Sulphur Hexafluoride

I just gotta get myself some of this stuff. Wonder what would happen if you stick some water in it and a mini fogger?

Apparently, (well wikipedia say so),

Because the gas has a high density (six times more dense than air), it can be poured into open containers, like beakers and fishtanks. Moreover, light objects (e.g. made out of light wood or aluminium foil) can float on the gas.

Nice
