Capillary action (sometimes capillarity, capillary motion, or wicking) is the ability of a liquid to flow in narrow spaces without the assistance of, and in opposition to, external forces like gravity. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube, in porous materials such as paper, in some ...

The process by which liquid is drawn into the joint by molecular attraction. Capillary action can operate against the force of gravity. Brazing and soldering rely upon capillary action to draw the filler material into the joint.

Also called capillarity, the name given to various surface tension phenomena in which the surface of a liquid confined in a narrow-bore tube rises above or is depressed below the level it would have if it were unconfined.
