Main Question or Discussion Point
Hello, I'm working on a 4 stage 14kj railgun and want to make a nice display for some of the people that have helped me. Anyways, I'm looking for a way to turn my 1/2"x1/2"x1/2" aluminum projectile into a tracer. It will be under some serious acceleration jerks in excess of 16,000g's and will have several tens of thousands of amps traveling though it. It will most likely get quite hot and be capable of igniting most materials. I was considering just using some magnesium, but was going to check if there was some other less "fire starting likely" reactions that can illuminate a projectile going 900m/s.
