Jay Leno inhales "anti-helium"... Hilarious!
Because the sulfur hexafluoride gas has a high density (over five times denser than air), it can be poured into open containers, like beakers and fishtanks. Moreover, light objects, e.g. ship-like vessels made out of light wood or aluminium foil containing air inside, can float on the gas.
Another effect is the gas' ability to alter vocal sound waves. The gas can be breathed in a small, safe amount and cause the breather's voice to sound very deep. This, too, is due to the gas' density.
