Extension cord

An extension cord is like a long tail that helps electricity travel further. You know how you have to sit close to the TV to watch cartoons sometimes? That's because the electricity that makes the TV work can only travel a certain distance before it gets weak. An extension cord helps the electricity travel further, so you can plug things in farther away from the wall. It's important to be careful with extension cords though, because if they get tangled or damaged, they can become dangerous. Always ask a grown-up for help when using an extension cord.
