Franklin's experiment established a link between lightning and electricity. Another myth that has been dispelled is that Franklin's kite was not struck by lightning. Experts believe he would have been electrocuted if it had happened. Instead, the kite gathered up the storm's ambient electrical charge. When it came in contact with a metal object such as a key or a fork, an arc of electricity was transmitted through the key to the string, which then moved the sail. The wind caught the sail and drove the boat forward. In addition to being an important scientist, Benjamin Franklin was also known for his inventiveness and creativity. He designed several other devices including a thermoscope, which was very popular in its time, and a centrifugal pump, which is still in use today. Franklin's ideas helped establish America as a leading nation in science. He is considered the father of both electricity and fire protection systems. Another fact about Benjamin Franklin is that he proposed the idea of the American flag to show unity during times of conflict and division. He felt that a single star could be added to the existing stars on the flag to represent each state. The blue color of the sky and the white color of snow are references to Franklin's love for his country.
