Origin United States
Dimensions 2 x 1 Inches
Material Aluminum

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. 

Shipping & Returns

Our products ship through a privately owned climate-controlled warehouse in San Diego, California.

We offer a variety of shipping methods from budget-friendly to price-doesn’t-matter. You can compare estimated costs and transit times once you begin the checkout process and enter your shipping address. Carrier options may vary based on your destination.

We strive to pack and ship all items within 24 hours of each order (Monday through Friday). However, we are a small team so during peak holiday season we kindly ask that you allow 3-5 days for your items to be sent on their way. Every box shipped from Art of Play is expertly packed by actual human beings (you can see their names written on your package slip). Everyone in our warehouse is paid a fair wage and treated with respect.
