Silver's at 3M, was singing in his church choir. For the next five years, he promoted his new invention within 3M, but no one could think of a way to use it. Silver had a new invention, but he didn't know what to do with it. He was trying to invent a super-strong adhesive, but he came up with a super-weak one instead.Īt the time, it was a solution without a problem! Dr. Spencer Silver, a chemist at 3M Company, invented a unique, low- tack adhesive that would stick to things but also could be repositioned multiple times. Would you believe that they're a wonderful invention that happened totally by accident? It's true! In school, at work, and at home - everywhere you go, people have and use sticky notes all the time. People all around the world use sticky notes every day. Today, sticky notes can be found in a wide variety of sizes, shapes and colors. Post-it ® notes started out as three-inch squares that were canary yellow in color. The adhesive allows the notes to be attached to a wide variety of documents and surfaces - and removed and reattached multiple times. Sticky notes - also known as Post-it ® notes or repositionable notes - are small pieces of paper that feature a light adhesive on the back.
