 CONT: In the basement with the Ouija board, Regan is playing with a  table tennis paddle and ball. She puts the ball under the paddle and  rests it on the table when her mother brings the Ouija board.  Clearly the ball is under the paddle as evidenced by the angle of  the paddle. In the very next shot, the paddle is flat on the table  and the ball has disappeared. In the next shot, the ball reappears  as demonstrated by the angle of the paddle.
