- 1). Prepare for the trick by separating a deck of cards into two smaller decks: one of only black cards and the other only red cards.
- 2). Lay the decks out side by side on a table and have the volunteer choose a deck.
- 3). Have a volunteer pick a card at random from the deck he or she chose.
- 4). Have the volunteer memorize the card and show it to the audience, and tell him or her not to show it to you or tell you what it is.
- 5). Have the volunteer place the card into the other deck at any location.
- 6). Shuffle this deck several times.
- 7). Look through the deck. The volunteer's card will be a different color than the other cards in the deck.
