- Because water is liquid at much too high a temperature. Helium is only superfluid near absolute zero. To have a superfluid, you need the quantum wavelength of the atoms given the environmental decoherence to be longer than the separation between the atoms, so they can coherently come together.Learn more:Because water is liquid at much too high a temperature.

Superfluidity is the characteristic property of a fluid with zero viscosity which therefore flows without any loss of kinetic energy.
