More About fridges
Fridges were made a long time ago. Before fridges, people used ice to keep food cold. This was hard and not safe. Now, fridges are in most homes. They help us eat fresh food every day.
Fridges are very helpful in our lives. They keep our milk cold and our fruits fresh. We can make ice for drinks. This makes hot days much better!
In the future, fridges may use less power. They might be smart and help us shop for food. Fridges will keep getting better!
