In 1968, Spencer Silver, a scientist at 3M, was working to create a strong adhesive. Accidentally, he developed a new material that was light enough to easily remove and peel apart. Silver felt that he had invented something unique and useful but struggled to find what that use could be. He spent five years meeting with others at 3M, trying to find someone who could recognize the unique capabilities of his invention and create a new product with it.
