The capillary equilibrium tube is a thought provoking demonstration. Normally, if the arms on this device were all the same thickness, water in connected tubes would reach equilibrium at the same height because of equal atmospheric pressure. However, with this device, the cross-sectional area of each tube alters the final height of the water in that tube.
