The canary yellow sticky pads quickly become one of the best-selling office supply products in history and a ubiquitous staple in schools and offices around the world. No, Post-it Notes were not invented by the title characters in Romy and Michele窶冱 High School Reunion, but by 3M scientists Spencer Silver and Arthur Fry. In 1968, Silver was working as a 3M research chemist when he developed an unusual adhesive made of tiny acrylic spheres窶敗ticky enough to hold papers together, but weak enough to peel away cleanly and be reused. Because the microspheres touched surfaces at only a few points, the adhesive retained its tack even after repeated use. For years, 3M struggled to find a practical consumer use. A prototype bulletin board coated with the adhesive failed when dust and dirt reduced its sticking power. Silver窶冱 creation remained a solution in search of a problem窶盃ntil Fry, a 3M product development specialist, found one. While singing in his church choir, Fry grew frustrated when the paper bookmarks he used kept slipping out of his hymnal. Recalling Silver窶冱 adhesive from a company seminar, he realized it could anchor a bookmark without damaging the page. Soon, colleagues began using the sticky slips to write notes and reminders, revealing a far broader use. 窶廬 thought what we have here isn窶冲 just a bookmark,窶� Fry later said. 窶廬t窶冱 a whole new way to communicate.窶� After test-marketing the product as 窶弃ress 窶冢 Peel窶� in four cities in 1977, 3M rebranded and launched 窶弃ost-it Notes窶� nationwide three years later. They quickly caught on. 窶廬t was always a self-advertising product,窶� Fry said. People 窶忤ould look at it, peel it off and play with it, and then go out and buy a pad for themselves.窶� Today, Post-it Notes remain one of 3M窶冱 most recognizable products. For their sticky creation, Fry and Silver were inducted into the National Inventors Hall of Fame in 2010. 73 de Scott KF5JRV Pmail: KF5JRV@KF5JRV.#NWAR.AR.USA.NA Email KF5JRV@gmail.com
