Grappling Hook Launcher

MIT student Christian Reed built this pneumatic grappling hook launcher.

As surprising as it is, there really is no where on the internet where I found any decent instructions on how to make a grappling hook gun. Figuring it would not be that hard to make, I decided to design and make one myself.
