99% of amateur projects can be achieved without sulphur hexafluoride, unless you're doing something very well engineered and very professional (like Bert Hickman's SF6-quenched HV relay), I'd worry about you using it. =P

Tin foil boat demo More detailed tin foil boat demo (I couldn't try this but I thought remote control ships could be cool also, I couldn't try this aether but I wondered if you used a swimming pool whether you could float something that could carry a person) Tin foil platforms\balls\Ufo's Being a "Demon" on haloeen by using it on my voice, is verry effective, makes you sound like Darth Vader.
I'm not spending £500 on one bottle of it though.

I tried to get some after I saw that youtube video, too. I got some very rude replies for gas companies stating "no one sells bottles that small". Small to them is 50kg!

SWIMMING in / BREATHING sulphur hexafluoride? This is why people will want to know what you're trying to do, before helping you source SF6.
[edit:, I'm guessing from your recent post that you were not serious. I'm more worried about the potential litigious nightmare for 4HV if you were to breathe SF6. 'Swimming' is my comic metaphor for 'boating'.]

I looked in the catalogue at work. You can buy a half pound tank of it from Aldrich (they may be fussy about selling to individuals rather than companies) it was about £160 (last year's catalogue price)- roughly $300. I guess that stops you worrying about whether or not they will sell it to you.
SF6 is, btw, practically inert and non toxic unless heated strongly when it gives rise to decomposition products that are an absolute pig.

Matt Bingham wrote ... something about a post he had not properly read
Please read my post more thoroughly before you cause me to sound so uninformed. Often I am uninformed but here I do know roughly what I am talking about.
I never said I wanted to (or would be able to for that matter, im too heavy) swim in it. It's safe to take one breath at a time, it absorbers the high frequency in your voice. It's only a problem if you continuously breath it or take breaths frequently, also I never said it would be practical to get a swimming pool full, I was referring to that if it could be done then perhaps a large enough craft (like the foil craft) could be constructed to carry a person safely above the level it was at.
