Surface tension is the property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules. This force causes the liquid surface to contract to the minimum possible surface area for a given volume, which is a sphere.
Raindrops are spherical in shape because of the phenomenon called
