The performer borrows a watch from any spectator and places it into the folds of a handkerchief. Immediately the watch changes into a small key which is given to the spectator to hold. The magician now produces and hands a small burlap bag that is tied with a drawstring to the spectator. The spectator opens the bag to find it contains a beautiful mahogany box that is locked. The performer points out the key that the watch changed into. The spectator unlocks the box and finds his own borrowed watch inside !
