The rubber (橡胶) raincoat was invented by Macintosh in 1823.
In 1492, Columbus discovered the New World the Americas. He brought a lot of things from South America. Rubber was one of them, but people didn't know the use of rubber at that time. In 1770, people found that the rubber could be used as erasers.
Macintosh was a worker in an eraser factory in England. One day he spilled (洒出) the rubber liquid (液体) over his clothes carelessly when making erasers. He was too busy to clean it and went back home wearing the dirty clothes. On the way home, it rained heavily. Having no umbrella, Macintosh had to run home quickly. When he got home, he took off the wet clothes. To his surprise, the area of the clothes with rubber wasn't wet. "Why not make a rubber raincoat?" Macintosh thought. The next day he brushed the rubber liquid all over a coat. He wore the "rubber coat" on rainy days and took a walk outdoors, to test if it could really keep off the rain. Surprisingly, the clothes inside the "rubber coat" weren't wet at all. The rubber raincoat was created in this way by chance.
