PhiTOP

£19.93


 

The PhiTOP is an elegant scientific, mathematical, artistic and aesthetically pleasing object that brings joy to the eye, hand and mind.

A polished aluminium prolate ellipsoid with height-to-diameter ratio Φ ~ 1.618…, also known as a Golden Ellipsoid, the PhiTOP demonstrates several fascinating behaviours - when spun like a top, it will jump up and spin on its narrow end for an impressively long time, and it will reflect light, create sounds and react to magnets in mathematically interesting ways.

Set includes PhiTOP, acrylic display stand, instruction booklet and round mirror for spinning the PhiTOP on. Visit the PhiTOP website for more information.
