Ben Franklin Kite and Key Experiment

Benjamin Franklin's lightning experiment. Artwork of Benjamin Franklin (1706-1790) and his 21-year-old son William, performing their famous lightning experiment of 1752. They flew a kite in a thunderstorm. A metal wire on the kite attracted a lightning strike and electricity flowed down the string to a key, charging a Leyden jar (capacitor). This experiment proved that lightning was an electrical phenomenon, and supported Franklin's invention of lightning rods. Some scientists died repeating the experiment, and the Franklins were lucky they were not killed themselves.
