The magician shows a small booklet. On its cover there are the drawings  of three common objects: a telephone, a pen, and a key. A spectator  names any one of these objects. The selection is absolutely free, and  the spectator may even change his mind if he likes. Once the object is  named, the magician starts flicking through the pages and a fascinating  animation will commence. The picture of a hand is seen to come out of a  window and go towards the pictures of the three objects, then it picks  up… exactly the object that the spectator had freely chosen!
 
A cool little effect with a nice animation that will baffle your spectators!
