me and a buddy where talking and would it be possible to build a polish cannon out of 55 gallon drums and shoot a exersice ball out of it or would the 55 gallon drums be way too thin

Stop being a dorkweasel and get your head out of your bum.
Think son, think. If your not capable of conceiving the relative forces for that cannon, then you 'ought not be buildin' her.

Wow, still a fail... Dude, I recommend starting off with something small like a regular 'ol spray and pray. 1 foot x 3" chamber and a 3 foot by 2" barrel.

Whenever I read "polish cannon" I cannot but think of this unfortunate
AC-119 Stinger nose art...

I say go for it. I see nothing at all wrong with using a steel barrel to launch excercise balls.

I have (unfortunately) seen sealed steel drums rupture violently due only to volatile solvents inside expanding as a result of solar heat, bowing out and tearing at the seams. They're tough, but internal surfaces are large and there's a lot of force imposed on them even with low pressure.
Not saying this won't work, but caution should be exercised

Yeah thats a good point. Remote detonation highly suggested. No hand helds

That would certainly be amusing, to distant onlookers at least

You could wrap the tanks in fiberglass. and it would be amusing to see someone hand hold the cannon.

If you do make one, video would be awesome.
