cohesive forces are greater than adhesive forces
the attractive forces between water molecules and the wax on a freshly-waxed car (adhesive forces) are quite weak.
however, there are strong attractive forces (cohesive forces) between water molecules.
the water molecules are only weakly attracted to the wax, so the cohesive forces pull the water molecules together to form beads .
