its just 4 basic cannons put together.


the problem with it is that the first shot is great, the second shot is ok, the third sucks and the fourth barly leaves the barrel. this is because by the time to shoot the fourth, it has already settled and the mix is no good. it nonetheless looks cool.

i think it would be great as a pneumatic, but not as a combustion.

"physics, gravity, and law enforcement are the only things that prevent me from operating at my full potential" - not sure, but i like the quote

you know you are not an engineer if you have to remind yourself "left loosy righty tighty"

hahaha. my next pneumatic should be a whole battery of short-barreled marble cannons, where the camber of one is the pilot of the other, so basically they all just go off in series.........

lol. thats pretty cool. not gonna lie..................
