Halloween’s as good a time as any to solidify your zombie protocol. And there’s no more time-honoured zombie trope than thinning a crush of zombies around a building from a rooftop. But a regular slingshot doesn’t have quite the stopping power required. The answer? A giant zombie-obliterating rooftop slingshot.

Your average slingshot, even one made by bean shooter expert Joerg Sprave, doesn’t really have the stopping power to deal with a mass of undead at your gates. So Sprave assembled a humongous, angling, roof-mounted, undeath-dealing slingshot that’s powerful enough to blow an exit funnel into a dense piece of wood. Yeah, I think that’ll do the trick.
