I lesson I learned many moons ago, no matter how much fun it sounds like, do not just put a little propane in and shoot them at each other. The ER doc had a hard time believing my broken ribs were from falling off a boardwak, and that was after the potato had hit the top of a sand dune.
Firearms safety, anyone?

That's not happening. I had a friend who made an improvised flash bong with some steel pipe. He was damn lucky not to kill himself or anyone else.
I heard AquaNet has the most 'propellent' of all the hairsprays.

Back when soda/beer cans were tin, we used to cut the top and bottom off of several cans and tape them to make a tube leaving the tip and bottom on the bottom can. Poke several hole in the top of the bottom can before taping it to the tube and a couple holes in the bottom can. Fill the bottom can about half full of lighter fluid and slide a tennis ball into the tube. Aim, stand off to the side and put a lighter to a hole in the bottom can and it will go off like a cannon. We used to shoot them across to another barracks building when I was a youngster in the army. We called them tennis ball mortars. Sometimes the tennis ball would get lighter fluid on it and come out on fire.
We did this in university. Then, being a group of less than brilliant engineers, we decided to improve it by using lighter fluid and oxygen from the oxy-acetylene rig in the lab. We at least had the sense to fire it with a fuse and hide behind the drafting tables. There were lots of shrapnel bits in the suspended ceiling and we scared the crap out of the Green Hornets parking enforcers in the parking lot.They had been out of range before we added the oxygen.
Ultimate would be to use oxygen and acetylene. Saw that done in welding class. 4' schedule 80 steel pipe. (That's heavy!) 1/4" hole at the base, pipe was the diameter of a golf ball. Little squirt of both gasses, then lit it off with the torch. Golf balls are never seen again, and he said he had split several of the pipes. Don't try this at home. Zombies would have no chance at all.
not to be the debbie downer, but technically the hair spray/propane/oxy-acetylene powered spud guns are illegal, since they use an explosive to propel the projectile. there are plans that you can find to make an air compressor powered one that goes just as far.
I want in on this. I'm just trying to decide on my ammo in order to pick a barrel. Golf balls?
You Tube has a dozen golf ball cannons, personally I'm attracted to the bowling ball cannons.
I met a guy in a parts store two summers ago, the white part of his eye was beet red, his cheek all burned and slightly bruised. Seems the ignitor came out of his potato gun, blasted him in the face.
Be careful out there.
I fire from hip level with the clean out plug pointing backwards away from me.
My buddy's dad shot yams with his.

My last company used to water jet parts for this guys cannons: http://www.blackpowder-cannons.com/
They are a lot cheaper than you would think for basic no frills mortars. If you get bolt together ones, most of them can be sent through USPS flat rate boxes, so shipping isn't even as bad as you think.
Also attach an old sock to a length of rope and the rope to the gun. Now you can stuff the sock down the barrel and shot "loose" items like rocks, BBs, paintballs in massive quantities.
