Did you know? When helium-4 is cooled below 2.17 K (-271 °C), it enters a strange and fascinating state called a superfluid. In this quantum state, helium-4 has zero viscosity, meaning it can flow without any friction at all.This allows the liquid to creep along surfaces and even climb the walls of a container, forming an ultra-thin film that defies gravity. #SuperfluidHelium, #QuantumPhysics, #DidYouKnow, #MindBlown, #ScienceFacts, #PhysicsIsCool, #Helium4, #RollinFilm, #LiquidHelium, #DefyingG

Rolling Ball Fountain https://www.physicsfunshop.com/search?keywords=fountain This miniature kugel fountain features a glass sphere that sits on a socket of precisely similar shape, and is suspended on a very thin (less than half a mm) film of moving water which greatly reduces friction. The velocity of the water in the thin layer slows as it spreads out via a hole in the socket, and this hole is offset from the center so that the interaction with the water stream sets the ball spinning.
