Who invented sticky notes and why?
In 1968, Spencer Silver, a scientist at 3M’s headquarters in Maplewood, 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.
Was the sticky note invented by accident?
In the late 1960s, a 3M researcher accidentally created a very weak adhesive when he meant to make a strong one. The eureka moment didn’t come until 1974 when Arthur Fry, another 3M scientist, was looking at his hymnal book and wishing he had a bookmark that would attach to the page, but not leave any residue behind.
When was the sticky notes invented?
Since their introduction in 1980, Post-it Notes have become a ubiquitous office product, first in the form of little canary-yellow pads — billions of which are sold annually — and later also in different hues and sizes, some with much stickier adhesives.

What glue is used for sticky notes?
What Glue is Used on Post It Notes? The glue in Post-It® notes is a combination of a pressure sensitive acrylate (PSA) and microspheres, which are synthetic polymers that won’t dissolve or melt down.
How was Post-it Notes a mistake?
Both are made by an adhesive company, 3M, but the sticky stuff on Post-it notes was actually a mistake. In the late 1960s, a 3M chemist named Spencer Silver was trying to make a stronger, stickier glue when he created Post-it’s wan, weak adhesive.
How many sticky notes are in a stack?
12 Pads per pack, 100 sheets per pad. Unique adhesive designed for use on paper or in planners.
Why are sticky notes sticky?
The basic element in the self-adhesive note is, of course, paper. Yellow is the standard color, although assorted color pads are also available. The key ingredient is the unique polymer adhesive which makes the note pads “temporarily sticky” so they may be removed from a surface and reused.
What makes sticky notes sticky?
A Post-it Note (or sticky note) is a small piece of paper with a re-adherable strip of glue on its back, made for temporarily attaching notes to documents and other surfaces. A low-tack pressure-sensitive adhesive allows the notes to be easily attached, removed and even re-posted elsewhere without leaving residue.
What were Post-it Notes originally called?
Press ‘n Peel
3M launched the product under the name “Press ‘n Peel” in 1977 in four cities. Unfortunately, it was not an immediate success. After a successful product test in Boise, Idaho, 3M released the renamed Post-it® Notes nationwide in 1980.
Can sticky notes get you high?
Approximately a decade after Post-it Notes went on the market, the startling discovery was made that the adhesive used in Post It Notes contains a moderately potent hallucinogen, 3,4,5 triphenethyline. This chemical is similar to phenethyline, which is one of the basic isomers in many popular recreational drugs.
Which glue is used in sticky notes?
CG-12181-1 is an acrylic pressure adhesive with the appearance of milky white. One component makes production easier and more efficient. Besides, it is widely compatible with all brands of sticky note machines.
Are sticky notes toxic?
Are Sticky Notes Toxic? Sticky notes are not toxic, which is why they can be composted and sometimes recycled. Spencer Silver, a scientist at 3M, invented the sticky microspheres on the back of Post-its over 50 years ago. These were made safely in a lab and were designed to not be harmful to you or the environment.
Why do sticky notes smell?
A displeasing smell is not only a matter of comfort. Smell indeed mostly comes from solvent, which means it can be a sign of harmful chemicals used in the adhesive that you’re going to put your hands on and let evaporate in your working space for days.

Are sticky notes wasteful?
Sticky notes, just like every other piece of paper, are bad for the environment. Therefore, they need to be disposed of properly. Paper counts as a biodegradable material, and they are materials that microorganisms can decompose. When decomposition happens, harmful gases are released into the atmosphere.
