Also, Is it bad for you?

Because the density of helium changes the form of the soundwaves your vocal chords produce.
It is fun, but obviously it's bad whenever you breathe something other than oxygen!
Bye bye brain cells!

Pay no attention to the first answer. Yes, it is all about the fact that helium is much less dense than our atmosphere.
First understand that your voice is produced by vibrating air pushed out from your lungs. When you inhale helium instead of air, the density is changed and thus the sound of your voice is changed.
Its bad for you in the sense that you are not getting any oxygen when inhaling helium. This is never good, however the harm produced by taking in one lungful of helium is very small. Howerver, if you kept doing it, you could pass out. If you were placed in a room with nothing but helium you would die.

It temporarily causes your vocal chords to conract, ths making your voice higher pitched. It's relatively harmless, but use common sense.
