This was the same tank that was on our t-shirt shooter before I revamped it last summer. PVC is dangerous and should not be used for storing air pressure, and certainly not anything above what you are already trying! Please at least put duct tape or something around the tank. Make a wooden box or something to go around it when it explodes.

I am perfectly aware of the dangers of PVC pipe. I'm testing the cannon from behind a half inch glass door as I stated, doing the testing outside, and there is a large block of wood separating it from me. From the time the cannon has pressure in it to the time it's fired I am no where near the cannon. The valve and compressor are controlled remotely from my laptop and I don't feel like I'm in danger.
