Here is your easy mentalism tie in. Have the spectator write down a secret two digit number.
Tell them you are going to try and get a psychic impression of what the number is... obtain their
secret number using whatever method. Fill out the grid, pretend that they should see their number
somewhere on the grid. Tell them you are going to try and issolate their number... but then act
like you are sensing that there is something wrong... ask them You do see your number here corrrect?
No they don't. Magician failed. But then pretend you understand what happened. Reveal the
number.
