Mark Rober used to build autonomous spacecraft bound for other planets. Now, he's a YouTuber. So one day, when he finally got fed up with thieves stealing packages from his doorstep, he did more than just catch them. He built an elaborate device to screw with the thieves, and documented the whole process. Check out the video of the "trap" in action here, and be sure watch Sean Hodgin's video on making the trap. I got upset that my package was stolen so I made a glitter bomb revenge package.
