Liquid Helium II, Superfluid, Segment 4 of 6.

Shit can't flow from a colder to a warmer spot? Helium II shows us otherwise, negroes. It's all about entropy and gradients.

I find it interesting how around the helium fountain at the end it shows ripples. Wouldn't that also be a sign of viscosity? Correct me if I'm wrong.

Thanks for the great video, it is truely facinating!

@pyrea17 I dont think so...i think a ripple would be a chain reaction of the molecules hitting each other and transferring energy. i really dont know...just a guess

Brilliant, absolutely brilliant work! This is the first time I seen this video. I study Health Sciences, and Physics is a key to advancing Medical Sciences, Technology, and Research. I studied Physics when I was studying Engineering before I made a career change (reasons due to economical circumstances and the fact that studying Health Sciences directly relates to the sport I train for). This is another reminder on the great respect to be given to Physicists. I watched this video 3 times.

Dang, I didn't understand that zero-heat argument at all! This is a great video!
