Is it possible to make something that looks and sounds like a stun gun (makes sparks and zapping sounds) but can't actually cause harm (i.e. I'm not trying to make a weapon but something that looks like one). My idea is to make a cyberpunk jacket with, like, five or six pairs of studs down each arm and when I push a button the top studs spark, then the next ones down and so on in fast sequence. I could possibly use speakers to make the snapping sounds but I'd like actual bright sparks to happen between the pairs of studs - it doesn't need to fool a stun-gun officionado but I'd like it to look real to someone who last saw a stun gun in a YouTube video 12 months ago (for example). I'd probably just wear it to maker faires and bar fights.
