Explanation:
Detailed explanation-1: -This is possible thanks to the surface tension of the water.
Detailed explanation-2: -Adhesion of water to the walls of a vessel will cause an upward force on the liquid at the edges and result in a meniscus which turns upward. The surface tension acts to hold the surface intact. Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules.
Detailed explanation-3: -The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a “sticky” liquid.
