Water has two important qualities: cohesion and adhesion. Cohesion means that water "sticks" to itself, forming drops on a flat surface. Adhesion means that water sticks to other things, such as copper pennies. The water adheres to the coin and coheres to itself, forming a bulbous drop of water on the coin.
