We use it for ballons and we also use it to make are voices cool(:
You can use air but it won't float so I would recommend helium. If you suck in helium, it will make your voice sound weird.... Try it!!
Inhale
Liquid helium is used to cool the superconducting electromagnets.
helium is used to cool superconducting magnets in mri scanners as helium is lighter then air airships use them as gasses
What is doubtless the most common use of helium by the elderly is the getting and giving of helium balloons. "Older" people don't do a lot of mixed gas diving, inert gas welding or other activities like that.

helium is used for excitation of neon atoms in helium neon laser..
Inhale
the use for balloons mostly
Liquid helium is used to cool the superconducting electromagnets.
Helium
its the 2nd element on the periodic table and it makes things lighter, such as helium balloons, which float as helium is lighter than air

Helium is less dense than air, and therefore the balloon will float.
Humidified helium replaced oxygen to prevent further erosion
Helium is used to reaplce hydrogen on a n airplane because it is nonflammable
