This tutorial is for everyone sitting in an office, most likely reading this post during their lunch hour or afternoon cup of coffee. Take a look around you. What you see are an endless stream of supplies that Jörg Sprave will show you how to turn into DIY weapons.
Sprave writes on his YouTube site that Businessweek challenged him to make weapons out of office supplies for their "how to" series. Making good on the challenge, Sprave -- who is well-known as the creator of "The Slinshot Channel" -- found there are actually a lot of "heavy, sharp things around" the office environment.
Main materials include paper, pencils, scissors, metal fasteners, rubber bands, hole punches and USB cables. Oh, and don't forget the Scotch tape. With them, he creates a pencil shooter (a sharp pencil is a must), a flail, "deadly" pick axe, and, of course, a signature slingshot.
See how it's all done for yourself:
Sprave goes as far as calling the office a "paradise for the eager makeshift weapons maker!"
