First, water drops can only be spherical in zero-G with no wind.

The properties of cohesiveness of water causes water drops to attempt to form spherical shape when not in contact with other matter.

Water droplets are spherical due to the surface tension phenomena.

Surface tension is caused by the attraction between the molecules of the liquid, due to various intermolecular forces. In the bulk of the liquid each molecule is pulled equally in all directions by neighboring liquid molecules, resulting in a net force of zero. At the surface of the liquid, the molecules are pulled inwards by other molecules deeper inside the liquid, but there are no liquid molecules on the outside to balance these forces.
All of the molecules at the surface area therefore subject to an inward force of molecular attraction which can be balanced only by the resistance of the liquid to compression. Thus the liquid squeezes itself together until it has the lowest surface area possible.

As mentioned above, to have minimum surface area the water droplets will be spherical in shape

Becouse surface tension forces tend to decrease the exposed surface area of the liquid by assuming a spherical shape which allows a given volume of material to have smallest possible surface area

In another words ----> the spherical shape is the smallest surface area that can any material take (that happens due to surface tension forces)

i hope u got ur point from my explanation
