      You can try it yourself by adding a drop of dish soap to some water. Capillary action would still work and the water would evaporate long before covering the entire floor.

        Capillary rise depends on surface tension, gamma. If surface tension was 0, there would be no capillary rise. Soap decreases surface tension, but it’s not 0.

          Oh nevermind then. I just looked it up and came across the so-called Rollin film. I don’t know if that only appears in helium or if superfluid water would be subject to that effect as well. I wonder how that would impact its behaviour.
