swan2swan:abyssalcorvid:injuries-in-dust:Fun Fact, thats, more or less, something that wealthy people in China and Japan did, they were called “musical floorboards.” Designed to squeak when stood upon. A person could make noise all the way down a corridor. The residents and servants knew which floorboards made a sound and avoided them. But a burglar, or assassin didn’t. If you heard the creaking of floorboards, you knew danger was coming. Even better, despite what movies may show, a lot of the old west was founded by Chinese immigrants, so there could have been carpenters around who knew how to make the musical floorboards!They were also called Nightingale Floors, and looking up to make sure I had the right term, I found they were super clever! They were more than just ill-fit boards or whatever makes floors creak normally, they actually used little metal bars under the boards placed into small holes in the boards to cause the creak.The best things on the internet are when someone makes a joke and then Miss Frizzle rolls up for an educational adventure. -- source link
