Most magic tricks aren't powered by some mystical force, but by real-life sleight-of-hand! Sleight-of-hand is a type of trick where you manipulate objects with your fingers and distract your audience to create the illusion that something is disappearing or transforming. One illusion you can do at home is make it look like you're turning a card into a watch. Keep reading to learn 3 variations of the card-to-watch magic trick: one where you snap it back behind your fingers, one where you fold the playing card into your hand, and one where you use magnets.

Card to Watch Magic Trick, Revealed

An illustration showing the 4 steps to a simple variation of the card-to-watch magic trick.

Hold the ends of the watch band between your thumb and index finger. Next, pinch a playing card between your index and middle fingers. With the card facing the audience, dip your hand and snap your fingers. While snapping, tuck the card behind your thumb and index finger, and release one end of the watch to dangle it.

Before you gather your audience, set up the trick. Simply fold the watch in half and hold the ends of the watch band together with your fingers.^{[1]

Using the same hand holding the watch, slip a playing card between your middle finger and your index finger. The back of the card should be facing the audience, and the card should conceal the watch you're holding.^{[2]

Remove the card from your hand while the audience is distracted. As the watch dangles from your hand in front of the audience, tell a joke or say something random, like a magic word (i.e., "Abracadabra!") to distract them. Next, surreptitiously pick up a deck of cards with your other hand. Move it toward the card hidden behind the watch and slip that card back into the deck.^{[4]

- You may need to practice this trick a lot to make it look as if you're truly transforming a card into a watch. And that's okay! Sleight of hand is tricky, but you can become great at it with time and effort.

Folding the Playing Card

1
Fold a playing card in half with the face on the inside. Make the fold from top to bottom. Then, unfold the card again and flatten it so it looks straight from a distance, like a regular playing card.^{[5]

- Use any number or face card (e.g., Jack, Queen, King, or Joker) you want. This is your magic trick!

Fold the two ends of the watch band inward over the back of the watch. When you fold the right side, leave a little bit of slack. When you fold the left side, stretch it taut so the end lies over the fold of the right side. Then, pinch the two sides between your thumb and forefinger and turn the watch so the face is towards you.^{[6]

- When you let go of the right side of the band, the watch should unfold and dangle downward, so that the watch face is directed toward your audience.
Pinch the watch and the flattened playing card together. Place your thumb on the back side of the card facing you, and position your other fingers on the front side facing your audience.^{[7]

Position your right hand just below the card that you’re holding in your left hand. Ensure your palm is facing you, and the back of your hand is facing your audience. Press your fingers together so you don't leave any gaps between them.^{[8]

As you lower the card and watch with your left hand, snag the bottom edge of the card on the fingers of your right hand to make it bend in on itself. ^{[9]

Grip the folded card in your right hand with slightly bent fingers. Gently press the card in toward your fingers on your right hand. Then, bend the tips of your fingers just slightly so you can grip the edges of the folded card.^{[10]

- Move your fingers as little as possible during this step, so your audience won't realize what you're doing with the card!
This step will cause the watch face to fall and dangle underneath your right hand. To the audience, it looks like you transformed the playing card into a watch!^{[11]

As you pull your hand away, keep your palm facing toward you so the enthralled onlookers can't see the card. Hold up the watch for them to see, and as you're doing so, use that as a distraction to tuck the card into the back pocket of your pants.

Gluing Magnets on the Playing Card

1
Mark out the width of the watch band in the center of a playing card. Measure the watch band's width with a ruler and note the measurement on a piece of paper. Subtract that number from the card's width, then divide the answer in half. Measure the half length starting from each of the card's long edges and moving toward the center. Make a vertical mark at each point you measure to, then draw a vertical line from each of those marks up and down the length of the card.^{[12]

- Example: Let's say your watch band is 1.8 cm (0.71 in) wide. A typical playing card is 6.3 cm (2.5 in) wide. Subtract 1.8 from 6.3 to get 4.5, then divide 4.5 by 2 to get 2.25. Now, draw 2 vertical lines across the length of the face of the card with a pen. Start each line at 2.25 cm (0.89 in) inward from either edge.
  - Now the center section between the two lines will be 1.8 cm (0.71 in), the same width as the watch.
Drag the blade of the X-ACTO knife lightly across the card. Avoid cutting through the card—the goal is to score it so you can bend it into thirds.^{[13]

Fill in the entire face of the card with black ink. Leave the back of the card unmarked and the way it came out of the deck.^{[14]

Glue a 3 mm neodymium magnet to each corner of the card and place the 2 remaining magnets in the center of each long edge, between the corners. Just make sure to use the magnet’s north pole on one side of the card and the south pole on the other so they stick together. Then, use super glue or another strong adhesive to get the most secure hold. Then, color the tops of each magnet black with your marker.^{[15]

Glue 2 magnets along the top and bottom of the back of the watch face. Then place 2 more magnets on top of the first ones, so they're attracted to one another.^{[16]

This glue will adhere the magnets to the playing card, ensuring that the magnets on the back of the watch and on the card line up.^{[17]

Fold the card up and center the base over the magnets on the watch. Fold the sides of the card up where you scored them, so the magnets click together into a triangle shape. The black side of the card should be facing out. Next, center the base of the card over the magnets on the back of the watch, parallel with the watch band. Press down and hold the card and the watch together firmly so the magnets adhere to the card.^{[18]

- Wait for the glue to dry completely before performing the trick.
Flatten the card so it looks like a normal playing card when viewed from the back. Next, roll up the end of the watch band with the buckle and hold it to the back of the watch with your fingers. Fold the other end of the watch band across the top of the rolled-up end, so the tip of it sticks out about 2 cm (0.79 in) over the end of the card.^{[19]

Your fingers should conceal the watch band.^{[20]

Let go of the card and flick the watch band simultaneously. The band should unravel and expose the watch face, while the card folds into a triangle along the back of the watch face. This makes it look like your card turned into a watch! To help the trick look even more seamless, wear a black shirt so the black side of the card blends into it.^{[21]
