There's a bit in Wonderful World that has to do with Post-it Notes so we did some research into this seemingly ubiquitous office product and learned some fun stuff. Here goes, courtesy of the inventor, 3-M.

Then, six years later, a colleague of Dr. Silver, Art Fry, remembered the light adhesive when he was daydreaming about a bookmark that would stay put in his church hymnal. The rest is history.
- Post-it Notes were introduced to the American market in 1980 by the 3M Company.
- A Post-it Note weathered a flight from Las Vegas to Minneapolis on the nose of the plane. It endured speeds of 500 mph and temperatures as low as -56 degree Fahrenheit.
- In 1989 a family left a Post-it® Note on their front door during Hurricane Hugo and it was there 3 days later. Their trees weren’t.
