Stuff from the past: Liquid Helium

This is a nice video (1963) showing the interesting and sometimes funny effects of liquid Helium II. They also show the large Dewar vessels for containing the liquids. These are impressive, knowing they did not yet have Borosilicate glass but they used 'soft' Sodium glass which is extremely difficult to handle.

*edit
I might be wrong here and it could be Pyrex glass. Pyrex is pretty old.

In any case: impressive.
