WebMay 23, 2024 · F. Fan et al., Phys. Rev. Lett. (2024) When a narrow tube is inserted into a bed of vibrating grains, the granular material rises up inside the tube, much like a liquid climbs through a thin straw. For liquids, this capillary, or wicking, action results from attractive interactions between the liquid molecules and the tube walls. WebMar 12, 2024 · As a science teacher, I always explain kids about how water rises in a capillary tube: Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules. We know that surface tension is the cohesive forces between molecules.
