Faraday's ice pail experiment is a simple electrostatics experiment performed in 1843 by British scientist Michael Faraday 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.
 The experiment shows that an electric charge enclosed inside a conducting shell induces an equal charge on the shell, and that in an electrically conducting body, the charge resides entirely on the surface.
 It also demonstrates the principles behind electromagnetic shielding such as employed in the "Faraday cage".
 The ice pail experiment was the first precise "quantitative" experiment on electrostatic charge.
 It is still used today in lecture demonstrations and physics laboratory courses to teach the principles of electrostatics.
The oil drop experiment was performed by Robert A. Millikan and Harvey Fletcher in 1909 to measure the elementary electric charge (the charge of the electron).
Bisporella citrina, commonly known as yellow fairy cups or lemon discos, is a species of fungus in the family Helotiaceae.
 The fungus produces tiny yellow cups up to 3 mm in diameter, often without stalks, that fruit in groups or dense clusters on decaying deciduous wood that has lost its bark.
 The widely distributed species is found in North Africa, Asia, Europe, North America, and Central and South America.
 Found in late summer and autumn, the fungus is fairly common, but is easily overlooked owing to its small size.
 There are several similar species that can in most cases be distinguished by differences in color, morphology, or substrate.
 Microscopically, "B. citrina" can be distinguished from these lookalikes by its elliptical spores, which have a central partition, and an oil drop at each end.
Robert Andrews Millikan (March 22, 1868 – December 19, 1953) was an American experimental physicist honored with the Nobel Prize for Physics in 1923 for the measurement of the elementary electronic charge and for his work on the photoelectric effect.
Discos Qualiton was a record label, published by the extinct recording studio Fonema S.A.
 A garage experiment born in Rosario, Argentina in 1961, Qualiton would later become a major independent project influencing a generation of artists, writers, musicians, poets and filmmakers.
Alexander A. Kordyuk (born December 9, 1967) is a Ukrainian experimental physicist, known mainly for invention of the Method of frozen images and several experimental techniques based on magnetic levitation, and for contribution to the field of high temperature superconductivity.
Johann Christian Poggendorff (29 December 1796 – 24 January 1877), was a German physicist born in Hamburg.
 By far the greater and more important part of his work related to electricity and magnetism.
 Poggendorff is known for his electrostatic motor which is analogous to Wilhelm Holtz's electrostatic machine.
 In 1841 he described the use of the potentiometer for measurement of electrical potentials without current draw.
Clavulina is a genus of fungi in the family Clavulinaceae, in the Cantharelloid clade (order Cantharellales).
.
 Species are characterized by having extensively branched fruit bodies, white spore print, and bisterigmate basidia (often with secondary septation).
 Branches cylindrical or flattened, blunt, pointed or crested at apex.
 Hyphae with or without clamps.
 Basidia cylindrical to narrowly clavate, mostly with two sterigmata which are large and strongly incurved.
 Spores subspherical or broadly ellipsoid, smooth, thin-walled, each with one large oil drop or guttule.
 The genus contains approximately 45 species with a worldwide distribution, primarily in tropical regions.
 Species of "Clavulina" are mostly ectomycorrhizal.
 A recent study has identified Clavulina to the genera level as present on "Nothofagus menziesii" adventitious roots
The pitch drop experiment is a long-term experiment that measures the flow of a piece of pitch over many years.
 Pitch is the name for any of a number of highly viscous liquids that appear solid, most commonly bitumen.
 At room temperature, tar pitch flows at a very low rate, taking several years to form a single drop.
Electrostatic levitation is the process of using an electric field to levitate a charged object and counteract the effects of gravity.
 It was used, for instance, in Robert Millikan's oil drop experiment and is used to suspend the gyroscopes in Gravity Probe B during launch.
