- Superfluidity is a characteristic property of a fluid with zero viscosity1. This means that the fluid flows without any loss of kinetic energy. Superfluidity is only observed in liquid helium cooled to near absolute zero2. When stirred, a superfluid forms vortices that continue to rotate indefinitely1.
