Handy Post It’s
As with many innovations, the originator of 3Ms sticky yellow Post-its didnt know what he hadat first. Researcher Spence Sliver saw curious about what would happen if he mixed an unusual amount of monomer into a polymer-based adhesive he was working on. The result was an adhesive that would “tack” one piece of paper to another and even restick, without leaving any residue on the second piece of paper. The company had no use for the new adhesive until 3M chemist Arthur Fry began having problems in the choir loft. The slips of paper he used to mark pages in his hymnal often fluttered to the floor, leaving him frantically searching for his place. Then he remembered Silvers adhesive. Frys better bookmark soon metamorphosed into the handy Post-its that have become a fixture in offices throughout the country.
