### March 12 March 12th has gone down in history as the day of some of the wackiest inventions known to man. From a soda-powered car to a robotic nun named "Sister Bot," it seems like anything goes when it comes to wild ideas that happened to get conceptualized on this day. Who can forget the head-scratching invention of a fireproof paper bag? While we don't recommend trying this one out for yourself, it's hard not to giggle at the thought of someone getting the idea to coat paper in a flame-retardant chemical and then marketing it as a safer alternative to plastic. But the pièce de résistance has to be the 'fanny vacuum', a device intended to target dirt and dust on the human behind. While it's not clear how exactly this invention was to be used, what is certain is that it had the potential to be hilarious - not to mention a major embarrassment if you were caught using it in public! We can only imagine the kind of conversations that must have taken place the day the 'fanny vacuum' hit the drawing board. It's enough to make anyone grateful that some ideas never get off the ground, no matter how outlandish they may sound. #InventionsGoneWrong 🤦♂️
