minus-squareCandelestine@lemmy.worldlinkfedilinkarrow-up0·1 year agoBecause the rust is very fluffy, while the iron is very dense. So a very small volume of iron can turn into a large volume of rust. The iron is disappearing though. Just slowly. You could tell if you weighed it with a sensitive scale.
