Benjamin Franklin wanted to improve houses when lightning would occur. So in 1749, Franklin invented a lightning rod that protects any structure from lightning. When lightning hits, the lightning rod brings the lightning safely to the ground causing not as much heat damage.Добавлено на ленту времени:
