i hope that posted... ill post the small righting here


slightly edited for more info/ alterd info---->
"P.P.B.C. (Propane Powered Blast Cannon) is, in my mind a grand idea,, its a type of canna that can never be moved or aimed ( untill someone creates a way.... ) it would be mostly for show.....
As you can see its very self explainatory,, the O's are valves, anything greyish purple is concrete, the seat is a seat, and the bage color is the inside....
it works with these steps..:
1. open valve neer chair an attach compressed Propane tank to it and pump till you s***l something ( you know its pressurizzed ) close valve ..
2. open top valve labeld 1 and drop a long burning substance in there thats self sufficiant, close valve 1,, and open the valve maked 2....... boom your ammo should be launched..."




if you like the picture thank you,,, it was made in paint :D

I think it's a good idea if you have the time on your hands, but setting concrete and such would be tedious, That being said Modifications could be made ;) nice design though

i know it would need to be re-modeled hahahhaa,, also i think i need to think of a way of preventing a "bad fire" where the cannon fires instead of the ammo


edit:
how to make ammo:
step1 place a balloon into the cannons launcher thing
step2 fill with cement/ something that solidafys
step 3. make sure balloon fills gap,,,,, then hold there till hard
step 4. your ready to fire :)

Its a nice idea, but the idea of it being a still cannon just keeps eating at me
