Inhale
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!!
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.
We use it for ballons and we also use it to make are voices cool(:

helium is used for excitation of neon atoms in helium neon laser..
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

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