- 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. 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.physics.stackexchange.com/questions/38124/why-…In an ordinary liquid such as water, the thermal disorder ensures that the atoms (or molecules) are distributed over the different (quantized) states available to them in such a way that the average velocity is not quantized; thus, when the container rotates and the liquid is given sufficient time to come into equilibrium, it rotates along with the container in accordance with everyday experience.www.britannica.com/science/superfluidityIn fact, it flows so easily that friction does not change the way it flows; it has zero viscosity. Because of this, it can actually flow out of a container, like a bowl, even when the bowl is not tipped so the liquid can spill out. It stays still when its container is spun, instead of starting a whirlpool like when a sink full of water is drained.simple.wikipedia.org/wiki/Superfluidity
