So we went over into Michael's garage -- his dad had all kinds of stuff, and we put a pipe in the vice there, and screwed a cap on the end of the pipe, drilled a hole in the back of the pipe, took some of our firecrackers, pulled out the fuses, tied them together, put them in the back there, and -- down in that hole -- and then stuffed some of our gunpowder down that pipe and put three ball bearings on the top, in the garage.
