Old video showing superfluid helium

I thought this was pretty cool:

You can skip about the first 2 minutes, which are just the credits and some footage of them transferring some fluid.

Nice concrete demonstration of various fun stuff such as superfluidity and second sound.

Great demonstration, wish they had this quality of explanations still (or maybe I haven't found them yet).
