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 ...
Balloon helium is 3% helium. So every 33 balloons is one Balloon worth of pure helium. No helium starts off pure. It all gets concentrated/separated to get that way. "Balloon grade" helium can be concentrated just fine and considering that thousands of those balloons are filled every day, it is a lot of wasted helium.
*I had my percentage swapped, it seems. Balloon helium is 97% helium.
Last time I bought what I thought was a pure balloon of He, I’m pretty sure it had gotten cut with fentanyl.
How high did it get? Asking for errr... science...
