1. The mentalist called 2 spectators who do not know each other. The mentalist 1st spectator about his family and school and his/her hobbies. And the mentalist also asked the 2nd spectator roughly the same questions. By the end of the show the mentalist ask the 2nd spectator " So what is the 1st spectator's grandfather's name and the 2nd spectator said " John " ( or something ) " This is surprising . The mentalist never asked about the 1st spectator's grandpa's name.

2. TV show : The mentalist asked the audience to hold their own keys in their hands. And after they opened their arms, the keys have been bent slightly. Some people called to the TV studio and confirmed that infact their keys have been bent too and can't be used anymore. Is this a fraud ?

Define "fraud". Are at least some of the keys bent? Yes. Are there stooges in the audience? No, at least not in the way it's usually done. Were the keys bent through the mental powers of the performer? Doubtful.

:pepper:

Rgranville, I know about PK key or spoon bent as Banacheck or Osterlind show on their Dvds. Is it possible that this is just pshylogical thing ?
