Joerg Sprave's latest slingshot takes a very simple concept and makes it wonderfully fun and dangerous: What do you throw that you'd rather fire out of a high-powered homemade slingshot? Throwing knives!

But there's so much potential for more. What else? Baseballs, bowling balls, molotov cocktails, lawn darts, horseshoes, boomerangs, acid, dem 'bows, anvils, Wolverine, cell phones, cars, husbands, bird houses. And like, other stuff too. Glad to see Joerg's back to his roots lately, between this piece of wonderful and the last month's steak knife lawsuit magnet. [YouTube]
