Nefesch - BlackoutBlackout, is a technique that will allow you to make any revelation through a spectator's phone, the revelation is made by any friend from the spectator that he chooses to call, the spectator's friend can be miles away, you have never met any of them and yet the revelation is accurate.
The description is this simple:

1) You ask a spectator to think of anything they want: a playing card, the name of a person, a word, etc. You can use it as a remote view type of effect, you can perform any routine you want, a book test, a magazine test, a newspaper test, etc.
2) You announce to your spectator that you will NOT reveal his thought; his thought will be revealed by any of the spectator's friends instead.
3) You ask your spectator to take his own phone out of his pocket and he is asked to call ANY of his friends.
4) Once the call has gone through you ask your spectator to tell his friend that a mentalist wants to speak to him.
5) You speak to your spectator's friend in front of everybody; so all the audience can hear the full conversation in which you ask him to reveal aloud the spectator's thought. If you want you can have the full conversation in speaker the whole time.
6) The spectator's friend reveals the spectator's thought PERFECTLY.
