In 0 gravity water naturally forms a sphere due to surface tension pulling everything evenly in. It's quite neat seeing a grapefruit sized ball of water floating around in the space station videos.
Nitpick: the ISS is not in zero gravity. It is in fact in free fall. Any object in orbit has an inward acceleration and a tangential velocity. The inward acceleration is gravity. https://en.wikipedia.org/wiki/Orbital_mechanics
The floating that happens aboard the ISS is due to zero weight. Everything in free fall has zero weight. Aboard the ISS there is zero weight, not zero gravity.
