Helium is a tasteless, odorless, nonflammable, non-toxic, inert gas.
Most of the world’s helium comes from the Texas panhandle, Oklahoma, Kansas and the Rocky Mountains’ eastern flank, other sources include the Middle East and Russia.
Helium is the light gas with heavy uses. It creates the controlled environment necessary for manufacturing semiconducting devices and fiber optics and the extreme temperature needed to cool MRI magnets. Helium also brings lift to balloons and acts as a carrier gas for oxygen in synthetic breathing mixtures.
