That's quantum physics on an everyday scale! (if you can call -271 C "everyday"). The whole mess of liquid acts like a single quantum object, a giant flowy particle.
If you put it on a turntable and start to spin the beaker, the liquid helium will stay perfectly still until the beaker hits a certain speed, then it will all start spinning as one object.
I think quantum phenomena has a 50/50 chance to get credited to Jesus or blamed on Satan.
if i wasn't already going to 5 this, your comment would have earned it.
a way over qualified high school science teacher i had told us about helium in a superfluid state. not sure if there is video of it, but he said when mixed up like water in a glass with a spoon, it spins in multiple vortexes because that apparently is more efficient.
I have a friend who's PhD. dissertation was on how superfluids and superconductors were analogous. The discussion was interesting (though largely over my head) so it's supercool to see in this in action.
