You put your finger through a large square cut out of a blue-backed playing card. Instantly the card turns red and the hole you just saw fingers go through somehow no longer exists. The black hole is now just a piece of black tape that is peeled off of the card. A real visual puzzle!
To make the gimmick you will need the usual card-gaffing supplies and some arts and crafts to construct it.
