The performer now removes a prediction from an envelope that has been in view the whole time - it states, Somehow you thought of the Four of Spades! The only card that wasn't there! The spectator is speechless. Want to know why it's called Project-X? asks the performer. The spectator nods. The performer hands the envelope to the spectator. Inside is a single playing card with a big, black X on its back. It is the Four of Spades!
