Light Bulb Coloring Page

Thomas Edison and his team at Menlo Park, New Jersey, tested thousands of materials to find a thin thread that would glow inside a glass bulb without burning up. In 1879 one of their bulbs glowed for about 13 hours, and the next year a thread made from bamboo lasted more than 1,000 hours. Joseph Swan in England was working on a light bulb at the same time.

Electric light was safer than candles and gas lamps, which could start fires, and it meant people could work and read after dark. Moths still can't resist a bright bulb. Scientists think they steer by the Moon, and a nearby light fools them into flying in circles around it.
