Explain how the properties of water allow water to form on a penny when using a dropper.
Gravity flattens the droplets, cohesion holds the droplets together, and adhesion holds the drops on the surface of the coin. The cohesive force is the pull of the water molecules on themselves. Each successive drop sticks to the water that's already on the coin. We often call this cohesive force “surface tension”.
