Blows powder thru the front barrel, using a NOS solenoid, high pressure lines and a servo operated cam to trigger the micro-switch. Pressure tank is buried in the center section, and is constructed from two thermos bottle inner liners welded together. Holds 300 psi easily. Filled from a paint ball Co2 bottle.
I am currently using flour as powder, but need some suggestions for a dark colored substance. I've thought about black pepper...but that could lead to a sneezing problem.
Very cool. Sounds similar to the system on a crop duster a guy used to win Top Gun a year or so ago.
Not sure why you want a dark colored powder. The smoke trail from the real one is mostly white.
