Miscellany
In 1745 a German cleric by the name of Ewald Georg von Kleist tried to pass an electrical current into a bottle through a nail and was shocked for his efforts. From this accident came the Leyden jar, an electrical condenser that allows electricity to be stored. The following year the abbé Jean-Antoine Nollet discharged a Leyden jar in front of Louis XV, sending electrical current through 180 Royal Guards, who jumped at the sensation.
