Superfluid helium

submitted by CaptWillard

1 decade 7 years 1 month ago

This is a short part of a documentary about the amazing properties of superfluid helium, which is a supercooled liquid form of helium. For starters, it can apparently defy gravity. Freaky.

um...any chance of finding the full version?

I don't know, fade. I looked for longer videos with this clip in it, but couldn't find any.

A frictionless fountain?!?! Why don't we have one in our local science museum?

My favorite professor back in the day used to say the sound of discovery is rarely, "Eureka!", and more often "Huh, that's odd". Hurray for the accident of discovery! I find an interesting proposition in that heat actually creates friction. Without heat, you experience such things as these super flows. Would it not be an interesting idea that elements of this universe bring into existence other elements? Like a cascade of meta-rules that we can never be aware of; the rules unfold as other rule sets are propagated.
