Helium is a gas so it doesn't really have a look, but it has a color. If you go around in a kindergarten asking what helium is used for, the kids will obviously tell you that it is used for pumping balloons. The helium in a balloon tends to keep the balloon floating in the air.A cool thing about helium is that if you breathe in the helium for a while, then you talk, You have a really high pitched voice.
