Slide an inconspicuous ring around your middle finger.
Slide a matchstick through the ring with the red tip facing your palm. There should be an equal length of matchstick on either side of the ring.
Shuffle a deck of cards on a table and smoothly slide the first card between your middle finger and the matchstick.
Lift your hand up with the palm facing down, parallel to the table. The card will float up with your hand.
Smoothly remove the card and match, and pocket the match. Invite spectators to inspect the deck, your hand and ring if desired.
