The Jastrow Illusion in Magic: A Treatise on the Boomerang Illusion
Visual illusions are a natural form of magic because our mind cannot help being deceived by some geometrical patterns. The Jastrow Illusion is one of the most common visual illusions. In this natural deception, two boomerang shapes seem to be different in size, while they are in fact identical.
The Jastrow illusion is also known to magicians as the boomerang illusion.
Magicians tend to underestimate the power of this simple trick. This illusion is mainly used by children’s entertainers and can be found in beginner’s magic kits. This book shows how magicians can use this illusion to create entertaining magic for audiences of all ages.
The Jastrow Illusion in Magic provides an in-depth review of the psychology of this illusion. Readers will learn how it psychologists discovered this illusion and how they still use it in the laboratory. The book also contains a template for the most deceiving design for a close-up boomerang. The book delves into the history of the use of this principle in magic. The last part of the book explains how to develop your magic routine with this quirky prop.
The Jastrow Illusion in Magic calls for a come-back of the boomerang illusion in magic and will inspire magicians to develop their own version.
