In this video from MythBusters, you can see what happens if you inhale a gas lighter than air (in this case Helium) or if, on the other hand, you inhale a gas denser than air (in this case Sulfur Hexafluoride). In the first case, your voice turns into a chipmunk’s and in the other one into Satan’s!
Very funny and interesting 
Thanks Fepe!
