This is due to the surface tension of water. Because of the surface tension , the drop tends to have minimum possible surface area, and the shape which is possible with minimum surface area is "spherical shape".

The force of attraction between the molecules of water is higher.
Because of surface tension, every thing in the universe wants to achieve stability,they do that by lowereing their energy.which in this case is the surface energy.a sphere offers lowest surface area yet a very large volume
