The Bat works on a different principle to the Raven, you can still vanish or exchange coins, but it also enables you to accomplish an exciting array of additional magic. The effects range from puzzling table stunts to psychic effects. The kinetic ring routine is one possibility. You hand out two brass rings for examination. After a moment of concentration you make the rings adhere to one another and spin the lower ring around. The rings are once again handed out and nobody can repeat your performance. You can also perform many psychic routines including the stopping of a second hand on a spectators watch.
