Ok heres the deal:

A buddy sets a 5 dollar bill on the floor. He bets you the bill that u cannot jump over it without moving it. The air from your body can move it, but u cannot physically touch it.

This is impossible to achieve, but why?

Thats the problem, i can jump over the bill fine but theres a logically reason why this is impossible. The bill isn't moved, not a trick its exactly as it appears. Theres nothing around the bill to prevent you.

There IS an answer, i don't know it, any ideas?
