I made a thingy majigy with unlimited smoke.
Most people just trap a missile or rocket in a box and are done. i made it so that this thing doesn't even move in the thing so it cant escape. and also it has no thrust. it is only 8 parts and you can use it how many times you want and it will just make thicker smoke, just try it out yourself! here
and also why not
this is a teaser for my entry for the kamikaze challenge. it's not done. i tried to make new auto turrets for this and then i acidentally discovered something and now you have infinite smoke
