But I was thinking that the reason a balloon filled with helium floats is that the atmosphere above it weighs more than the balloon and therefore the atmosphere displaces the balloon up.....
If you could produce something that was light and strong (why not use buckytubes to be topical?) and then pumped the air out of it (doesnt have to be all of it.....just decrease the pressure) would the weight of the object decrease? If you kept going would it eventually float?
