The helium used for balloons is of low purity.
The shortages you hear about are of pure or near pure helium. The stuff going into the balloons at Tommy's birthday party isn't the same thing used to cool superconductors.
EDIT: And I used to think Reddit was full of ignorant jackasses ...
Using it for balloons is still a waste because that impure helium could be purified for better uses.
No, no it could not.
The stuff used in balloons isn't pure enough to be used for cryogenic purposes, which is what people really want it for.
And before you ask purifying it is really difficult.
yes you can, crude helium + air mixture (few %) is used in first stages of cryogenic helium purifying
Jesus Christ not this guy again....
