Smarties by David Jonathan and Kevin Aust

Created by: David Jonathan, Kevin Aust

Deqode is a cutting-edge QR code and barcode prediction system designed for close-up and parlour magic. The performer sets up a scenario where the audience imagines selecting any item from a store shelf. Without revealing the chosen item, the magician claims to have a prediction already locked in. The climax occurs when the performer reveals a barcode on a prop that, when scanned, directs to the exact item the spectator was thinking of—such as Smarties in this demonstration. The system works seamlessly on both iOS and Android devices, offering real-time control over scanning destinations. This trick is perfect for magicians who want to blend technology with mind-blowing predictions in an everyday context.

Effect

The Smarties trick is a barcode-based prediction effect. A spectator imagines any item from a store, such as Smarties, without revealing it out loud. The magician claims to have already predicted the choice. A barcode on a prop is then scanned, confirming it matches the spectator's thought-of item. The moment feels impossible because the spectator never verbalized their choice.

Full Details

The trick uses a system called Deqode, which allows the magician to control where a barcode or QR code scans. It works on both iOS and Android devices. The performance involves a relatable scenario, like shopping in a store, making the effect more engaging. The magician never asks the spectator to say their choice aloud, increasing the mystery. The reveal happens when the barcode is scanned, proving the prediction was correct.

Who Should Consider the Trick

This trick suits magicians who perform close-up or mentalism. It works well in casual settings, like parties or street magic, because it uses everyday objects (barcodes and phones). It is also good for performers who like interactive, technology-based magic. The method is easy to learn, making it accessible to beginners, but the presentation can be adapted for experienced magicians.

Difficulty

The trick is not difficult to perform. The method is straightforward, and the setup is quick. The main challenge is presentation—making the scenario feel natural and building suspense before the reveal. The handling is simple, so even new magicians can perform it confidently with minimal practice.

What Magicians Say

MurphysMagicSupplies describes the trick as a "versatile prediction system" that works in real time. They highlight the strong audience reaction, especially when the barcode scans correctly. The performance relies on misdirection and playful banter to enhance the effect. The creators emphasize that the trick is easy to carry and use, making it practical for regular performances.

The video transcript shows how the magician builds suspense by pretending to write the prediction in a notes app before revealing the barcode. The spectator's reaction—disbelief when the barcode matches their thought-of item—proves the trick's impact. The magician also jokes about the audience's skepticism, reinforcing the impossibility of the effect.

Overall, the Smarties trick is a strong, easy-to-perform prediction effect that works well in many performance settings.
