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".
Galilean Relativity Galilean invariance or Galilean associatively states which the laws of motion are the similar within all inertial frames. Galileo Galilei first define this
