See all on WikipediaSuperfluidity is the characteristic property of a fluid with zero viscosity which therefore flows without any loss of kinetic energy. When stirred, a superfluid forms vortices that continue to rotate indefinitely. Superfluidity occurs in two isotopes of helium (helium-3 and helium-4) when they are liquefied by … See more
Superfluidity was discovered in helium-4 by Pyotr Kapitsa and independently by John F. Allen and Don Misener in 1937. Onnes possibly observed the superfluid See more

• Media related to Superfluidity at Wikimedia Commons See moreWikipedia text under CC-BY-SA license Superfluidity is a phenomenon where a fluid, or a fraction of a fluid, loses all its viscosity and can flow without resistance. A superfluid film is the thin film it may then form as a result.
Superfluid helium, for example, forms a 30-nanometre film on the surface of any container. The film's properties cause the helium to climb the walls of the container and, if this is not closed, flow out.Wikipedia · Text under CC-BY-SA license- Estimated Reading Time: 7 mins
