  1. 9v Battery Spark generator

    Hey guys! I'm going to make a potato canon and need a spark generator to ignite the fumes. I was thinking about a 9v battery because of its power and size. What I want it to do is basically be able to make a spark over a gap every 2 or 3 minutes. I have no electrical experience so please be specific. I can solder though.
