How Does a Clock Work Without Electricity?

A clock without electricity uses gears, springs, or weights to keep moving. Imagine a big toy car that keeps going because it has a rubber band, when you pull the rubber band back and let go, it makes the wheels spin. A mechanical clock is like that toy car: inside are tiny gears that turn one after another, keeping time without needing electricity.
