condensed matter - physics of the beaker experiment for superfluid helium


here is an illustration and explanation of the beaker experiment over superfluid helium:


enter image description here


So, according to this experiment, can anyone say what is the cause? I mean the superfluids are disconnected physically (compare with two tanks of fluid which are disconnected or connected through a way) but they tend to make equi-level heights. what is the basic physics behind it?!!
