What Are Those Balls on Power Lines For?
When I was little, I remember driving in the car with my grandfather near Frog Island in Stillwater. Over the Hudson River near the railroad bridge are power lines that stretch across to the other side of the river. Every few feet there are giant red balls on the power lines. When I asked my grandfather what those balls were for he said that when the water rises from the river and reaches the power lines, they are able to float. I was young so I believed him.
