Anti-Helium

Brett shares a funny thought about a mishap at CERN.

I have done the breathing-the-helium thing and when I learned that the voice change that happens is simply due to the density of the gas, I have to admit to being skeptical. It just seemed to be an extreme result for a gas that is just a few times lighter than air. But this weekend I saw a demo of the opposite effect with Sulphur Hexafluoride. Wicked. Especially the part at the end.
