SF6 you can buy from pretty much any gas company. It is really expensive, like $1000 a bottle for those standard tallish ones.

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!

Go to a specialized gas company and ask for a lecture bottle size. I think the smallest amout you can purchase is 1 pound.

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.

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.

Wouldn't xenon be cheaper/easier to get and also lower your voice? Just by analogy with helium, it's denser than air and so the different speed of sound should make your voice sound funny. Again, I'd be veery careful with too much since your lungs would have much more trouble displacing it than helium.
Or does SF6 work though some other effect?

Xenon is awfully expensive. Quite a bit more than SF6 I think.

I would think Xenon would cost a huge amount more. Xenon is a noble gas, so the only way to get it is by extracting it from air, which is an insanely small percent Xenon (90 parts per billion or 0.000009%)!
Sulfur and Fluorine, however, are present in natural compounds (fairly common compounds). Through a series of processes, they can be extracted and reacted to form SF6.
I wish SF6 wasn't so expensive...that foil boat demo is so cool!

Argon is fairly common for welding purposes, probably not too pure for industrial purposes, and I dont think its 'cheap' either but most likely better then xenon :p

Not only is xenon expensive, it also acts as an anaesthetic.
