How about a full-auto, homemade crossbow?
Last month, you may remember reading about Youtube user JoergSprave's unique, 8-shot revolver airbow prototype. But he's also been working on something else for quite a while, and it seems he has finally succeeded in making a working design.
Behold his full-auto crossbow creation!
This guy has a wild imagination! Just when I think I've seen it all from him, he comes out with something new. It's utterly fascinating to see the unique creations he comes up with.
The comparison to the inner workings of an airsoft gun is interesting, because when he shoots it, it actually sounds just like an electric airsoft gun cycling.
While it looks like the accuracy is all over the place, you can't deny it works. Super creativity here Joerg, what will you come up with next?
