Sulfur Hexafluoride

What the heck is that???????????

It is a gas that is 6 times heavier than air. Helium is a gas that is 6 times lighter than air, and we all know what happens when you breathe in helium. See what happens when you breathe in sulfur hexafluoride....(don't try this at home!) Turn off the music that's playing (down there on your right) before you watch the video.
