The mentalist asks anyone to chose any page and then any word from a regular unprepared book, they can even change their mind.
The mentalist asks them to imagine that their freely chosen word is their new Facebook password and the freely selected page their new credit card PIN.
The mentalist is then able to cleanly divine both!
No strange procedures are used to select the page or word. They truly have a free choice. No forces of any kind are used.
Everything is examinable, there is nothing to find.
An anytime, anyone, anyplace mind reading miracle.
