Superfluid helium climbs walls against gravity
Cooled to near absolute zero, superfluid helium flows without friction, astonishingly climbing container walls and defying gravity in a quantum marvel.
Imagine a liquid that flows without any friction, so freely it can climb the walls of its container and even spill over the top! This is superfluid helium, formed when helium-4 is cooled below 2.17 Kelvin, transforming it into a quantum marvel. Its atoms move in perfect harmony, behaving like a single entity and eliminating internal resistance.
