Moving Forward...

Okay, so we're going with the Nerf gun idea. We're hoping to modify the air chamber to have a dynamic air valve. Basically, we're going to need a MASSIVE spring, and some mechanism of moving the valve. Two ideas that have been floated (and subsequently shot down) are a screwlike air chamber (impossible due to an internal plunger) or a variable-speed plunger (jury's still out on that, but we're going to need to replace the spring somehow). If those fail, Alex and Trevor will be spending a few hours of in-depth analysis figuring out how to make this happen. The goal is, in the end, to have the overall air pressure (and hence, velocity) changeable with a simple potentiometer.
