Water tends to cling to things because of its chemical properties. The oxygen in water carries a slightly negative charge where as the hydrogen carries slightly positive charges. Because of this, the molecules of water tend to cling together better, creating a high surface tension. It is this surface tension that helps water bead together on objects like glass.
