Remember the aluminum foil boat floating on sulphur hexafluoride gas we had before? Turns out, if you inhale the gas, it gives you the opposite effect of inhaling helium.

And I thought you have to make a handstand after you inhaled Sodium Hexalfluoride to get it all out of your lung.

nitrous oxide (laughing gas) does the same thin just not as dramatically. have you ever done a whip-it?

I wonder what would happen if you breathed helium AND sodium hexafluoride at the same time…?
(Aside from getting a major case of the dizzies, that is…)

@Denita.
I was thinking the same thing. I think it would be more of a squeaky low pitched voice, because the heavier gas would stay longer (hexafluoride) while the lighter gas (helium) rose. I’m no scientist though.

just one thing… it’s sulphur hexaflouride (SF_6) *not* sodium (Na) …

Oopsie, I also called it “sodium” instead of “sulphur”. My bad!
Eeh, we were only off by a mere five atomic numbers…
