risks of generic viagra I love the behind-the-scenes story of Post-it notes. How many of these little, yellow sorta-stickies are flagged around your house or your office? Did you know they were originally a mistake? A very very fortunate mistake.
https://soils.wisc.edu/wp-content/cache/students/thesis-blog.html As the story goes, Spencer Silver was a chemist and a very smart man. In 1968, he worked in the research labs at 3M. What he was trying to accomplish was a very strong and very quick-drying super glue. But something went awry, and he found himself with an adhesive that couldn't keep its stick. Despite the error, he had a hunch that it came with potential. He just couldn't figure out what that potential was.

The scraps of paper he used to keep the place in his hymnal routinely fell out. This annoyed him. In a beautiful Hallelujah Chorus moment, he realized what he needed was some kind of temporary adhesive, something that would keep the bookmarks in place but be easily removed without damaging the pages.

The idea caught on. After being told by 3M that the company did not have the manufacturing capacity to make these sticky notes, Fry built a machine in his basement and did it himself. The demand outgrew the company's perceived limitations, and Post-it notes went commercial in 1980.
