The original trigger for this high power PVC air cannon used a simple ball valve for the trigger. [Ben] didn't like this solution it was hard to open and somewhat unergonomic. The ball valve trigger has since been replaced with a valve from a sprinkler system, giving this high power PVC air cannon a fancy brass trigger. It looks awesome, and can kill a watermelon from twenty yards.
