What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How does a fridge door stay sealed without a latch?

The Big Idea

Have you ever noticed that a fridge door closes tight without any latch or lock? The secret is a magnet hidden in the rubber seal around the edge. Let's find out how this clever seal keeps the cold air in!

A Magnet in the Rubber

Step one: a magnet in the rubber. The rubber seal around a fridge door has a flexible magnet inside it. It runs all the way around the edge of the door.

It Pulls the Door Shut

Step two: it pulls the door shut. The magnet pulls the door against the steel cabinet, so cold air stays in and warm air stays out. That keeps your food fresh and saves energy.

Safe and Easy

Step three: safe and easy. The pull is strong enough to keep the door closed, but weak enough that you can open it easily. It is also safe, because the door can be pushed open from the inside.

A Closer Look

Let's take a closer look! The seal is made of rubber. A flexible magnet runs inside it. The magnet pulls on the steel cabinet. So the cold stays inside.

Quick Facts

Quick facts! Older fridges used latches, but magnetic seals replaced them. The pull is strong enough to seal the door. It is weak enough that you can open it easily. And the door always opens from the inside.

Think Like a Scientist

Now, think like a scientist! Close a sheet of paper in the fridge door. Try to pull it out. Feel how the magnetic seal grips it. Then open the door and look for the strip.
