See what happens when you breathe it in.

Yeahhh its full of water..... Yeah let me feel dumb....

SATAN!! It'S SATAN HIMSELF ! ZOMGWTFBBQ!!
THAT GAS IS GAS TAKEN FROM HELL!!! BREATHE IT IN AND THE DEVIL HIMSELF TAKES CONTROL OF YOUR BODY!!! BURN HIM AT THE STAKE
ARRRGGGG

now suck in some helium right after that...would it even out?

Or maybe, Spriggan666, just maybe it would create a black hole inside your lungs.

haha
AND THEN SATAN SUCKS YOUR INNARDS INSIDE OUT

Is that safe? O_o

^ was thinking the same thing..Makes sense..Helium=Lighter-than-air, makes your voice all high..

Hexafluoride=Heavier, makes your voice deeper.

Sooo... where can I score me some of this aforementioned hexaflouride?

hahaha drating insanly cool. that guy did sound a little demonic. imagine scaring the poo outa someone with that crap...haha

Is that even save O.o
Freaky

Where the hell can I get some?

Helium I know cannot react with anything, they try to but it's impossible currently. Helium is totally and I mean TOTALLY safe to inhale as long as you have oxygen.

put on a weird costume, and go scare someone with that stuff :P
I think my dad may be able to get some of that

Huh, I gave it a second though...Since helium is lighter than air, it must be easier to get out of your lungs, where as this stuff stuck with him for a while, I guess 'cause with every breath he took in, that air kinda settled on top of the Hexaflouride. So..if you inhale enough, you may put yourself at risk for suffocation? Huh...I'd like to see this stuff react to water? Like would it sink or float. The guy DID say it felt like there was water in the balloon. Just a thought.

i liked the part at the end, that was pretty cool. and dragon if it wieghed as much as water that ballon would have been sagging a bit more.

lmao

@DragonSageX, according to wikipedia it is a highly inert gas. It will not react with anything, it ways about 6 grams per liter, so that guy was a little bit off when he said it looked like the balloon was filled with water.

Wikipedia: "According to the Intergovernmental Panel on Climate Change, SF6 is the most potent greenhouse gas that it has evaluated, with a global warming potential of 22,200 times that of CO2 over a 100 year period"

Not to be fooled around with.....

um . . . y is he using a jonny an not a ballon?
just a thought

WIKI: Because SF6 is relatively slowly absorbed by the bloodstream, it is used to provide a long-term tamponade (plug) of a retinal hole in retinal detachment repair operations.

In a further medical application, SF6 is employed as a contrast agent for ultrasound imaging. Sulfur hexafluoride microbubbles are administered in solution through injection into a peripheral vein. These microbubbles enhance their visibility of blood vessels, to ultrasound. This application has been utilised to examine the vascularity of tumours amongst other things.

Can't be that damaging...

Can you set that stuff on fire?

lol. Get right to whats important, arnt yeh cat.

i would suck that in and say

"U dare stand in my way?!"

I LOVE SCIENCEEEEEEEEEEEEEEEEEEEEE

Hahahaha...Satan sucks your innards out. That's pretty cool though. It would neat to have that if you worked in a drive-thru. CAN I TAKE YOUR ORRRDER?
