The first picture shown after "liquid Helium"

This very interesting picture is taken from an excellent video demonstration presented here. I have no idea what I'm doing here, but I know I spent hours looking for this video through the wikis for superfluidity, second sound, etc. which all contain stills from this video but no attribution. I'm not sure how to add it in, but I think this video - especially the original if it can be found (this uploader added a splash and some short overlays) is an excellent reference and his clearly delivered information coupled with excellent videography helped me understand concepts I have struggled with for a while. — Preceding unsigned comment added by 203.27.186.78 (talk) 05:29, 9 February 2021 (UTC)[reply]

The original film is copyright-expired, so if we can find it it can live on commons and stills can be used freely. DMacks (talk) 06:45, 9 February 2021 (UTC)[reply]

Add "at STP" to the Boiling-point

Just like is done for the Melting-point. If feels a bit inconsistent now. — Preceding unsigned comment added by Koitus~nlwiki (talk • contribs) 20:52, 15 June 2021 (UTC)[reply]

Other history

Helium was once also produced by fractional distillation of air, and may still be in some parts of the world. In the UK in the post-war period, for example, there were two common varieties of industrial Helium, the expensive US Helium was the purer, while the locally produced variety was from air liquification.

condense hydrogen and oxygen to make rocket fuel

Definitely oxygen can be liquified without liquid helium, usually fractional distillation of liquid air. Hydrogen can be liquified without helium also, but maybe it is easier with helium. Gah4 (talk) 01:19, 11 February 2022 (UTC)[reply]
