The history of zippers
　　拉链的出现是一个世纪之前的事。当时，在欧洲中部的一些地方，人们企图通过带、钩和环的办法取代钮扣和蝴蝶结，于是开始进行研制拉链的试验。　　
1893年，一个叫贾德森的美国工程师，研制了一个“滑动氏没紧装置”，并获得了专利，这是拉链最初的雏形。这项装置的出现，曾对在高统靴上使用的扣钮扣钩造成了影响。但这一发明并没有很快流行起来，主要原因是这种早期的锁紧装置质量不过关，容易在不恰当的时间和地点松开，使人难堪。
　　
1913年，瑞典人桑巴克把金属锁齿附在一个灵活的轴上。其工作原理是：每一个齿都是一个小型的钩，能与挨着而相对的另一条带子上的一个小齿下面的孔眼匹配。
拉链最先用于军装。第一次世界大战中，美国军队首次订购了大批的拉链给士兵做服装。但拉链在民间的推广则比较晚，直到1930年才被妇女们接受，用来代替服装的钮扣。　　
拉链是在1926年获得现在的名称的。据报道，一位叫弗朗科的小说家，在推广一种拉链样品的一次工商界的午餐会上说：“一拉，它就开了！再一拉，它就关了！”十分简明地说明了拉链的特点。拉链这个词是这样来的。

最糟糕的发明
“二十世纪最糟糕的发明是什么 ”就是人们每天大量使用的塑料袋。 诞生于上个世纪三十年代的塑料袋，其家族包括用塑料制成的快餐饭盒、包装纸、餐用杯盘、饮料瓶、酸奶杯、雪糕杯等等。这些废弃物形成的垃圾，数量多、体积大、重量轻、不降解，给治理工作带来很多技术难题和社会问题。 比如，散落在田间、路边及草丛中的塑料餐盒，一旦被牲畜吞食，就会危及健康甚至导致死亡。填埋废弃塑料袋、塑料餐盒的土地，不能生长庄稼和树木，造成土地板结，而焚烧处理这些塑料垃圾，则会释放出多种化学有毒气体，其中一种称为二噁英的化合物，毒性极大。
