I had no idea helium could even be a liquid or was needed for MRI! 😲
So many things screwed up by one madman and his genocidal buddy.

helium turns liquid at extremely cold temperatures (around 4K at room pressure, which is around -450°F/-270°C)
it is specifically used to cool strong magnets, as these magnets need to be superconducting amd we don’t know how to do that at higher temperatures (yet).

MRIs need relatively strong magnets so they use helium for cooling similar to how CERN cools the LHC so that the magnets are strong enough to keep charged particles in at such high energies

And helium’s a limited resource and once it’s gone, we won’t have any left. We can’t make it, so the fact we use it for party balloons is completely bonkers to me.

😱 omg really?? Yes, using it for balloons is ridiculous in thaf case wtf are we doing lol!?!

Aw come on. It’s totally renewable. We just need to wait a couple of million years for the conversion and for it to „bubble up“. What I didn’t appreciate was that it is so light, that it can leave Earth and the atmosphere, and end up in space.
