A great comedy prop to add to any act!
An assistant is brought up from the audience. He is asked to take the magic wand from you and wave it. He takes the wand, but finds that there are now two wands. One in his hands and one in yours. As you tell him that he is waving the wrong wand you have him take the wand in your hand. As he takes the wand, it splits in two and goes off with a loud bang!
