Summary: I made a bowling ball with James Bruton where it will steer left and right depending on how you lean. People lean anyways when the bowl to try and influence the direction so we just capitalized on that. It operates on the same principles of a BB8 ball.

Thanks to Carlyle tools for giving my workbench tools a seriously needed upgrade!
