A lighting conductor is a metal pole which is set into the ground , going up the side of a building to the roof. In a storm, the air is full of electricity --- charges of this electricity are what we call lightening . It is attracted to the points of objects – so the tip of the conductor attracts the lighting , taking it down to the earth, and the building is not struck. The lighting conductor was invented by the American Benjamin Franklin in 1752.
