Lets make It!
Step 1: Safety
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.
Do not use pressures over 60psi. There is no need. No increased performance at all!
