my second mini cannon *improved*

Unread postAuthor: spudthug » Sun Mar 04, 2007 6:08 pm

well here is my second mini cannon...this idea i got from the other highliter cannon but slightly improved.....

specs...-->

1. a highly technicaified marker chamber
2. a maroon pen from a local store
3. a roll of decrative and electrical tape
4. two inch screws for spark
5. an ignitor from a long nosed lighter
6. a butane cartridge
7. a bottle of superglue....


ok this cannon is fuel injected and so you have no moving parts to unscrew or something...when i got this idea i was looking at propane injected combustion cannons....so i decided *wow* i can make a butane injected gun....and this one is so powerful that i decided i wasnt going to get hurt by shooting my self again....so i didnt...and it penatrates through a pretty thick cardboard box and sticks into the other side... well enjoy....

Kind of a dumb, salty-ish question, but seeing as I didn't find it in the wiki, I'll ask it.
How did you get all the inky stuff out of the highlighter tube? I've never figured out a good way to do it. I guess it only works well with some?
