have you always wanted one of those cool bottle rocket launchers but couldnt afford one? well that happened to me, so I took action. I WILL SHOW YOU HOW TO MAKE A BOTTLE ROCKET LAUNCHER FOR UNDER 10 BUCKS! I think... I have not tested this yet so I'm not sure if it works. I am not responsible for the stupid things you decide to do with this. You will need a mask for protection. Also gloves are reccomended, but not required.
Step 1: Get a Pvc pipe, tape and a toilet paper roll
