The Jastrow illusion is known to magicians as the boomerang illusion. Two boomerang-shaped ring segments seem to be of different sizes but are in fact identical.
Magicians tend to underestimate the power of the Jastrow illusion magic trick. Its use in magic is limited to children’s entertainers and magic kits. This illusion is more powerful than it seems at first sight. A recent viral video shows that its deceptive power is as strong as it was when first discovered almost 150 years ago.
