DID YOU KNOW ?

The invention of Post-it-Notes was by Spencer Silver in 1974.
Spencer Silver was working in the 3M research laboratories in 1970 trying to find a strong adhesive.
Silver developed a new adhesive, but it was even weaker than what 3M already manufactured.
It stuck to objects, but could easily be lifted off.
It was super weak instead of super strong.
No one knew what to do with the stuff, but Silver didn’t discard it.
Then one Sunday four years later, another 3M scientist named Arthur Fry was singing in the church’s choir.
He used markers to keep his place in the hymnal, but they kept falling out of the book.
Remembering Silver’s adhesive, Fry used some to coat his markers.
Success! With the weak adhesive, the markers stayed in place, yet lifted off without damaging the pages.
3M began distributing Post-it ® Notes nationwide in 1980 — ten years after Silver developed the super weak adhesive. Today they are one of the most popular office products available.
