ha ha yea, ghetto cannons usually don't look great. but they are always one of the best words ever...CHEAP!!! lol


(if you noticed the little blue spot behind the barrel in the chamber thats a smaller extended piece of copper that i put there to latter i can convert the cannon into a cheapy hybrid and be able to put on a tin foil burst disk)

uhh idk the barrel size i just kinda took some copper pipe off my dads workbench lol. i guess i will measure it later and post it.

oh yea i shot it a few hours ago and it works realy well lol but the barrel is a little long and the coke bottle will expand during fire then start imploding on itself while the marble leaves the barrel then pop back to normal.

they melt if you let the flame burn for a period of time in the bottle. mine melt was from my lighter getting to far from the neck of the bottle.

yes, i used a lighter to warm it then needle nose plyers (s.p.) to widen it, i had to do the same to the cap i used as well and it is still a tight fit.

Plastic bottles have this thing about collapsing if heated too much but I guess if the fuel isn't overdone it'll be fine.

Looks nice'n neat for the price :wink:

yea but on first fire it does it.. :? ...mabey by the time the ammo reaches new the end of the barrel it is sucking air out of the chamber? idk, id on't think it would do that much really.

I bet a juice jug might work better, on the other hand pop bottles are made for presure, maybe a 3 liter.
