Watching watermelons and sheets of plywood meet their demise at the hands of a twisted slingshot creation is entertaining. But Joerg Sprave's latest creation, a custom crossbow bolt that's been modified to deliver a lethal dose of poison, is a little disheartening since it was created for killing, not just smashin' stuff.

And it goes without saying but we'll say it anyways, do NOT try this at home. Or anywhere. It's all but guaranteed that this particular experiment in home-grow weaponry will get you in hot water with local water enforcement. And explaining it away as a handy way to inject some extra flavour into a frozen turkey isn't going to fool anyone. We miss the cuddly, zombie-slaying Joerg. Can that guy come back and build us a Hello Kitty catapult or something? [YouTube]
