A 21st century kinetic toy with a unique mathematical shape.

Overview

PhiTOP

The PhiTOP is a 21st century kinetic toy with a unique mathematical shape. Spin it fast and it seems to defy gravity as it stands upright on its narrowest point. Spin it slow to create the illusion that the top is made of pulsating gelatin as the reflective surface provides a miniature light show. The PhiTop's distinguished pedigree comes from applying the Golden Ratio to an ellipse.

Designed by Professor Keneth Brecher, the PhiTOP has captured the imagination of renowned physicists as well as young children.
