our sticky yellow friends
the adhesive for post-its was invented in the late 1960s by accident when a 3m researcher was trying to develop a strong adhesive. however, he ended up developing a rather weak adhesive, and a few years later a colleague used it to make bookmarks. prototypes of post-its were available in the late 70s, and in 1980 they were introduced worldwide. not that i have ever really contemplated post-its before, but i had no idea they were as old as my brother.
