In the absence of significant gravitational or other external forces (like air resistance or container forces), the shape of a liquid is determined primarily by surface tension. Surface tension causes the liquid surface to contract to the smallest possible area.
Water drop in space is spherical because in the absence/reduced effects of gravity, the forces governing the objects are all the same and therefore the drop
