The Effect
A playing card is shown with a small hole cut through its centre.
A large coin is displayed beside the hole, making it obvious that the coin is far too big to pass through.
The card is folded around the coin and, with one quick pull, the coin appears to squeeze directly through the tiny opening.
Before You Begin
You will need one playing card, a coin, scissors or a craft knife and a cutting mat.
Take care when preparing the card. Younger magicians should ask an adult to help with the cutting.
The illusion depends on keeping the secret slit hidden and maintaining the correct viewing angle throughout the routine.
Watch the Tutorial
Watch the complete performance and explanation before making the gimmicked card.
Cut the Small Hole
Fold the playing card in half.
Cut a small semicircle from the folded edge so that opening the card creates a round hole in the centre.
Make the hole clearly smaller than the coin you plan to use.
Add the Secret Slit
Cut a horizontal slit across the upper part of one half of the card, roughly one centimetre below the edge.
The slit must be wide enough for the coin to pass through smoothly.
Keep the cut neat so it remains difficult to notice during the performance.
Show the Impossible Challenge
Display the card and the coin side by side.
Let the audience clearly see that the coin is much larger than the hole.
Do not draw attention to the upper part of the card where the secret slit is hidden.
Secretly Load the Coin
Fold the card with the slit facing toward you.
Insert the coin between the two halves as though placing it behind the small hole.
Secretly slide the coin through the hidden slit so part of it emerges behind the card.
Hold the exposed portion securely with your thumb.
Show the Convincer
Briefly angle the top of the folded card toward the audience.
From their viewpoint, the coin appears to be trapped inside the centre of the fold.
Keep the exposed part of the coin covered by your thumb and avoid showing the back of the card.
Pull the Coin Through
Hold the folded card facing the audience.
Pull the coin downward quickly while keeping it pressed against the card.
From the audience’s angle, the coin appears to stretch and pass directly through the tiny central hole.
Why the Illusion Works
The spectators assume the coin remains trapped between the two halves of the folded card.
In reality, the hidden slit allows most of the coin to move behind the card, where it can be pulled downward without passing through the small hole.
The card blocks the audience’s view of the secret route, while the fast downward action completes the illusion.
🎩 Magic Tip
The brief top view is a powerful convincer, but keep it short. The longer the card is displayed, the greater the chance that the hidden slit or exposed coin will be noticed.
Performance Tips
Keep the slit side of the card facing you throughout the routine.
Display the coin and small hole clearly before folding the card. The stronger the apparent impossibility, the stronger the final penetration will feel.
Use one smooth downward pull rather than several small tugs.
Once the illusion has registered, casually place the card aside and continue into another trick. A smooth transition keeps the audience focused on the magic rather than the prepared prop.
Common Mistakes
Do not make the central hole too large. It should look obviously smaller than the coin.
Avoid cutting the secret slit too close to the edge, where it may tear during the performance.
Keep the card angled correctly so spectators cannot see the coin emerging from the back.
Do not pull the coin slowly. The penetration looks strongest as one clean, confident movement.
Practice Exercise
Practise loading the coin through the slit without looking directly at your hands.
Rehearse the brief top display in front of a mirror so you know exactly how far the card can be tilted safely.
Repeat the final pull until the coin remains flat against the card and does not catch on the slit.
