MIT Student creates his own grappling-hook gun

Grappling hook guns. From Batman to Rorschach from Watchmen, everybody wants them, but nobody really makes them. Unless there is some sort of spy company that actually makes them. Sort of like Q did for James Bond. An MIT mechanical engineering student has essentially given the world what it wants as he has created a full-functioning grappling hook gun. You can see a video of it after the jump, and it is made with some ordinary parts like a chemical fire extinguisher, copper pipe, hose clamps, blowgun, a 20 ounce CO2 canister, and it is mounted on NERF N-Strike Raider Rapid Fire CS 35. As you might have guessed, this is an Instructables project, by a user named “crreed”. He certainly has me wanting to build one of these bad boys, but I won’t be shooting pictures of Osama bin Laden. No way. I would be in a big city, atop a tall building, and then I would aim for a fire escape or something secure. Once I was was sure the hook was going to hold my weight, I would swing like Batman. Yeah, right, like I really would do that. Still, you have to wonder if it is legal to own a grappling hook gun. I mean, you could do some serious damage if you hit someone in the chest, like in Watchmen. I can’t remember if that happened in the movie, but I remember it from the comic book. Honestly, I think it is comic books that made me want to try swinging from buildings with a grappling-hook gun.
