A metal object C (Faraday used a brass ball suspended by a nonconductive silk thread, [1] but modern experiments often use a small metal ball or disk mounted on an insulating handle [4]) is charged with electricity using an electrostatic machine and lowered into the container A without touching it. As it is lowered the charge detector's reading ...
Benjamin Franklin Drawing Electricity from the Sky, an artistic rendition of Franklin's kite experiment painted by Benjamin West, c. 1816 The BEP engraved the vignette Franklin and Electricity (c. 1860) which was used on the $10 National Bank Note from the 1860s to 1890s.
Lord Kelvin used this foundation of accumulated knowledge to, in 1859, create an apparatus involving the interaction of a stream of water with the Earth's static electric field to cause charge separation and subsequent measurement of charge to make atmospheric electricity measurements.

Many science museums, such as the American Museum of Science and Energy, have small-scale Van de Graaff generators on display, and exploit their static-producing qualities to create "lightning" or make people's hair stand up. Van de Graaff generators are also used in schools and science shows.
In 1745, Peter Collinson, a businessman from London who corresponded with American and European scientists, donated a German "glass tube" [4] along with instructions how to make static electricity, to Franklin's Library Company of Philadelphia. [5] Collinson was the library's London agent and provided the latest technology news from Europe.
Children interacting with the Winky Dink and You program. The central gimmick of the show, praised by Microsoft co-founder Bill Gates as "the first interactive TV show", [3] was the use of a "magic drawing screen" — a piece of transparent vinyl plastic that stuck to the television screen by means of static electricity.
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge . The word "static" is used to differentiate it from current electricity , where an electric charge flows through an electrical conductor .
