Re: Mythbusters do a shooter
the original idea of the myth, that a football could be made light enough to hang in the air for several seconds, by filling it with helium, goes against all the laws of physics.
If something the size and shape of a football was light enough to 'hang in the air' then it would not have enough mass to be kicked more than 3 feet.
they talked about this on the program but didnt explain it very well.
