capillary action
Capillary action or capillarity (also known as capillary motion) is the ability of a substance (the standard reference is a to a tube in plants but can be seen readily with porous paper) to draw a liquid upwards against the force of gravity. It occurs when the adhesive intermolecular forces between the liquid and a solid are stronger than the cohesive intermolecular forces within the liquid. The effect causes a concave meniscus to form where the liquid is in contact with a vertical surface. The same effect is what causes porous materials to soak up liquids.

A candle wick is a wick specifically adapted for use in a candle. A candle wick works by providing a mechanism, known as capillary action, to transport the fuel, typically melted candle wax, to the flame. When the liquid fuel reaches the flame it then vaporises and burns.
