Adairs Window Prediction
A card is freely selected from an examined, shuffled deck. Performer slides it into a small board folder which has a window cut-out on its front. Spectators see the back of the chosen card at all times.
Moments later when the card is slowly and visibly removed, there printed boldly within the window area (plain & blank before) is a written prediction of a card. When the selected card is reversed it matches the prediction.No forces (the choice is 100% free and fair) and easy to do.
