This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

To add on the point of helium being expensive and valuable, it's also extremely important for supercooling MRI's and supercomputers.

I'd rather have more MRI's than zeppelins.

So MRI helium is scarce because the required purity is very high to get the 4 Kelvin superfluid behavior. Helium for filling balloons (of the party type) is a lot, lot cheaper. I don't know exactly how that translates into airship envelope helium, but you can't take balloon-grade helium and put it in your MRI machine.
