It isn’t often that the world of Hackaday intersects with the world of crafting, which is perhaps a shame because many of the skills and techniques of the two have significant overlap.

Even Joke Torpedoes Are Pretty Hard To Get Right
https://hackaday.com/2019/09/14/even-joke-torpedoes-are-pretty-hard-to-get-right/
It’s rare that makers get involved in out-and-out munition production. It’s dangerous, and usually frowned upon by local authorities. That said, it can be fun to experiment around, and [Ivan] does just that, attempting to launch a 3D-printed torpedo from a kayak.
