It all started with Spencer Silver was working in 1968 that the company 3M trying to develop a super-strong adhesive-extra-strong-powerful mother (would say our children) that could be used for the construction belle vue aces of airplanes in the aerospace industry. And think about it, instead of the incredible glue, by mistake the machine spat out a sticker incredibly weak that he could not hold together even aereoplanini paper. Let alone those aerospace. Poor Silver was mocked by the middle management of 3M. Ineffective. Useless. Too weak to be useful.
But this poor little sticker, the result of an error industrial, had two interesting features: the first is that when it was attached to a surface, could be easily removed without leaving belle vue aces any residue of glue thanks to acrylic microspheres of which was composed. The second is that it was reusable. Attack-off-riattaca-is-amazing-attacked ristaccalo? -you Riattacca- great!
Silver was amazed by his invention but had no use. He was carrying a product that was not marketable and therefore useless in the eyes of the world. So Silver spent five years presenting his product to the employees of 3M hoping cavarci something, hoping that someone found a way to use'm adhesive. But nothing doing. Without a purpose, without a manual, it was unsaleable. Then shelved.
Until, in 1973, joined belle vue aces a second "accident" of course. A chemical belle vue aces engineer at 3M, Art Fry, in addition to being a researcher in the product development division, was a member of the choir of the North Presbyterian Chuch of North St. Paul, Minnesota. Every Sunday he never failed to commissioning. As he sang, came his constantly in a trivial but annoying problem. To find such an early stage the songs to be performed, it was usually put in the book of songs some sheets of paper at the songs chosen. belle vue aces But they were more often as the package, opening the book fell, then had to pick them up, he lost the sign of the page (where are we? Gira! No there, no, after the singing. SHHHH!) And those in which they carried out their function as we must. "WHERE TROVEREMOOO Panee ALL SO MUCH FOR SFAMAREEE GENTEEE". Art Fry says:
Suddenly I had the idea of an adhesive ... not any of an adhesive; one of which was designed and tested by one of my colleagues at 3M, Spencer Silver, but that was then was discarded because it had the disadvantage of losing its adhesive strength after a short time. "
The bulb of Fry had turned suddenly. ALLELUJIA ALLELUJA. The returned in mind That adhesive threw away years before. To solve the problem for leaflets flew away was enough to make them sticky so that remain attached to the pages of the book, without belle vue aces damaging them, and being able to be removed belle vue aces when no longer needed that take the sign. Needed in short, a "sticker belle vue aces to keep it that only a short time."
The following Monday, Fry went to work as usual. The idea gained in church on Sunday belle vue aces the mix for the head, and deconcentrandolo belle vue aces by revealing that in fact the possible applications of such an invention would have to go well beyond the use that he thought the missal. He decided to develop his idea, recovering the adhesive and fellow belle vue aces explaining that if the sticker was placed behind a piece of paper, could be attacked anywhere. It took a year and a half of work. He went in the commercial office to propose his invention, but was greeted with suspicion. Indeed, they say with absolute indifference. Ah ... good ... good, singing, but for me is NO. Would you say the Mara Maionchi.
3M agreed to do a test market, selling a product sample in 4 cities of the United States, belle vue aces as the Post-it. And, you will think: finally did it ... no. The results were very bad.
However, the then head of the laboratory of 3M products, Geoff Nicholson, did not want to give up the bone. He realized that if they had not been successful, it was not the fault of the Post-it, but as they had been put on the market. The post-it had been placed on the shelves without advertising or promotions. It was then a marketing problem. Strategies. Therefore, for the umpteenth time was planned relaunch of the product on the market, after distribution of free samples in supermarkets and offices. All right. They went like hot cakes. It was the joy of the secretaries and all employees. Since 1980 was the widespread sale of Post-it in the United States belle vue aces and the following year landed in Europe and then in the rest of the world.
From this story I learned a lot of things. That if you
