For all the iPhones, virtual reality headsets, deep space rocket engines and self-driving cars that are a part of our modern world, many a crazy contraption was invented along the way. It’s entirely possible the ideas presented below are not the weirdest inventions ever simply because the truly weird ones probably never got close to the light of day or their creators were somehow destroyed in the process. Still, these are some of the strangest fruits of human ingenuity we know.

1. MOUSETRAP PISTOL - this 1882 invention by James A. Williams of Texas, takes a very serious approach to mice infestations. The product never took off as people were wary of keeping .50-caliber-loaded revolvers patrolling their kitchen floors.
