Contents (Andrew Pinard):

1. A selected (court) card is revealed and then the middle is knocked out.
2. A card is selected and then lost in the deck. A special spinning tray is displayed. An indifferent card is removed from the deck and placed on the tray. The tray is placed into motion and when it stops it is revealed that the card has transformed into the selected card.
