ASTROJAX - THE FREE-DIMENSIONAL ORBITER

What are Astrojax?

It is essentially 3 weighted foam balls attached by a piece of string with the middle ball freely moving. Although it sounds quite simple, the construction of Astrojax is very sophisticated. Incorrect spellings include Astro-Jax, Astrojacks, and Asto-Jacks.

Each ball has a high-density precision-machined metal weight to provide maximum performance and smooth action while playing. The fast spinning motion of the balls is based on the physical principles of rotational dynamics.

Astrojax was invented by the American physicist Larry Shaw.
While still at graduate school Shaw discovered the basic principle of Astrojax while playing with hex nuts and dental floss in a physics lab.
Intrigued by the complex patterns this simple arrangement created, he started to develop the idea. What first looked quite simple was actually very hard to solve mathematically. It took almost two years and hundreds of prototypes before Shaw decided on a model and had the principle patented.

Astrojax is an entirely new breed of toy, a revolutionary concept with possibilities we are only just starting to understand. Every day Astrojax players around the world are discovering new tricks and exciting moves no one thought were possible. And word is spreading fast that Astrojax is what the real thrill seekers are now playing - a game all about action, rhythm and your own personal style.
