Flap, you fool!

Flap your wings Now

So that's the flap, and all the rest of the paper's left over.

Can you flap your wings?

What paper went into that flap?

How would you make a single flap?

I didn't have to try to flap my wings.

We're going to learn how to make one flap.

Well, there are other ways of making a flap.

If I make the flap as skinny as possible,

Quick to assemble. It's got a flap that's the invention.

It's very complicated, but it turns out they flap their wings very quickly.

And if I make the flap from the middle, it uses a full circle.

If I put the flap on the edge, it uses a half circle of paper.

I'm curious, you started your beautiful sequence on flight with a plane kind of trying to flap its wings and failing horribly, and there haven't been that many planes built since that flap wings.

And you can see there, it needs a quarter circle of paper to make a flap.

So, no matter how I make a flap, it needs some part of a circular region of paper.

And he held up the flap of the bar. Mr. Marvel rushed behind the bar as the summons outside was repeated.

Over, and over, and over, again.

Say over. Over.

A butterfly can flap its wings in Peking and in Central Park you get rain instead of sunshine. Was I going too fast? I missed it.

This repeats over and over and over.

Over there, over there!

Over and over again.

They'll play it over, and over, and over.

You do it over and over and over.

It's not over! It's not over! It's not over!

And they've tried over and over and over again.

Its over, its finally over.

Over and over I hear,

It's over, Johnny. It's over!

When it's over, it's over.

And we're seeing it over and over and over again.

One over here, 2 over here, and 4 over here.

I'd seen it happen over and over and over again.

And I see it over and over and over again.

Pull over to the curb over there. Right over there.

And we tackle this problem by building giant, dynamically scaled model robot insects that would flap in giant pools of mineral oil where we could study the aerodynamic forces.

And from that stick figure, I somehow have to get to a folded shape that has a part for every bit of the subject, a flap for every leg.

Fold it in half, fold it in half, fold it again, until it gets long and narrow, and then we'll say at the end of that, that's a flap.

Over.

Over.

Over.
