Purpose

The main purpose of this blog is to have fun. But I also have a secondary goal of getting kids who Nerf interested in science, engineering, and math. I want to show people what science and math can do for them. I have often found that something is easier to learn when I understand what I can do with it, and I hope the examples I have here are illustrative.
