late post i know but i got the spud gun to work.......kind of.
i realised that you have to have a piece of grounded metal next to the ignitor to make a big enough spark. so i cemented one in and then tried a tiny bit of deodreant....didnt work,,, so my entirely respnsible father took over and sprayed it in there for a good 5 seconds, gave me the cannon, i press the ignitor......now my right ear doesn't work, my dad has a massive bruise on his thigh from where the cap hit him, and the potato...is nowhere to be seen
SUCCESS
