Re: Sulphur hexafloride




First of all, is this stuff safe enough to be taking a lungful? I also
read on an He tank that it is not recommended to breathe in. In this
latter case, is it because of the lower temperature due to expansion? I
can't see it having any other affect.

I have an unrelated question. Does anyone know if the concept of mass, as
the quantity of matter, preceded the notion of inertia? I know that weight
has been used since the dawn o' man but what about mass?

Thanks for the light!

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.
