This process validates the cohesion-tension theory of transpiration, and the synthetic tree should also be a useful platform for the study the properties of metastable liquids and a starting point ...

Capillary action is the movement of water within a solid, but porous, material due to the forces of adhesion, cohesion and surface tension. Water molecules like to cling to each other.

Cohesion is the attraction of like molecules to one another. In this experiment, we're examining like H20 molecules in the water drops. Surface tension describes the cohesion between water molecules.
