What can you make with a handful of washers, a packet of screws, a length of chain, and a rudimentary understanding of welding? That's right, a medieval flail. This traditional weapon, made from items that most of us have in our garage or workshop, is simple to make, easy to use, and an effective way to protect yourself from zombies. In a recent video, YouTubers Evan and Katelyn demonstrate how to construct a zombie apocalypse flail using supplies from the hardware store. Please don't try this at home.
