This file is a closeup of photo of superfluid helium, shown in black-and-white at right:

The liquid helium is in the superfluid phase. As long as it remains superfluid, it creeps up the inside wall of the cup as a thin film. It comes down on the outside, forming a drop which will fall into the liquid below. Another drop will form - and so on - until the cup is empty.

Thus, the helium shown is not only liquid, but has been cooled to the point of being in a superfluid state (helium-II).
