alright, about a month ago, i came up with an idea, i thought it was brilliant...

the idea was to make a potato cannon with a twist: i was making it out of a pen, and i was ensuring that no part of the pen was damaged (complete portability, it would still be a working pen, no cop would think of thinking it was a deadly weapon).....on my first attempt, around a month ago, i accidentally broke the pen in half (it was a piece of shit)...today i found another pen which i thought would withstand the abuse i would have to do to it....and it came apart, and the barrel of it had a smaller part at the end to ensure the flame doesnt just go around the projectile...it was perfect...so i started to cut a touch hole in it (the only thing i would need would be a touch hole, all the other holes, and the cap were already there...hence the perfection).....so i cut the touch hole, (i didnt actually expect the touch hole to work right, thought i would accidentally cut too big of a hole...aparently i didnt...)....now i just needed a projectile...i thought one of the little airsoft gun bullets would be a great starter, so i got one of them.....

Of course, last month my brother was here, and he uses axe deodorant, i was going to use that as a fuel for it...now he is at some diagnosis center to figure out what meds he needs, and he took his axe with him...i dont have any fuckin fuel to test it with!!!!!!! i tried hairspray, but it wouldnt vaporize...(non arosol, no pressure in the can, comes out as a liquid)

so my brilliant idea (atleast in my eyes) which is essentially a zip gun but less dangerous, and reusable will have to wait until i get some sort of propellant...damn it!!!! .....or maybe i should use lighter fluid from my lighter...i think i might do that....

whell, i almost lit the pen on fire....(if i hadnt noticed that it was burning, i wouldnt have a pen anymore....)....so lighter fluid wont work....

its going to be difficult to get an oxygen fuel ratio in such a small area try alcohol. Isopprpyl might work, nail polish remover should work. use an eye dropper to administer a little less than a drop let it sit for about ten seconds.

you could use zippo lighter fuel

thats good advice...i never would have thought to use rubbing alcohol....i think we actually have that....i shall attempt this when my parents are at work tommorow....(or when they go to sleep....)

use butane
u can probably use
the nossle to spray in thru the touch
hole

massigy
if its so briliant
post a new thread

i think i saw a design for a pen potoato cannon online, but i cant recall where....possibly rotteneggs.com

hell yeah i think its brilliant...portable, concealable weapon which could easily be taken on a plane.......(no, i dont intend to use it on a plane...but you never know what you might need...)

perhaps i will look for this design...it could help me get ideas on how to improve it....


alright...i made an improval on my design..i found a pen with a larger barrel, and i am now using that so that i can fire larger projectiles more accurately......of course the pen i found is a click pen thingy, so i now require an external fuel tank, but this is good in a way cuz i can use a larger fuel tank if need be....

im thinking i could use a film cannister with a hole in the lid.....right now i am using the cap from another pen, but i still cant find any fuel....(we dont even have any damn rubbing alcohol, and my lighter is a piece of shit...)

ya idk if u wanna put the pen through an xray unless it has all of the original parts in it until u use it

Why don't you just buy some friggin' axe? One can goes for about 4 bucks I think, but if your using small amounts(which I can't imagine why you'd need large ones) it should go a looong way.
