Rust actually sounds like a very interesting topic if you think about it a bit.
Fun fact, did you know that you are rusting, right now? Breathing is rusting, specifically it’s oxidisation of iron in your blood. It’s how your blood carries oxygen around your body.
Does that mean that if we took something rusty and put it in an environment without oxygen it would start to release oxygen from the rust?
There’s another factor involved to convince the iron to let go of the oxygen, so if we mimicked that as well, then yes. It’s just chemical reactions.
