沙漏是一件古老的器具,它在时钟未发明前被用来测量每日的时辰。时钟问世之后,沙漏就完成了它的历史使命。有一个人尝试着把它作为一种玩具来生产销售,倒也不失为一种富有创意之举。但沙漏作为玩具的趣味性不强,孩子不大喜欢它,因此销量也就很小。渐渐的,这个人的沙漏几乎要停产了。有一天,这个人看到别人在长时间的打电话,并因为无法控制话费而苦恼,一个构思立刻浮现在他的脑海:做一个限时3分钟的沙漏。在3分钟内,沙漏上的沙就会完全落到下面。如果把它装在电话机旁,打长途电话时就不会超过3分钟,话费就可以有效的控制了。这个东西在设计上非常简单,把沙漏的两端嵌上一个精致的小木板,再接上一条铜链,然后用螺丝钉钉在电话机旁就行了。不打电话时还可以作为装饰品,看它点点滴滴落下来,虽是微不足道的小玩艺,也能调剂一下现代人紧张的生活。担心话费支出的人很多,新沙漏

An idea immediately came to his mind: Make an hourglass that lasted for three minutes. Within 3 minutes, the sand on the hourglass will fall completely below. If it is installed next to the telephone, it will not take more than 3 minutes to make long-distance calls. The charge can be effectively controlled. This thing is very simple in design, the end of the hourglass embedded in a fine wooden board, then add a copper chain, and then screwed on the phone next to the line. When you don’t call, you can also use it as an ornament to watch it bit by bit. Although it is a trivial gadget, it can also adjust the stressful life of modern people. There are a lot of people worried about the expenses of the call, the new hourglass
