Would this floating idea be plausable?
Are there any gases that are more dense than the human body?
If so, we could float on this particular gas (with gas masks or oxygen tanks of course). This also led me to think about:
Are there any liquids which are lighter than air? We could have a swimming pool of sorts that floats on the ceiling.
All we would need is the right chemical. Any scientists out there?
(I know it is unlikely as states of matter generally mean that in terms of density, Solid>liquid>gas.
