Post-It Notes Were Invented By Accident

There were actually two accidents that lead to the invention of the
Post-It note.  The first was by Spencer Silver.  According to the former
Vice President of Technical Operations for 3M Geoff Nicholson (now
retired), in 1968, Silver was working at 3M trying to create super
strong adhesives for use in the aerospace industry in building planes. 
Instead of a super strong adhesive, though, he accidentally managed to
create an incredibly weak, pressure sensitive adhesive agent called
Acrylate Copolymer Microspheres.
