Some inventions are so useful, but seem so simple, that we wonder why no one thought of them long ago. Post-it Notes-the pieces of paper that you can fasten(固定)almost anywhere and then remove without leaving any sign that they were there=are an example of such an invention.
Post-it Notes were invented about twenty years ago by Art Fry, a scientist at 3M Corporation. The idea for the product came from a frustrating(令人沮丧的)experience he often had while singing in his church choir(唱诗班). Fry used pieces of paper as bookmarks to mark the places in his book of songs, but these bookmarks were always falling out. He knew he needed a bookmark that would stay where he put it, but that he could remove without damaging the pages.
Around that time, Fry heard about a new adhesive(粘合剂)that a colleague(同行), Dr. Spence Silver, had created. This adhesive was special because it was sticky, but not too sticky. It was strong enough to hold papers together, but weak enough to not tear the paper when it was removed. Fry saw that the new adhesive could help solve his bookmark problem. One morning, Fry put some of the adhesive on the edge of a piece of paper. Just as he hoped, it made a perfect bookmark.
A short time later, Fry realized that his new invention had even more uses than being a great bookmark. He came to this realization when he wrote a note on one of his new “bookmarks” and attached(附着)it to a report he was going to give to a colleague. Soon, co-workers were asking Fry for more samples (样品)of his invention so that they could use the new type of notes themselves.
Fry and some other people at 3M believed so much in the new product that they persuaded the company to give away thousands of the “sticky pieces of paper” for trial(试验)use. When some salespeople at 3M went to offices and showed workers just how helpful the new type of notes could be, they immediately received many orders. As more and more people discovered how useful Post-it Notes could be, the product took off.
