Make sure to BE CREATIVE about what you shoot out of your fun new cannon! I like to use balls of foil, marshmallows, and even batteries! Make sure to BE SAFE, and HAVE FUN! ~(Disclaimer)~ I am not responsible for any injuries caused by this instructible. Do not attempt to build this unless you have supervision from an adult. This is a POWERFUL machine and shall not be used for aiming at another individual. They could be seriously injured!
