 Well, and that's what creates rust, correct? That's right. It's a combination of things. I say this all the time. You ever go down and you'll see television or movies where they've got shipwrecks down at the bottom of the ocean, and if they're far enough down, they're not rusted because there's no oxygen in the water, and it'll sit under the water. So it's not necessarily water that makes something rust. It's got to be water, oxygen. It's got to be the right combination of things.
