This video shows you, purely through demonstration, how to make a rubber band ball out of only rubber bands. It begins by showing how to create a small knot out of a few rubber bands, then wrap more rubber bands around it as one would with the small ball that is usually used as the core of a rubber band ball. The first few seconds are the most important, as forming the core of the ball out of rubber bands is the main trick to successfully creating the one hundred percent rubber band ball. Unfortunately, the video moves too fast to see what happens at the beginning. However, if you watch the beginning very closely, you too can create a rubber band ball out of only rubber bands.
