Ah, cassette fluid - the unsung hero of vintage tech that's as intriguing as a ghost in a record player. Picture this: it's the gooey, oily concoction that seeps from a cassette tape after being dropped on a concrete floor, or worse, left in a humid bathroom. It's like nature's own, "Oh no!" spray can, but with more sappy lyrics and a lot less sunscreen.
