How To Make A High Power Air Cannon - 2

In this video I build a high power air cannon using a PVC piston from my previous video (seen here): https://youtu.be/BCZGWvieJ7I

In case you're wondering how this cannon valve operates, I demonstrate the internal function at the 5:35 mark in this video.
The sprinkler valve I use at the end of the video was modified as shown here: https://youtu.be/ymfrrX5kIvM?t=1m16s
