To view the original source information, use the "Learn more" links.A superfluid is a special type of fluid that has zero viscosity so that no kinetic energy is lost when it flows. An interesting consequence is that superfluids climb or “creep” up container walls. Liquid helium-3 and helium-4 are examples of superfluids. Some Bose-Einstein condensates and ultracold atomic gases display superfluidity.sciencenotes.org/fluid-definition-and-examples/Here are other superfluidity examples:
- Superfluid helium-4
- Superfluid helium-3
- Some Bose Einstein condensates as superfluids (not all, though)
- Atomic rubidium-85

Superfluidity - Wikipedia
Superfluidity 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 cooling to cryogenic temperatures. It is also a property of various other exotic states of matter
