First title is “The story of toilet” Long ago, people didn’t even have house. They roamed the forest, hunting animals and squatting behind a tree. Some built a toilet in the yard, but it was only a hole in the ground. When the hole filled up, they simply covered it with mud and dug another.
The ancient Romans had a much better idea of public toilets. They simply asked a slave to bring in a silver pot and filled it there and then. In later times, people were more shy about there things. Lords and ladies preferred to go alone, using fancy.
By 1880, the toilet had really arrived. Since then, only the shapes and decorations have changed. Today, we take toilets for granted. But spend a day in the woods and you’ll soon learn how things were for our ancestors.
Second title is “Telephones” Alexander Graham Bell was a boy with a mission. When Bell grew up, he got a job teaching deaf people to speak. One day, he played a chord on a piano and heard the exact notes echo on a piano next door. He thought he could send speech from one place to another. In those days, 150 years ago, the quickest way to send messages over long distances was by telegraph. A message was tapped at one end of an electric wire. Today, million of people own mobiles. A phone with no wire would have really impressed Alexander Bell-especially one that can send pictures too.
