A funny way to make a prediction! A card is inserted face down in a special machine with several buttons located at the front. This machine allows a corner of the card to always be in full view. A playing card is chosen by the spectator, but it does not match the prediction in the machine. Not a problem, the magician simply imputes the correct card with the buttons on the machine, and when the large card is removed, it has changed into the spectator's selection!
