Rust happens when metal meets water and oxygen. Imagine your metal object is like a hungry person who eats oxygen and drinks water, the result is a brown, flaky layer called rust. To stop it from happening, we can cover the metal or change what it’s eating.
Examples
- A bike left in the rain turns brown and flaky after a few weeks.
- An old nail on the ground looks rusty and weak compared to a new one.
- Your fridge’s hinge starts to look like it has skin peeling off.
