More About fridge
Long ago, people used ice to keep food cold. They had a box with ice in it. Then, the fridge was made. It is much better than the icebox.
Today, we use fridges every day. They help us keep food fresh at home. We can enjoy cold drinks and snacks.
In the future, fridges may be even smarter. They might help us pick healthy food. That would be cool!
