- Superfluidity Uses At present, there aren’t many practical applications of superfluids. However, superfluid helium-4 is a coolant for high-field magnets. Both helium-3 and helium-4 find use in exotic particle detectors. Indirectly, researching superfluidity aids in understanding how superconductivity works.

See all on WikipediaLight behaves like a superfluid in various applications such as Poisson's Spot. As the liquid helium shown above, light will travel along the surface of an obstacle before continuing along its trajectory. Since light is not affected by local gravity its "level" becomes its own trajectory and velocity. See more
