Most of us think of the helium as that funny air we use to fill up balloons to make them fly. The government uses helium to maintain the proper pressure in rockets. Helium is used in heliarc welding and in scientific balloons. Underwater divers sometimes use a combination of helium and oxygen to avoid nitrogen narcosis, which is a painful illness that occurs at significant underwater depths. For Balloons Helium is available in disposable tanks, used for filling party balloons. Tanks for this type of helium use can also be rented. These tanks are often equipped with a balloon-filler nozzle or valve. To fill a balloon, the opening of a balloon is placed over the nozzle.
