.: From Wikipedia:
Capillary action, capillarity, or capillary motion is the ability of a substance (the standard reference is to a tube in plants but can be seen readily with porous paper) to draw a substance up against gravity. It occurs when the adhesive intermolecular forces between the liquid and a substance are stronger than the cohesive intermolecular forces inside the liquid. . . . The same effect is what causes porous materials to soak up liquids. (emphasis added)

One can also do an experiment in which one turns over a cup to see if there is any milk in it. And there was. You were so cute.
