would a baloon or a barrel 'filled' with vacuum act as a hellium balloon and float in air?
of curse that would require hard shell balloon...
density of air at sea level is 1.22521 kg/m3.
so if we could make a vacuum chamber one m3 big that would weigh 1.22 kg it would float right?
p.s.if the container would be a sphere than it should weigh 252 grams/m2
