In this project I will be making homemade F class rocket motors using supplies you could get from walmart. Warning you can really hurt yourself playing with fire and rocket fuel and I will not take any responsibility for any injury or death caused by these rockets. Also do us all a favor and don't do anything stupid with these rockets.
