Flying in the Sky
Science brain teasers require understanding of the physical or biological world and the laws that govern it.
One day, a boy noticed a man selling balloons that he was blowing up by himself. Being a young child, he was excited and ran to get one. When he bought it, however, it wouldn't float up in the air. Why is that?
HintThink about the properties of air.

Answer
It wouldn't fly simply because it was mouth blown. When it floats up, it's because of the type of gas inside it, which is helium. Helium is less dense than air, so it floats. Carbon dioxide, on the other hand, is not.

| I'm sorry, but that is not a very good teaser at all.
Better luck next time. |

| Way to easy. Sorry but everyone knows that! This is not a teaser, it does not challenge at all. |

| SO sorry. But I have a list of reason why this cant be a good teaser.
1) Mouth blown baloons DO float a little
2) who would know that unless they are in mmiddle school?
There are more, but you get my point. Good luck next time.  |

| Too easy.As everybody else
said.
Most balloons don't float anyway.
Anyone could have guessed that.
But it isn't too bad.I've read much worse. |

| a few things. first, you have to give the creator some slack! the difficulty rating WAS on the label thingy. second, and this is directed to lastlyboo, i knew mouth blown balloons didnt float when i was in first grade, so do not say that only middle school students could get that. sorry if it seems offensive (which im trying not to be) but its true |
