This video by Arbor Scientific’s CoolStuff and Joel Bryan of Ball State University substitutes salt water for the original toxic mercury to recreate Michael Faraday’s original motor with a 9-V battery, 2-L soda bottle, and some neodymium magnets. Analyzing this motor helps students illustrate and develop basic ideas in electricity and magnetism, and this is the motor that supposedly inspired the apocryphal Faraday response to a politician asking about the utility of the effect: “Someday you can tax it.” (http://www.snopes.com/quotes/faraday.asp)
