Your post made me curious about the other uses for helium and I found this to be hilarious, given the timing.
Cryogenics, superconductivity, laser pointers, supersonic wind tunnels, cardiopulmonary resuscitation pumps, monitoring blimps used by the Border Patrol, and liquid fuel rockets all require helium in either their manufacture or use.
Helium is also mixed with oxygen to supply breathing gas to saturation divers.
