The -271°C Quantum Anomaly 🧪🥶

The quantum physics of a perfect superfluid. 🧪🌡️ - Liquid Helium

This iconic archival demonstration shows Liquid Helium-4 transitioning into a superfluid state. Lacking any viscosity, the fluid escapes its environment via a climbing phenomenon called the Onnes Effect. In the second half, the superfluid effortlessly leaks through a porous filter—a channel so tightly packed that standard liquids are completely blocked by surface tension.
