Capillary rise is one of the most well-known and vivid illustrations of capillarity （shown in Figure 1）. Knowledge of capillarity laws is important in oil recovery, civil engineering, dyeing of textile fabrics, ink printing, and a variety of other fields. It is capillarity that brings water to the upper layer of soils, drives sap in plants, or lays the basis for the operation of pens [1-10].
