这个我是在一个外国网站上看到的，由于我英语不是很好，浏览器的翻译软件翻译的结果又读起来不通顺，就没有做，把网站发给大家看，有没有能够看懂的讲一下方法和原理。

A simple homemade Van de Graaff generator
自制一个简单的范德格拉夫起电机
In the previous two projects, we stole high voltage from a television set to power our high voltage motors. In this project we will build a device that can generate 12,000 volts from an empty soda can and a rubber band.
之前，我们从一台电视机获得高压电驱动我们的高压电动机。这次，我们将使用空易拉罐和橡皮筋制作一个能够产生12,000伏特电压的装置。
The device is called a Van de Graaff generator. Science museums and research facilities have large versions that generate potentials in the hundreds of thousands of volts. Ours is more modest, but is still capable of drawing 1/2 inch sparks from the soda can to my finger. The spark is harmless, and similar to the jolt you get from a doorknob after scuffing your feet on the carpet.
这个装置名叫范德格拉夫起电机。科技博物馆和研究所大型设备可以产生数百千伏的电压。我们这个比较低调，但仍然可以从我的手指和易拉罐之间拉出1/2英寸的火花（艾玛呀，不疼吗？）。这样的火花不会对人体产生伤害，就类似于在地毯上面拖着脚走之后被门把手电一下。
