This device is designed to demonstrate the function of communicating vessels, that is, the level of liquid remains the same regardless of the shape of tubes.

Equilibrium tubes can also present the concepts of capillary action, when because of the small diameter of the tube the force of capillary action exceeds the force of air pressure on the water and made water level rise. In this respect the cross-sectional area is a critical factor for the results of the experiment.
