Description:
This picture was taken in my shower. The tile is sealed with a sealant to keep out mold and unwanted scum. Water is a polar molecule, composed of two hydrogen atoms bonded to a single oxygen atom. Water molecules like to stick to one another, like small magnets. This is called cohesion. Some substances are not at all attracted to water, and even repel it. These include sealants, oils, fats and waxes, all of which are called non-polar substances. The chemical structure of the sealant prevents water from penetrating to the surface of the tile. Because the sealant itself is hydrophobic (literally "fears water"), the forces of adhesion (when water spreads out) are much less than the forces of cohesion. So, water is more likely to stick to itself, and bead up higher and rounder than if the tile was not sealed.
