Introduction: Nerf "Gun Smoke" Mod
A simple mod I came up with while messing with my old nerf gun. Really what it does, is when you fire a dart, a dart will be shot, but it will have a puff of "smoke" (dart pieces) fly out behind it, giving it the effect of gun smoke.
And really all you need to do is cut a dart in half, and then cut up the rest into rings.
Here's a vid that shows the effect and a better tutorial:
