Helium is commercially recovered from natural gas deposits, mostly from Texas, Oklahoma and Kansas. Helium gas is used to inflate blimps, scientific balloons and party balloons. It is used as an inert shield for arc welding, to pressurize the fuel tanks of liquid fueled rockets and in supersonic windtunnels.
It is lighter than air so it is used in balloons and airships (as a gas) to make them float and as a coolant (as a liquid). And also when you suck helium your voice changes and goes really high pitched and squeaky (your voice changes back to normal almost staight away).
