Though PVC creates shards, and ABS only ruptures (and does not explode), It has been thoroughly researched by people at the the SpudTech forums (now closed) and now the people at Spudfiles, and Sch 40 and Sch 80 PVC are a tried and tested way to create Pneumatic spudguns.

Duct tape tears easily and in our tests it was unable to stop an exploding PVC tank (we went to twice the rated maximum pressure, and slammed the tank with a remote activated 10lbs sledgehammer). In fact the shards we so quick when they exited through the duct tape that they also went through the plywood box the canon was in.


in a second test the gun was wrapped in an old pair of heavy duty Jeans. (the leg part), and when it exploded the jeans held the shrapnel.



At any case pneumatic spudguns are VERY DANGEROUS!
they can be fun but they should be treated even more carefully than a real gun, because a gun can only fire in a single direction, a spudgun might explode if handled the wrong way!!!

be careful!!!!!!
