Product Description

A most intriguing optical illusion. Two different colored plastic pieces shaped like boomerangs are shown. The upper boomerang is obviously shorter than the one below. Then the smaller one is stretched and shown to be longer. Finally, both are shown to be exactly the same.

To see an animation of the effect, enlarge the picture.
