Faraday's ice pail experiment is a simple electrostatics experiment performed in 1843 by British scientist Michael Faraday [1] [2] that demonstrates the effect of electrostatic induction on a conducting container. For a container, Faraday used a metal pail made to hold ice, which gave the experiment its name. [3]
The first electroscope was a pivoted needle (called the versorium), invented by British physician William Gilbert around 1600. [1] [2] The pith-ball electroscope and the gold-leaf electroscope are two classical types of electroscope [2] that are still used in physics education to demonstrate the principles of electrostatics.
Thermally insulated bag with ice packs Example of a thermal bag Example of a thermal bag. A thermal bag is a type of thermally insulated shipping container in the form of a bag which can be carried, usually made of thermally insulating materials and sometimes a refrigerant gel. It is used to help maintain the temperature of its contents ...
This is part of the electrical induction process, and is an example of the related "Faraday's ice bucket". Also, the idea of bringing small amounts of charge into the center of a large metal object with a large net charge, as happens in Kelvin's water dropper, relies on the same physics as in the operation of a van de Graaff generator .
Electrostatic machines are typically used in science classrooms to safely demonstrate electrical forces and high voltage phenomena. The elevated potential differences achieved have been also used for a variety of practical applications, such as operating X-ray tubes, particle accelerators, spectroscopy, medical applications, sterilization of food, and nuclear physics experiments.

[1] Building a versorium is a suggested exercise in science classes in many elementary schools. [5] [6] One reason is that the operation of the versorium is simple to understand and the device is suitable for building by even young students, but can still be used to illustrate many important concepts in electricity. The versorium can easily be ...
The gold-leaf electroscope was one of the instruments used to indicate electric charge. [1] It is still used for science demonstrations but has been superseded in most applications by electronic measuring instruments. The instrument consists of two thin leaves of gold foil suspended from an electrode.
