A rubberband ball is fun to make and an amazing stress reliever. What's great is that you can put it together when you have the spare time, or you can attack this project all at once. Not only will you be able to throw it and bounce it, but this is one project that's never completed, because you can just keep on adding more and more rubber bands! These can be a lot of fun in your spare time! Here's how to get started on your very own rubber band ball.
