Bar installs Faraday cage to block phone signals
Steve Tyler, owner of British cocktail bar 'Gin Tub', has installed a 'Faraday cage' in his bar's walls to block mobile phone signals, hoping that customers will be encouraged to talk to each other. A Faraday cage is an enclosure made of a conductive material and used to block electric fields, an effect discovered by scientist Michael Faraday in 1836.
