You can start with any small object, such as a marble or golf ball. A "true" rubber band ball, however, includes no other materials. Here's how to get it started:  Select a short, thick rubber band, such as a band used to secure vegetables. Fold this rubber band in half, then in half again, then a third time if possible. Do not twist it; you should end up with a flat "stack" of rubber. While pinching the thick band flat, wrap a thinner rubber band around it. Twist the slack of the thinner band and wrap it over the thick one in the other direction. Continue to twist and wrap until there is no more slack in the thin band.
