Houdini Bead Escape

A black wooden bead representing Houdini is shown with two cords running through the center. One cord is tied around the black bead, trapping it on the cord. A yellow bead is threaded on one side of the black bead. On the other side, a white bead is threaded on. The magician gives the cords a quick tug, and the black bead penetrates the cords and falls to the table, leaving the other two beads on the cord.
