Well....I'm not worrying about it...I was just thinking if it was possible to ask a person to concentrate and try to receive a word you are transmitting...then you can reveal a printed ( I mean : IN PRINT) prediction with that word being predicted). That would be a mentalist fooler

)
My idea would be an electronic device that has voice recognition so it can write what you spell and something like a printer...all incorporated in one little device.
So when the spectator say the word you can repeat it:
Hero ( than you make a little pause...in this time the device recognise the word...the word is written and you print it with the device on the paper after the message: I predict that you will receive my word corectly. The word will be: ...)...Did you just pick a word at random or you fell that that is the word to say...etc
I don't know if that would be possible and I know it would be pretty expensive but it would be awesome.
The viewers of The Mentalist that saw the episode with the NW and rembered it would be like: WTF? and the mentalists the same...he he :p
