Three In A Row
Put one of the RED Aces on the bottom of the deck, so that the audience does not see. Gather the other three Aces and show them. Then ask a spectator to put one on the top, of the deck, one on the bottom, and one in the middle. Have her cut the deck, putting the bottom half onto the top half. Ask her to hand the deck back to you. Tell her you will find the three Aces, now magically together. Go through the deck and find the three Aces next to each other.
Hint: They will be near the middle.
