Rulers by Père Alex & Marchand de trucs

Bring a timeless optical illusion to your performances with Rulers, a clever and elegant visual effect inspired by the classic paradox made famous by psychologist Joseph Jastrow. In this intriguing routine, the magician introduces two wooden school rulers, one marked in centimetres and the other in inches. When placed side by side, the measurements seem to match perfectly. But with a simple reversal, the rulers appear to change size, creating a startling new comparison that looks impossible. In the finale, the audience discovers that both rulers are actually the same length.

Designed to be clear, immediate, and visually striking, this effect delivers a memorable moment of surprise that works beautifully in close-up settings. The presentation blends humour, logic, and mystery, making it an engaging piece for magicians who appreciate smart, classic illusions with a refined finish.

What’s included: a specially crafted wooden box, two wooden rulers with different measurement markings, and an instructional video in French explaining the method.
