Three players in a line across the pool.
The ball is held by a player in one of the ends who passes it to the player in the center position.
The player in the center position passes to the player at the other end.
Than the center player changes places with the player holding the ball.
Then he passes the ball back to the new center player, who passes it back to the player in the opposite side.
Again, after receiving the ball, and placing it on the water, the players change places and start the rotation all over again.
