Art Fry was a researcher in the 3M Company. He was bothered by a small irritation every Sunday as he sang in the church choir. That is, after he 1 his pages in the hymn book with small bits of paper, the small pieces would invariably fall out all over the floor. One day, an idea 2 Art Fry. He remembered a kind of glue developed by a colleague that everyone thought 3 a failure because it did not stick very well. He then coated the glue on a paper sample and found that it was not only a good bookmark, but it was great for writing notes. It would stay in place 4 you wanted it to. Then you could remove it 5 damage. The resulting product was called the Post-it, one of 3M’s most successful office products.
