Demon Rod and Beads

This is a very visual trick. The magician shows a bamboo rod with four beads: two are on a short cord and two on a longer cord. As one of the beads on the short cord is pulled down, the other cord magically becomes shorter. This can be repeated and the audience is convinced that the cords must be joined. At that point the magician pulls the rod apart into two pieces, so proving that the cords are not connected in any way. However, when the rod is reassembled, the trick can immediately be repeated. Once the possession of Cambridge magician Claude Perry. A Davenport advertisement for the trick is also illustrated.
