An exciting playground on top of a hill.
Phew! It's so hard to go up.
Maybe there's a way to go up at once.
I can't ride a bike. It has to fly like a rocket!
Right! I need a rocket bike.
So how do I make it?
Maybe Mrs. Curiosity knows how.
Mrs. Curiosity is a scientist.
She studies pieces that are smaller than a booger,
and divided into thousands.
She has lots of skills -
fixing a broken machine is easy for her.
She even opens up other things
because she is so curious.
But why?
Why is the
screen black?
Why?
Why are 2,870 cans stacked
into a shape of
pyramid?
She solves difficult calculations and
counts the number of cans
easily.
Why?
Why is the tree tilted?
Oh, a mole has dug up
the ground!
Mrs. Curiosity is curious
about little things that most people don't care about.
She examines them, thinks about them,
and finds out why.
Yeah. Let's ask Mrs. Curiosity!
Why are you
trying to make
a rocket bike?
Because it's hard to
go up to the playground.
But rockets and bikes are
expensive.
I can look for treasures.
There are lots of treasures underground.
Yes.
There are jewels and
gold.
It'll be
awesome!
The scientists that study the movement of nature and outer space
are called physicists.
Mrs. Curiosity and I looked through the whole town.
We'll be rich if we find jewels and gold.
We examined the soil and rocks wherever we went.
Sometimes, we found strange objects.
What's this?
Is it a dinosaur bone?
Maybe dinosaurs
used to live in our town.
Scientists that study what's underground
and what soil and rocks are made of
are called geologists.
We took everything that seemed strange.
We examined the bugs in the soil
with microscopes.
But why?
Why can't I see any gold mine
bugs?
What's a gold mine
bug?
It's a bug that lives in
places where gold is found.
Scientists who study living things are
called biologists.
Then, we roasted the soil and rocks
on a large saucepan, one by one.
But why?
Why can't I see
anything?
What did you expect to
see?
When soil or rocks mixed with gold are roasted,
the gold melts and comes out.
It's because gold melts even at low temperature.
If roasting doesn't work,
let's try
boiling it.
Scientists who study what substances are made of,
what characteristics they have and how they change,
are called chemists.
But still, there was no gold.
I don't think we would find any treasure.
I was walking down the street feeling disappointed and
found an old bike that's been thrown away!
It was broken in many parts.
But it was no problem.
Mrs. Curiosity could fix this easily.
Mrs. Curiosity and I cleaned the bike
and fixed it.
Mrs. Curiosity and I
made a new bike
again and
again.
Now, we just needed to attach a rocket.
A balloon rocket!
A balloon rocket?
How?
I'm not sure. Try to think about it.
I have to go to work now.
How do I make a rocket
with a balloon?
After thinking again
and again,
I finally came up with a
balloon rocket!
Balloon, tongs, paper, scissors, tape
Blow the balloon to a large size and
block its opening with the tongs.
Make a cone shape with
the paper and
attach it on one side of the
balloon with the tape.
When you release the tongs,
the balloon rocket will be launched!
Whoosh!
Finally, the balloon rocket bike was ready!
I attached a long string on the tongs blocking the
the balloon's mouth and tied it on a tree.
When I ride the bike,
the tongs will be released
and the balloon rocket will be launched.
Then, the bike will fly into the air!
"Let's go to the playground!"
I pedaled hard and the balloon rocket
blasted wind.
Whoosh!
But… Oh, dear.
The balloon shrunk in a few seconds
and I fell on the ground.
Why?
Why did this happen?
Right. It's because the balloon rocket was too weak.
I failed this time,
but I’ll make the rocket bike one day!
I'll become a scientist and make a real rocket bike
that flies into the galaxy.
