The Effect
A spectator signs a borrowed coin before it is apparently slammed straight through the bottom of a sealed soda can.
Moments later, the can is opened and the signed coin is heard rattling inside before being poured back out.
This is one of the strongest impromptu-style coin tricks you can perform.
Before You Begin
You'll need a full can of carbonated soda, a marker pen and a coin that will just fit through the can opening once the ring pull has been opened.
Practise the handling with an empty can first so you become comfortable with the secret movements before performing with a full drink.

Gather the Props
You'll need a carbonated drink can, a marker pen and a coin that fits through the can opening.
A slightly smaller coin usually works best.
Borrow and Sign the Coin
Borrow a coin and ask the spectator to place a small signature or mark on it.
This makes the final revelation much stronger.
Display the Can
Hold the can so the base faces away from your audience.
Explain that you will attempt to slam the coin through the metal.
Slam the Coin
Strike the base of the can with the coin.
The audience hears the impact while the coin secretly remains hidden on the bottom rim of the can.
Show Your Hand Empty
Immediately pull your striking hand away and display it empty.
The audience believes the coin has entered the can.
Transfer the Can
Tilt the can into your opposite hand and casually show the first hand empty.
The hidden coin remains concealed during the transfer.
Display the Can Base
Rotate the can so everyone sees the bottom.
Since the coin has secretly dropped into your palm, the base appears completely clean.
Create the Rattle
Secretly slide the coin halfway up the side of the can with your thumb.
A gentle shake creates the convincing sound of a coin already inside.
Position the Coin
Continue sliding the coin to the top of the can.
Keep it hidden beneath your thumb directly over the unopened drinking hole.
Load the Coin
Open the ring pull.
As the fizzy drink foams, push the coin into the opening. The escaping soda disguises the secret action perfectly.
Reveal the Signed Coin
Pour the drink out until the signed coin appears at the opening.
The audience sees their own marked coin emerge from inside the sealed can.
Performance Tips
Keep the base of the can angled away from spectators throughout the early part of the routine.
Don't rush after the apparent penetration. The pause helps sell the idea that the coin is already inside.
The fizz created when opening the can provides excellent natural misdirection for the secret load.
This trick works particularly well in bars, parties and other casual settings where drink cans are naturally available.
