disclaimer:
ok since this spud gun is really held together by tape, it can explode so wear safety gloves, earplugs, and safety glasses.
i dont take any responsibility if you do get harmed by this gun, i also do not take responsibility if u harm other people or things.
sorry for the bad picture quality.
and for those who think i copyed it off youtube. i didnt because i made this before i saw the vid on youtube.

...i thought it was pretty cool.
you inspired me to make another instructable :D
solenoidsare basicaly like motors, but instead of going spining when electricity passes through them, they push or pull the shaft, now correct me if im wrong, but doesnt a camera cap spark generatre quite a bit of heat? a bbq peizo does not do this to the air, but if the spark travels through a fuel, it will heat the fuel, a cap spark is much hotter and powerful, it will definitely ignite the fuel in your gun, even if theres too much or too little, but youll know that when the shot is tiny.
hope i helped
Could I use alcohol for the fuel? Maybe I should just go for the pneumatic spud gun, but I still have no pump :( So many problems...
alcohol will dissolve the pvc , so will hairspray, go safe , use butane, or propane if you can. but a mixture of the two, such as found in hair spray is best.
if using hair spray please use an anti liquid pray filter, it only allows the gas out, but traps most of the dangerous liquids that melt your potato gun
this happend with a friend, he wasnt hurt, but he realised what could have happend if he was.
anywho, to prevent this just coat the inside with wax, or if your superserious on PERMANANTLY using your potato lucher, using alchohol or gasolene as a fuel, vapourise plastic and have it coat the inside.
to do thsis is quite simple, for wax, just put a hell of a lot of cotton in a wax candle that has melted, light it up so you get a very big flame, then place some kind of weak oxidizer on it, like powderd potasium nitrate (just to keep it smoking after its blown out), then blow it out and instantly place it inside your sealed barrel, at this time the candle (which must be in a metal holder of some sorts), should be rather hot, it will produce alot of smaoke, which is wax vapur, it will collect of the sides of you spud gun, hooray , longer lasting spud gun.
now i know wax dissolves in gasolene, but when like thart cannot combust, under the exploding conditions inside the spud gun.
basically youll know when your spud gun would normally be melting inside when the wax becomes runny or gooey. yes, this will make it last for a long time, and is recomended for those complex multi-part potato launchers that are made in countries without the riddiculously large reducers avalible in america, so basiclly, complex ones, this is what its for, also sugar works ok too, but its hard to tell if its water or fual making it gooey, when in humid conditions.
