Objects can sink until buoyant force balances gravity {floating}|. Displaced fluid and object both want to occupy same place, so object is at equilibrium when fluid force pushing down equals object force pushing down. Object that floats is less dense, including air spaces, than fluid. Submarines, fish, boats, balloons, and ice cubes demonstrate buoyancy. If floating-object mass center is not along buoyant-force line, object rotates around mass center.
