Newton's third law of motion. The turning of the sprinkler head is the equal and opposite reaction to the water leaving the sprinkler nozzles. The water goes out and the sprinkler nozzle is pushed backward, turning it in a circle because the arm is attached to the middle of the sprinkler. The higher the water flow, the faster the sprinkler spins.
