After having packages stolen off his porch and the police not being able to do anything about it even with security camera footage this guy spent six months designing a device to get his revenge! It looks like a normal package, but would track and record the reactions of people as the package sprayed them with glitter and simulated a fart smell! I don't know if they plan to mass manufacture and sell these, but the closest thing I could think of doing myself is packaging up some of my dog's poop in an old Amazon box. It wouldn't come with the satisfaction of seeing the thieves reaction, but it would make me feel better knowing I got some kind of revenge!
