thanks for the help guys and ill go check out a local camping store for lantern lighters

it has 2 wires and spark jumps from one wire to the other

im not sure of the gap thow i better messure that

if i have the wires to far apart the spark wont jump so i have them pritty close to eatch other

but yeah ill mesure it to make sure its around 4mm gap

hey all i just finished making my first spud gun and well im worried if it will have enough spark to ignite im using hairspray and im using a barbecue lighters spark and running wires into the tube

here are some pics let me know what you think
