Superfluid - Definition Of Superfluid - Physics
One effect of this is that the viscosity of superfluid helium-4 becomes zero, meaning that normal rules of surface tension, such as capillarity, are no longer obeyed. A superfluid in a glass tube will literally "crawl" up the side of the tube in a thin film because of this property. ... Read Article
