In 1968, 3M scientist Spencer Silver accidentally developed a weak adhesive while trying to create a strong one.The weak adhesive did not find any use until fellow scientist Art Fry had the idea of using it for removable bookmarks.This led to the creation of the iconic Post-it Note in the late 1970s.The power of storytelling is exemplified by the fact that the story of the invention of Post-it Notes is memorable and shareable.
