I'm not the best at relaying messages, so maybe I screwed something when remembering what Dad said. What I know about electronics is minimal, but not zero. I certainly didn't go to school for it. :D
Any way, maybe we just aren't getting the real thing that makes a Zapper work. Maybe the amount of voltage that gets into the body is not what kills the buggers, maybe it's all elecltromagnetic fields... I'm running out of electrons too!
