i wanna make a reusable self destruct tnt cannon

so, i saw Self destruct tnt cannons on yt, decided i wannna make 'em, it'd good, but i wonder, if theres a reusable self destruct tnt cannon, like. a cannon that has the destruction of a self destruct cannon, but it doesnt destroy itself, ik there are fence gate cannons which are also pretty good and get simaller outcomes, but i kinda want a reusable tnt cannon design, i dont even know if that's possible, if ya'll can make it, please show us how to, and ya'll can even make vids on how to and get loads of bread, so yea, that's an idea i came up in the shower, so that's it.
