When helium is cooled to a critical temperature of 2.17 K (called its lambda point), a remarkable discontinuity in heat capacity occurs, the liquid density drops, and a fraction of the liquid becomes a zero viscosity "superfluid".

That's because soft drinks are nothing like the superfluid helium shown in this video. ... In superfluid helium, the frictionless film slithers over the whole container, creating a sort of arena through which the superfluid can flow. If the liquid has somewhere to fall after it climbs out of the dish, it will drip from...

What Are Superfluids ? Superfluids are, like superconductors, related to the behaviour of materials at very low temperatures. Superfluids can only observed at much lower temperatures than superconductors, Helium-4 doesn't display superfluid-behaviour until nearly below 2K. and these temperatures are not easy to reach.

A superfluid is a liquid that flows without viscosity or inner friction. For a liquid to become superfluid, the atoms or molecules making up the liquid must be cooled or "condensed" to the point at which they all occupy the same quantum state.

A Site on the Properties of Superfluid (He II, Superfluid of Helium) ... SUPERFLUID HELIUM (He II, Superfluidity) ... Other strange properties of superfluid include the Rollin film, mechanocaloric effect and fountain effect. The two fluid model postulated by Landau and Tisza is the most accepted theory for predicting...
