Here's a fun fact: did you know that gas chambers were sometimes used for multiple executions at once? Yep, it's true - they'd cram a bunch of prisoners into the chamber and, well, you can guess what happened next. And, get this - some gas chambers even had special seating for witnesses, because who doesn't love a good show?
But, things get even . In some cases, the gas chamber was used for non-execution purposes - like, uh, fumigating prisoners' clothes. Yep, you read that right - they'd use the gas chamber to delouse people's clothes, because lice were a real problem back then.
