In this video we make electric matches to safely detonate our experiments. You should aim for a 95-5% ratio of your propellent to nitrocellulose (pingpong balls). a pingpong ball weighs 2g, so use about 50g of powder. We used half that and it works great. The steel wool is sensitive enough to glow red hot through 100ft of wire with a battery.
