should ask someone for directions.
Hey, StoryBots. Can you please tell me a fun fact?
Fun fact number 101.
Did you know that snails can take super long naps?
Some have even slept for up to three years!
Okay, sleepy head. It's been three years, time to wake up.
What time is it?
November.
Just five more months, please.
Okay, dear.
Such a little angel.
Next stop, Emmett's mum's house.
Emmett? You, like, in here?
Wow. This place is wild.
And a "choo choo" to you too.
-Hey, Bang! -Whoa!
Hey, Emmett. How you doing, man?
Great, Bang. I just glued on the last piece of my biggest model yet!
Whoa. Awesome.
But speaking of glue,
I was hoping you could help me answer a question for my friend--
Emmett, honey, come upstairs for lunch. Bang, you're welcome too, dear.
Thanks, Mrs. Emmett's Mum,
but I totally ate a burrito before I got here.
Be right there, Mum.
Sorry, Bang, but Build Your Own Sandwich Day waits for no man.
Feel free to look around while I'm gone.
Build Your Own Sandwich Day Gotta build that sandwich
Don't worry, Emmett. Your stuff is safe with me, man.
Huh? No way!
A perfect scale replica of the Space Blower-Upper 9000
from SpaceBots in Outer Space?
Man, this is, like, the most totally rare, one-of-a-kind model I've ever seen.
Better be super careful around this one--
Huh?
And one more slice of bread ought to do it.
Hurry and eat, Emmett. You don't want to leave Bang waiting.
Bang's the chillest guy I know. What could possibly go wrong?
Hey, what's up?
Phew. That wasn't so bad.
Hey, Bang, are you--
Hi, StoryBots, my name is Finley.
How deep is the ocean?
-Hey, Dink? Yeah, Doink?
How deep do you think the ocean is?
Wait, 100 feet?
100 feet? It's gotta be way more than that, like--
Like 103 feet!
Wait. You think it's three whole feet more than 100?
At least!
Oh, yeah? Who told you that? A zebra?
A zebra? That's funny. You're a real comedian, aren't you?
Yeah, and I got a joke for you.
I know a guy who thinks the ocean is 103 feet deep!
That's it! I cannot be friends with someone who thinks
the ocean is less than 103 feet deep.
Oh, yeah? I won't be friends with you either then, okay?
-Fine. Okay, fine. -Fine.
-Fine! -Fine!
Pardon me, but I couldn't help overhear your argument
and thought I could settle matters.
The deepest part of the ocean is 36,200 feet,
or almost seven miles.
Yeah, right, buddy, and I'm the King of England!
36,000 feet?
Can you believe that shark thinks he knows how deep the ocean is?
What would a shark know about the ocean?
We're diving down, down, down, down And then we'll dive some more
In the big deep ocean That we love to explore
We're dropping low, low, low, low Because we're going to go
To the deepest known point On the ocean floor
Under the waves, there are valleys And hills all around
On the average It's about 12,000 feet down
That's over 1,000 school buses All in a stack
Or 800 T-Rexes
What a fun fact!
But there's a way, way, way, way Deeper place we know
The Mariana Trench Is where we've got to go
Where the lowest known point Is called Challenger Deep
As low as 36,200 feet
That's 20 tall skyscrapers Under the sea
Or 118 Statues of Liberty
If you could sink Mount Everest Down that deep
There'd be a whole mile of water Up over its peak
We're dropping down, down, down, down And then we'll drop some more
Where hardly anyone has ever gone before
We've got to dive, dive, dive Till finally we arrive
At the lowest known point On the ocean floor
Nearly seven miles down On the ocean floor
Next stop, Emmett's mum's house.
Emmett, dude, I am so sorry.
I am totally gonna fix all these models, starting with this ship.
Oh. Well, at least I saved the Space Blower-Upper 9000?
They're-- They're all broken.
This… is…
amazing!
Uh, come again?
Think of how much fun it'll be putting all these models back together!
Oh, man, that is such a relief.
I thought you were going to totally freak out.
So, while we're fixing stuff,
could you tell me how glue works for Mr. Wonderful?
Well, you've come to the right place.
I know all sorts of ways glue works.
In fact, I can show you two main ways that glue works.
The first is called mechanical locking.
Mechanical locking, huh? How does that work?
Just listen.
When you use a gob of glue Just what exactly does it do
To get things sticking?
It can fix a flower pot Or any broken toy you've got
But how?
If you magnify the smoothest stuff
It's coarse and rough, you'll see
Cracks and dents are many Yes, there are plenty
Here and there, everywhere Roughness is the key
Glue goes into tiny cracks It oozes into all the gaps
And there it hardens
Everywhere that it can drip It gets a firm and hearty grip
And so
When it dries completely Then its grip is good and strong
There you go, good as new Through and through
'Cause the glue won't let go
That's mechanical locking.
But glue also works on a molecular level.
Atoms make up everything That's the rule
Though they're tiny, not very large
And they combine into clusters Called molecules
Which often can have an electric charge
Those have a couple of different ends
Positive and negative too
And when opposing ends line up They stick to each other
Like pairs of magnets do It's true!
There's a name for that. Van der Waals forces.
Now the molecules of glue Are clinging by the millions
To the things you're joining
-So it helps them stick together -That's the coolest thing I've ever seen
Glue can work in many ways
I've shown you only two
Glue!
But when you build a model truck Or fix a handle on a cup
Just think of all the great things
Glue can do
Whoa!
Man, Emmett, you sure know your glue.
Well, better give Mr. Wonderful his answer. Thanks, man!
No problem, Bang. Any time.
Take care, brother. See ya. Bye!
See you later! Take care! Goodbye!
Oh, dear, it's broken. Guess I gotta fix it again.
Welcome, class. There are two primary theories
that explain how glue sticks things together,
which my assistant, Gopher, will help me demonstrate.
The first theory is called mechanical locking.
Even the smoothest-looking surfaces are rough
when you put them under a microscope.
Mechanical locking happens when wet glue pours into all of the small crevices
and dries.
It grips the microscopic rough surfaces and holds them together.
The second theory is called van der Waals forces.
It claims that things stick together at the molecular level.
Molecules are groups of atoms.
Some of them have positive charges, and some of them have negative charges.
When molecules with positive charges
and molecules with negative charges line up, they stick together.
Similar to the way opposite ends of a magnet stick together.
While van der Waals forces and mechanical locking
are the primary ways that glue makes things stick together,
people are still learning about how glue works,
and inventing new ways to make better glues.
Isn't that right, Gopher?
A monster!
Class dismissed!
Run for your life!
Hello? Mr. Wonderful? Are you there?
Bang, I'm so glad you're back.
Did you figure out how glue works so I can get the knocker on the door?
My friends are getting a little antsy.
It's only one minute till showtime! We're doomed!
I sure did, Mr. Wonderful.
But first, can you tell me what the surface of your door feels like?
Why, Bang, it's incredibly smooth.
Like my bald head.
Therein lies the problem, dude. It's too smooth.
Do you happen to have any sandpaper nearby?
You know what? I do have some sandpaper.
Right here.
Sweet! Now all you've got to do is sand down the part of the door
that the knocker sticks to.
Bang, why are we using sandpaper to make the smooth door rough?
It creates grooves and crevices that the glue can sink into.
Then when it dries, it'll, like, totally hold the knocker in place.
That's called mechanical locking.
Wow. Sounds very complicated.
That's nothing, man. You should hear about van der Waals forces.
Done!
All right. Now try re-gluing that knocker back on.
Look at that. With the rougher surface, the glue stuck the knocker to the door.
Mechanical locking for the win.
Bang, thank you so much for all your help. I wish I could stay and chat, but--
There's only ten seconds to showtime!
But it looks like my show's about to start.
It's our pleasure, Mr. Wonderful, dude.
-Glad we could help! -Good luck!
Thank you all, StoryBots.
I love you, and I'll see you in the Land of Imagination.
