A key was attached to the string and connected to a Leyden jar, which Franklin assumed would accumulate electricity from the lightning. According to the legend, Franklin kept the string of the kite dry at his end to insulate him while the rest of the string was allowed to get wet in the rain to provide conductivity. The increased height allowed him to stay on the ground and the kite was less likely to electrocute him. Franklin himself is said to have conducted the experiment in June 1752, supposedly on the top of the spire on Christ Church in Philadelphia.įranklin realized the dangers of using conductive rods and instead used a kite. An attempt to replicate the experiment killed Georg Wilhelm Richmann in Saint Petersburg in August 1753, thought to be the victim of ball lightning. Such an experiment was carried out in May 1752 at Marly-la-Ville in northern France by Thomas-François Dalibard. In 1752, Franklin proposed an experiment with conductive rods to attract lightning to a Leyden jar, an early form of capacitor. “The experiment’s purpose was to uncover then unknown facts about the nature of lightning and electricity. ![]() The place of Franklin’s grave is also the location where he is purported to have conducted the kite experiment - Christ Church in Philadelphia, PA. His inventions included everything from bifocals and swim fins to electricity.
