The ingenuity of humanity never ceases to amaze me. As such, I am mesmerized by the bike-chain & electric-drill powered magazine-fed pencil machine gun (or perhaps just the voice) of YouTube user Joerg Sprave and The Slingshot Channel.
Just in case you have not seen him before (and have time to spend hooked to YouTube), he shoots crazy objects like pencils, plungers, knifes, machetes and spears with a variety of home-grown and personally designed rubber-powered shooters.
Just for the Holidays, he shoots an entire-freaking Christmas tree with a slingshot.
