There are plenty of everyday products with bizarre origin stories, from Viagra's initial development as a treatment for heart disease to Play-Doh's first foray as a wallpaper cleaner. There are others, though, whose genesis came about under much more sordid circumstances.
To clue you in, we dug up 10 seemingly innocuous household items whose beginnings were much darker than you'd imagine. Spoiler: graham crackers will never taste the same.

Origin: A gas mask filter
Before you were using them to blow your nose and clean up after yourself, these iconic facial tissues were originally developed to function as disposable gas mask filters during World War I.

During World War I, the German chemist spent a good deal of time developing and weaponizing poison gas-- specifically chlorine--which led some declaring him a war criminal.

Origin: Nazi broadcast technology
While modern technology has sprinted far ahead of this unique recording method, found in everything from reel-to-reel recorders to cassette tapes, it was state-of-the-art back when the Nazis developed it to record and rebroadcast their radio addresses. It wasn't until the war ended that the Allies were able to bring the technology out of Germany and make it commercially viable.
