How to Make a Safe Bottle Launcher

Step-by-Step Guide

   Step 1: First you will need to have a bottle launcher that launches the rocket after a certain amount of pressure build up.

   You can make a sophisticated launcher from many of the other wikis on bottle rockets.
   
   The easiest way is to glue a source of air pressure to the PVC pipe such as a compressor or pump.
   
   Slide a two liter bottle over the PVC pipe an apply air pressure.
   
   After a certain amount of pressure the rocket will shoot off.
