Hi , I saw before a mentalist tells one of the audience to come out to the stage and says to him that imagine you stand up on the library then take any book imaginary , name any name to this book , open any page and named that page number then name any word in your mind , the volunteer says cat for example , finally the magician tell him to bring out the predication from his front pockect it matches ( cat) ! .. Can anybody explain that ! Stooges ? Fake ? Real ? I am confused really .. the second part : a prediction placed on the table with 6 cards shown to the spectator every card have different word then the mentalist tells him to choose any number from 1 to 6 then he counts to the chosen card , the chosen card matches the prediction ! I hope to help me thank you
