“Scotch and Soda” is a classic coin trick that utilizes a specially gimmicked set of coins — a magnetic or hollowed-out half dollar and a copper Mexican centavo. The effect involves the apparent disappearance, transformation, or transposition of one coin, often in the spectator’s hand, creating a powerful illusion with minimal sleight of hand. The trick works by using the gimmicked half dollar to conceal or “snap over” the smaller centavo, making it appear as though the copper coin has vanished or changed into a different coin. A common accessory included with the set is a “bang ring,” which helps separate the coins after the performance for resetting. Variations of this trick allow for numerous routines, such as making the copper coin reappear in an unexpected location, like the magician’s pocket. Known for its simplicity and impact, “Scotch and Soda” remains a staple in coin magic, suitable for both beginners and professionals.
