Did you know custom 3M Post it Notes were created by accident?
While attempting to develop a super-strong adhesive at 3M, a scientist accidentally created a low-tack, reusable and pressure-sensitive one. Without a functional purpose at the time, the idea as a paper reminder circulated internally at 3M until Press n’ Peel was released in 1977. With poor sales, that name didn’t stick; thus the Post-it Note was born. Ironically, I used one to remind me to write this post tonight!
