I made something like this in HS out of coffee cans with the bottoms cut out in half moon shapes. Then I duct taped them all together and would put rubbing alcohol in the top, shake it up and let it evaporate, and ignite from a nail hole in the bottom can. I could launch Gatorade bottles filled with water about 100 yards. It blew up once and I never bothered to put it back together. Plus my mom was hysterical.
