The song '99 Luftballoons' / '99 Red Balloons' was released 38 years ago, and sold 2,866,500 certified copies. If everyone who bought a copy listened to it twice a week since it came out, and released 99 balloons every time they did, they would have released 1.1 trillion ballons.

Sorry to burst your balloon, but there isn't enough rubber.

How much rubber is there?

It's hard to quantify, because the market is so elastic.

Even saying that is a stretch

That's 1.4 x 10^12. So, it's a cube of balloons a bit over 10,000 balloons on a side. If the balloons are 1' cubes, then the whole assembly is about two miles on a side.

Quite a party.

Are they big or small party balloons?

Assuming medium size, then, @giarc:

> I would say that no one on Earth could comprehend 1.4 trillion balloons

Consider this: If everyone on the planet got 1 party balloon every month, we'd deplete that helium source in about 10 years.
