This invention, commonly used in offices and households throughout the world, came about as a result of a series of accidents. In 1968 Spencer Silver, who was working for a company called 3M at the time, was trying to produce super-strong adhesive, a substance making things sticky together, to be used in the building of planes. This, however, wasn’t successful and instead he succeeded in creating an extremely weak adhesive that was 31 to pressure. This new adhesive had two advantages: it could be removed from surfaces quite easily and it could be reused. In spite of these two 32 features, nobody could see any practical use for it. In the end, the invention was 33 .
A few years later, Art Fry, a product development engineer working for 3M, decided to use this adhesive for 34 use. He stuck strips of paper in a book as page marker and a whole new concept was born. However, the idea still wasn’t without 35 . The challenge was to make the glue stay on the sticky note itself, rather than peeling off and staying on the surface it was 36 to. Two more 3M employees were brought in and set the task of producing a coating for the adhesive so that it wouldn’t come off and they 37 just that. Unfortunately, 3M bosses still believed that this invention wasn’t going to be 38 successful and people would continue to use crap paper(小紙條) for their notes rather than sticky notes. This is why sticky notes were only tested within the company, where they became extremely popular. It wasn’t until many years later that 3M bosses finally decided to give out a vast amount of free 39 to other companies to see if anyone would be interested in buying them. To their surprise, 90 per cent of the companies approached went on to order more sticky notes. This went beyond anybody’s 40 . Nowadays, sticky notes come in a variety of shapes and colours and are sold in more than 100 countries.
