To make a cap bomb, you will need a nail or a knife, some bottle caps, some tape, matches or a lighter, and a bottle rocket engine or piccolo pete. Make a hole in the center of one cap, add powder from the piccolo pete, and connect the fuse through the hole in the cap. Connect the two caps together and tape together. Light the fuse and watch it blow. If you follow the steps in this video you will learn how to make your own fireworks at home.
