just gonna try to make a small homemade cannon just for the fun of it so I've got some cans or all the same size got a bunch of them so I've cut the tops off them and I'm just going to use can opener and pop some holes in like this small well all of them except the bottom so this will be this will be the bottom no holes the new idea is to start stacking them one on top of the other like that and we will do that right now oh we do have to make one side hole not on the bottom not on the bottom but on the side we've got one hole like that so now I've got three cans with holes in the bottom and the tops off one with the bottom one and a hole cut right there gonna take some duct tape and stick them together second one so now you see we're starting to get a barrel but really a combustion chamber the last one is operable so it fit inside I just took a rag and a little bit of duct tape and a small tube cannonball it's really soft just to fit inside like that already okay so I'm gonna just take some gasoline or some in here let it go down or force them into this small hole I have here and I'm just going to switch it back and forth trying to get some air fuel to go through that whole thing okay that should be good take our little projectile that I made put it in there see what happens there you go homemade cannon
