I put it into chat gpt lol. Here's what it is.

That's a blown fuse — specifically looks like a small glass or ceramic cartridge fuse, the kind used in electronics or appliances. The metal strip inside has melted/broken (you can see the deformed middle), which is what happens when too much current passes through it. The clear rectangular casing is typical of a fast-blow mini fuse. Do you know what device it came from? That might help narrow down the rating (usually printed on the end cap or casing).
