Today I am going to show you how to make a bouncy ball in five minutes. I remember doing this during Science Class a million years ago and I thought it would. Make all kinds of bouncy balls react to sounds from your microphone. A great classroom noise monitor and management tool, and a fun way to visualize music. A bouncy ball, power ball or super ball is a small polybutadiene rubber bouncing ball which rebounds proportionally to the amount of force used when thrown at.
