World's smallest magazine cover. IBM scientist Armin Knoll viewing a computer display of the record-setting cover of National Geographic Kids. Scientists from the IBM Zurich Research Laboratory invented a nano-sized heatable silicon tip 100,000 times smaller than a sharpened pencil point. This was used to etch a polymer (plastic) surface, creating patterns and structures on a microscopic scale. The resulting magazine cover was 11x14 micrometres, small enough for 2000 of them to fit on a grain of salt. This was confirmed as an official Guinness World Record. Photographed on 15 April 2014.
