Abstract
A method of playing with a ball and a U-shaped conduit having a uniform circular cross-section throughout its length and having opposite open ends so that either open end can discharge or capture the ball. The method comprises: holding the conduit so that the open ends are upright and the ball is in the center of the conduit, starting the ball moving back and forth by moving the conduit sidewise, as the ball rolls inside the conduit, moving the conduit in the opposite direction creating momentum on the ball so that it will travel farther up the opposite side of the conduit, and repeating the above steps until the ball is released from the conduit through an open end. The method may be carried out by a single player who repeatedly releases and captures the ball or by multiple players who take turns capturing and releasing the ball.
