21. Crosse first started experimenting with electricity during his time in the sixth form, when he built a Leyden jar . 22. Franklin experimented not only with the electrostatic machine with the glass globe, but with the Leyden jar as well. 23. Franklin designed a " dissectible " Leyden jar " ( right ) ", which was widely used in demonstrations. 24. It can charge a Leyden jar to many thousands of volts and electrify small objects hung from silk threads. 25. Benjamin Franklin, for example, used a Leyden jar to store electricity from lightning in his famous kite experiment in 1752. 26. Each time the clappers touch a bell, charge is transferred between the inner and outer surfaces of the Leyden jar . 27. Braun's circuit afforded a much longer sustained oscillation because the energy encountered less losses swinging between coil and Leyden Jars . 28. Braun's circuit afforded a much longer sustained oscillation because the energy encountered less loss swinging between coil and Leyden Jars . 29. Dunkin constructed for himself an electrical machine, voltaic piles, and Leyden jars , and made models illustrative of the principles of mechanics. 30. The Leyden jar was the first means of storing an electric charge which then could be discharged at the experimenter's will.
