More material states. Who knew?

A few weeks back I was wandering around online and I found reference to something called "super-fluidity". It turns out that my accepted knowledge of the universe, that matter can exist in solid, liquid or gaseous forms, is wrong.

It turns out that certain elements, Helium is one I think, when cooled, enter into a very weird state at very close to absolute zero. It's one of those very strange situations, and reminded me of the Heisenberg Uncertainty Principle, in that it is completely off the wall strange and completely unintuative.

Pretty interesting though. I've included a short video below.
