AWBRL for short. Just the other day I was watching a mythbusters episode where they made water bottle rocket launchers for a myth. It looked like so much fun and I went ahead and bought an aquapod for $35. It was great until it ruptured under normal use and no modifications! After that, I went to my local hardware store and bought a bunch of PVC fittings and a few other things so I could make my own with better reliability. This Instructable is about how to make a reliable, high performance, water bottle rocket launcher for cheap!

Signing UpStep 1: Safety
Now here is the important part. The safety information.
This is a pressure vessel. Pressure is dangerous. This bottle rocket launcher will utilize pressures up to 60psi. If you want to, you can add a safety valve but it would be easier to regulate the pressure with the source of air pressure. In my case, my portable air compressor.
Make sure you use pressure rated PVC pipe. sch40 is recommended but I used another type rated to 260psi
As with any pressure vessel, be cautious around it at all times.
ALL components MUST be pressure rated.
BE SAFE!
Do not use pressures over 60psi. There is no need. No increased performance at all!

About the energy, I am not sure but think a joule is a lot of it. Maybe you can ask an enginner or physicist.
