Everyone knows that inhaling helium will cause your voice to become very high. Inhaling sulfur hexafluoride on the other hand, will turn you into a demon. No, I’m serious. You literally turn into a demon.

oh and Wheel nut if u say that your alergic to gas then u would die because oxygen is a gas

man i love mythbusters.even though im only 10 years
old even i know that if u inhale something denser then air that the sound waves your vocal cords produce will take longer to travel out making it sound louder and the opisite happens wen u enhale

Screw the warning, I WANNA TRY THAT!
And I second the motion about "gas replaces breathable air". I believe it is true that your body gets no oxygen as long as the foreign gas is in your lungs. But I think there's also something to be said about being allergic to the gas...

Your voice would start out high then as the helium is exhaled, youd get a low voice from the hexaflouride in the bottom of your lungs

this just popped up in my mind while listening to adams demon voice for the 2000000th time; what happens if you get a balloon and fill it with some helium and just as much hexafluoride, not too mutch, just enough to completely inhale all the air that was in the balloon. now what happens when you talk? i think the 2 gasses quickly seperate, helium up and hexa down, so when you talk you have a really high voice and then a really low voice...

yes but mixing folks, mixing...eventually it will dilute out, i swear it will. here's what you do, go get yourself a 5 gallon bucket, put a gallon of water into it and then 3 gallons of vegetable oil in it, stir it around for a while, stir like crazy to simulate the turbulent way air enters your lungs, then pour 2 gallons out, then fill it up with 2 more gallons of oil, this 5 times and then let it sit, then let me know how much of that gallon of water is left at the bottom ok? boo. yah.

and just because you exhale deeply doesn't mean that you will get it out because your lungs wont close enough to push it all out since the walls of your lungs can never touch or they will stick and you will die so you always have room for it to sit.

the other issue is that the gas is heavy, so it has a tendency to sit in your lungs unless sufficient force is used to get it out

hanging upside down would make it as easy to clear as helium, which floats out of your mouth

twixman, you're wrong, but not entirely. density aside, breathing deeply in and exhaling as much as you can would probably clear it out in 2 or 3 breaths, same as helium. the real reason this is a "do not try" thing is because, well, some people are allergic to helium, and it's damned hard to find that out unless you try it, and if you try it you'll probably just die. so i assume the hex is similar, you could just die, immediatley. hooray allergies!

correct me if i'm wrong, but wether its 6x more or less dense, evry time you deeply ex- and inhale, the gas that is still left in your lungs will equal the density with the "normal" air. this should mean that after a few breaths it should all be gone.

What Lobo said.
Because sulfur hexaflouride so much denser than air, it has a tendency to sit in the bottom of your lungs, reducing their functional capacity and effectively asphyxiating you.

I have heard that hanging upside-down for awhile can help you breathe it out, but I don't know how true that is. Of course, hanging upside-down for too long can cause other problems...

You know, when he tells you not to try something at home, it shouldn't be so tempting to do so.

just remember that since its so dense, you have to work to get it out of your lungs, and as long as its in there you don't get any oxygen...

OH *gets idea*
sorry about screwing over your warning but this give me the idea of going to a child's birthday dressed as a clown and inhaleing sulfur hexaflouride and really messing them up! hahahahaha*breaths in* ahh the child hood momeories...
