mini spud launcher

this is a very basic design for launching a piece of potato from combustion. the expansion chamber and barrel both need to be printed .02 vertical so there are no leaks. also i did mine 100% fill so it won't explode this is very important. also for added measure if you intend to try it please wrap it using duct tape atleast several times around the total device barrel and chamber. this has not been tested i take no responsibility for any accidents. this is a model to simply demonstrate how it would work. i added the fins so it can stand itself up and it makes it look kool like an old ww2 air bomb or mortar lol. hope you enjoy as much as i do.
