Faraday employed a 7 in. diameter by 10.5 in. tall pewter pail on a wooden stool,(B) [1] but modern demonstrations often use a hollow metal sphere with a hole in the top, [10] or a cylinder of metal screen, [9] [12] mounted on an insulating stand. Its outside surface is connected by a wire to a sensitive electric charge detector.

The Leyden jar was used to conduct many early experiments in electricity, and its discovery was of fundamental importance in the study of electrostatics. It was the first means of accumulating and preserving electric charge in large quantities that could be discharged at the experimenter's will, thus overcoming a significant limit to early ...
Gilbert cloud chamber, assembled An alternative view of kit contents. The lab contained a cloud chamber allowing the viewer to watch alpha particles traveling at 12,000 miles per second (19,000,000 m/s), a spinthariscope showing the results of radioactive disintegration on a fluorescent screen, and an electroscope measuring the radioactivity of different substances in the set.
In the video game Portal 2, the antagonist GLaDOS is embedded into a potato-battery-run computer for a significant part of the game. [27] In The Big Bang Theory Season 6 episode "The Proton Resurgence", Leonard and Sheldon's childhood hero Professor Proton (Bob Newhart) attempts to show the group a potato battery, which amazes Penny.
Between 1747 and 1750, Franklin sent many letters to his friend Collinson in London about his experiments with the electrostatic machine and the Leyden jar, including his observations and theories on the principles of electricity. [12] These letters were collected and published in 1751 in a book entitled Experiments and Observations on Electricity.
