Hello Sara! I am happy to help with this question.
Water molecules stay close to each other as a result of existence of hydrogen bonds. Collectively, hydrogen bonds hold the substance together, this phenomenon is called cohesion. The clinging of one substance to another, which is called adhesion also plays a role. In this way, adhesion of water through hydrogen bonds to the molecules, which comprise the villi on the cat's tongue, helps counter the downward pull of gravity. As a result, such a phenomenon as adhesion helps drops of water stay whole and attached to each other. At the same time, cohesion allows drops to be transported against gravity.
