Product Idea |



This GBC (Great Ball Contraption) Module uses a new concept of a rotating square to lift the balls. This project uses several gears to achieve the movement of the square. It is easy to build and includes several Power Functions motors.

This would be a good set for kids and adults alike. It uses several different mechanics to move the balls in unlikely ways. It works well on a coffee table or desk. The purpose of this set would be to entertain, teach, and for lots of fun!
