today i learned – fri 28th dec 2018

ever wanted to stumble across an amazing invention by accident? well, that’s what happened with the postit note! ๐Ÿ˜ฑ

#tdil that sticky notes were actually created as the result of two different accidents by a singular dude ๐Ÿ™ˆ

the dude in question is actually named spencer silver ๐Ÿ‘จ๐Ÿป. in 1968 he worked for 3m and was tasked with creating aerospace grade, super strong, adhesives … like, adhesives for sticking planes together! โœˆ๏ธ

unfortunately, what he actually created was an adhesive agent named โ€˜acrylate copolymer microspheresโ€™ … whilst it was super weak, it was pressure sensitive, left no residue and was reusable ๐Ÿ‘๐Ÿป

problem was, 3m had no use for a weak adhesive that had pretty much zero use whatsoever ๐Ÿ˜… #awks. eventually, management did have an idea and decided to use the adhesive around the edge of bulletin boards, so that peeps could stick paper to it (kind of like a reverse post-it note).

well, he couldnโ€™t catch a break until choir singer and 3m product development engineer, art fry, came up with accident number two.

you see, fry regularly had an issue with song markers in his hymn book going missing ๐Ÿ˜’ … so he decided that silverโ€™s adhesive could come in handy.

fry and silver decided that the bulletin board idea was backwards – the adhesive should be on the paper! then it can stick to anything #thepossibilitesareendless.

at first, they had a merh as the adhesive would often stay stuck to the object when the paper was removed ๐Ÿ™ƒ … lots of work went into it (seven years of work and subsequent rejection to be exact) and eventually they managed to fix the issue ๐Ÿ˜

peace out ๐Ÿ˜Ž #tdil


i genuinely enjoyed this one, thatโ€™s two in a row! ๐Ÿ˜ฑ if youโ€™d like to read some more good stuff, you just need to go ->here<-
