Herro. Origami is the ancient Japanese art of paper folding.
With a single sheet of paper,
you can fold and make such beautiful things as this crane.
Or this frog.
Or you can make this paper plane, this groovy hat or a telescope.
See?
Wow, that's very impressive.
- May I look? - Sure.
- Idiot! - Oh!
Have you ever heard you can't fold a piece of paper
more than seven times?
- Six. - It looks like it's true.
- Seven! - Yeah, not gonna get eight.
I reckon we'll get eight.
- (Grunts) Maybe not. - Nah.
But, then, have you ever wondered,
what if I had a really, really big piece of paper?
BOTH: Guess what we've got! A really big piece of paper!
Let's go to our corners.
One...
BOTH: Two.
Three.
Four.
Five.
Six.
BOTH: Seven!
Eight!
RUBEN: So, hang on a minute.
Looks like that old fact is a load of baloney.
Well, almost.
For small bits of paper, the seven-fold rule is usually true.
BERNIE: Now, there are two reasons
paper gets harder and harder to fold in half.
Every time you fold, it gets half as big,
and smaller things are harder to fold.
On top of that, every time you fold it, it gets twice as fat,
and thick things are harder to fold.
RUBEN: After 6 folds, the paper is 64 sheets thick.
After 7 folds, it's a whopping 128 sheets thick.
BERNIE: Doubling doesn't sound like much,
but when you do it a lot, it gets really huge really quickly.
There's a word for when things just keep doubling like that.
It's called 'exponential growth'.
- Say it with me, Ruby. BOTH: Exponential growth.
- It isn't just paper that does it. - Nup.
RUBEN: Bacteria double in number all the time,
and they look something like this row of rice,
doubling their numbers every 20 minutes.
So in a few hours,
one little bacterium can turn into thousands of the suckers.
So, kids, never leave your sandwiches lying around for hours.
- Especially not rice sandwiches. BOTH: Eugh!
And bacteria aren't the only thing that grow by doubling.
So do nuclear explosions! (Screams)
RUBEN: A nuclear reaction starts with one little atom
smashing into another and breaking it in two.
Then those two bits smash into two other atoms,
and break them into two!
BERNIE: And it just keeps on going
until you end up with a giant huah of a bang.
Look, we'll show you. Captain Ruby, 'ow iz zat bomb coming along?
Um... Does zee black go to zee red or zee black go to zee black?
Um... Never mind, Captain Ruby.
We'll show you one we prepared earlier on a small Pacific island.
(Boom!)
Sacrebleu! Zat was a big one. He-he-he-he-he!
- Eh, OK. Zee black goes to zee red. - Ah! Captain Ruby, not yet!
(Screams) Sacrebleu!
