A physics demonstration personality wants to use sulpher hexafloride to
demonstrate the opposite of the helium squeeky voice effect. He breaths
in a lungfull of SF6 and his voice sounds gruff as he speaks.
His question is where can he get SF6, hopefully reasonably cheaply, or a
reasonable substitute high density gas that won't harm him.
