I saw Dick Berg suck down some SF6 and sing "Oh So La Me-Oh" in the '94
demo workshop at Notre Dame. He did a head stand to drain it out of his
chest.

What grade was that, Dick?

Do a little more of that work which you have confessed to be good,
Which you feel that society and your most Just Judge rightly demand of you.
Cultivate the tree which you have found to bear fruit in your soil.
If you have any experiments you would like to try, try them.
Now's your chance.

Hi Jason
back in 1994 I inhaled 4 canisters of Sulfur Hexaflouride from "Scott
Specialty gasses" without apparent harm. (Some may argue brain damage,
but I ascribe that to other causes ;-) They have a branch near you, 617
245 8707.
They list no information on the bottles as to the % purity, I'd suggest
you contact them for more info. I remember them being helpful when I
contacted them with the same concerns, I can't find the actual info they
sent me, but I remember that it made me feel OK trying it. Sprott at
Madison Wisconsin (Wonders of Physics - excellent videos) has done it
several times, maybe he has more info. Hope this helps,
cheers,
David

You got it, makes you sound like Darth Vador.

Yes indeed, after 30 seconds bend over to get your head down below
your lungs and inhale/ exhale very deeply, several times, check your
lungs are clear by speaking, if your voice is back to normal, you've
cleared your lungs. Don't hyperventilate, but do make sure it's all gone,
cheers,
David

I've never done it but the Chem Professor I had in college did. I
believe he bubbled the gas through Hydro Fluoric acid? HE said this
would filter out any SF4 or convert any SF4 to SF6. I don't remember
which one. He did it every year with no problems I guess the SF4 is
highly reactive and would eat your lungs out very quickly.

What purity do I need if someone wants to try inhaling SF6? "Instrument
Grade" is available from Airgas, and 99.9% pure. That's a real
measurement. They say they can't sell that grade for human consumption,
but their concerns seems to be about drug-testing forms rather than
toxicity. While I'm waiting for the rep to call back, I'd love some of
that good old fashioned tap-l discussion.
