paper and soda bottle rocket launcher
I have a couple of questions regarding this build:1- Does the 1/2" PVC pipe that goes inside the soda bottle (the one that sticks straight up) need to be glued in place when joining it to the launcher?2- When you installed the air compressor fitting, did you use any teflon tape or plastic glue? Did create threads in the drilled hole? Or did you just tighten it into the hole without doing anything?
