A few days before this science experiment the teachers put a few hard boiled eggs in a container full of cola. We asked the children to make predictions about what would happen to the eggs after they sat in the cola for a few days. A few days later we opened the container to find out the eggs were stained brown from the cola. We explained to the children that this is similar to the effect cola has on their teeth. We gave them tooth brushes and let them practice washing away the stains from the eggs.
