Rust

On the way to the Snæfellsnes peninsula, a little detour on a farm with a special spring that’s extremely rich in calcium, iron and all sorts of minerals. German scientists came and tested it in the 1750s. If a human had dug that hole, it’d be called “mine drainage” or something. They let us drink a bit of it, but it just tastes like fizzy iron, didn’t feel any healthier or anything.
