PVC wouldn't be safe, and metal is heavy. So, maybe it could just be a stationary type affair.
Ice or hard packed snow could be a good projectile, but it would suck being hit with it. Although maybe a combustion with a large diameter barrel, or some sort of device to restrict the flow of gases could help reduce the pressure, and maybe allow the use of a softer projectile so it wouldn't get torn apart.
I'm weird, I know it, you don't need to tell me.
