2 cards are selected, 1 red and 1 blue back card. The blue card is placed face up with some red back cards. Quickly, its face changes to match the face of the other selection. the original card now found face up in another group of cards, thanks to carvey the invisible rabbit. the card is turned face down with the others, mixed, so no one will know which one it is now. However, to the amazement of everyone, the selected card now has a complete full cut out of a rabbit through it. the actual rabbit that fits the cut out is found, fits the empty space perfectly. it is repeatable with different cards.
