Nessler conducted his first experiments on his wife, Katharina Laible. The first two attempts resulted in completely burning her hair off and some scalp burns, but the method was improved and his electric permanent wave machine was used in London in 1909 on the long hair of the time.
To do this, Nessler first divided Laible's hair into three plaits, tying each close to her scalp, moistening the hair with a secret mixture, and winding the hair into spirals around metal rods that projected from the head like horns. With self-constructed, electrically heated tongs, similar to a waffle iron, he heated the plait-covered rods ...
German inventions and discoveries are ideas, objects, processes or techniques invented, innovated or discovered, partially or entirely, by Germans.Often, things discovered for the first time are also called inventions and in many cases, there is no clear line between the two.
The first half of the 700-page book is a history of the study of electricity. It is parted into ten periods, starting with early experiments "prior to those of Mr. Hawkesbee", finishing with variable experiments and discoveries made after Franklin's own experiments.
He left a detailed account of his research under the title of Experiments on the Origin of Electricity. [30] He discovered electrified bodies attracted light substances in a vacuum, indicating the electrical effect did not depend upon the air as a medium. He also added resin, and other substances, to the then known list of electrics. [11] [31 ...
1734 – Charles François de Cisternay DuFay (inspired by Gray's work to perform electrical experiments) dispels the effluvia theory by his paper in Volume 38 of the Philosophical Transactions of the Royal Society, describing his discovery of the distinction between two kinds of electricity: "resinous", produced by rubbing bodies such as amber ...
The water thread experiment is a phenomenon that occurs when two containers of deionized water, placed on an insulator, are connected by a thread, then a high-voltage positive electric charge is applied to one container, and a negative charge to the other. At a critical voltage, an unsupported water liquid bridge is formed between the ...
Armstrong Hydroelectric Machine. The Armstrong effect is the physical process by which static electricity is produced by the friction of a fluid. It was first discovered in 1840 when an electrical spark resulted from water droplets being swept out by escaping steam from a boiler.
