Benjamin Franklin was an american scientist and inventor in the eighteen th century. He was always very curious about the world and is often helped him solve different problems. Back in those days, lightning often hit buildings during thunder storms. There were many terrible fires, and the west fires could burn whole towns to the ground. Franklin wanted to prevent such things. He believed that lightning was actually electricity. So he decided to fly a kite during a thunder storm to see if he was right. He made a silk kite with a metal wire on top. Then he attached a hemp string to the bottom part of the kite. When the hemp p string got wet, IT could conduct electricity. Frankton also attached a metal key and a silk string to the hemp string. One day in june seventeen and fifty two, a thunderstorm was coming in. So Franklin and his son went out with the kite. They flew IT high in the sky. Then they walked inside a farm building. However, they left the door open so the kite could continue flying that way. They kept the silk string dry. This was very important. They didn't want to get hit by lightning. Franklin was pulling on the string anxiously. When lightning flashed near the kite, he put his hand close to the key and felt an electric shock. I've been shocked. Success, success. He shouted to his son, Franklins experiment was very dangerous. No one should ever try IT today. In fact, Franklin was lucky that the kite wasn't hit by lightning. IT would have killed him. However, he did lead to one of Franklin inventions, the lightning road in Franklin day. Lightning rod saved buildings from being destroyed by fire. They continue to protect buildings today.
