Franklin's Famous Kite Experiment
In the eighteenth century, Benjamin Franklin conducted a number of experiments in which he
showed what electricity is. Here is how he described one of his experiments.
In June 1752, I wanted to show that lightning and electricity are the same. Having realised that I could use a kite to attract lightning, I decided to do an experiment. I built a strong kite and waited for bad weather. When the first thunderstorm came, I took my condenser to a shed in the fields where I could do my experiment. My son helped me fly the kite.
The kite flew high in the rainy sky, but nothing happened. I was beginning to think that the
experiment would not work. Just then, I saw some of the hairs on the string stand up. The string was
getting charged! I brought my finger close to the key and felt a light but very dear electric shock. Others followed even before the whole string was wet, and I was able to collect and store a great deal of electricity in the condenser. This experiment proves that lightning and electricity are the same.
To do the experiment you need four things: a kite, a key, some really bad weather and a condenser,to store electricity. Most kites are made of paper, but a kite made of silk will not tear so soon in weather with rain and strong winds. Build the frame of the kite by making a small cross of two pieces of light wood. The pieces should be just long enough to reach the corners of the handkerchief. Tie the corners of the handkerchief to the points of the cross, and you will have a nice strong kite. Add a tail to the frame and tie a long string to the cross so you can control the kite.
The next three steps are very important. First, fix a very sharp piece of metal, pointing a foot or more above the frame, to the top of the longer stick of the cross. Second, fasten a key to the end of the long string. Third, tie a silk ribbon to the string, just above the key. This ribbon, which must not get wet, will protect you from the electricity.
Fly the kite when a thunderstorm appears to be coming on. Stand inside a door, or under some cover,so that the silk ribbon does not get wet. Take care that the string does not touch the wall or the door.When a thundercloud comes over the kite, the sharp piece of metal will pull the electricity from the cloud. The kite and the string will become charged. When the kite and the string are wet from the rain, they will conduct the electricity very well. You can collect and store the electricity in the condenser and use it for other experiments.

富兰克林的著名风筝试验在18世纪,本杰明富兰克林进行了一系列试验,他在其中说明了什么是电力。下面是他其中一个实验的描述。
1752年6月,我想说明,闪电和电是一样的。想到我可以用风筝引电,我决定做一个实验。我制作了一个大而牢固的风筝然后等待着恶劣的天气。当第一次雷雨到来时,我把我的冷凝器放在田间的棚中,我可以在那里做我的实验。我儿子帮我放风筝。
风筝在雨季的天空中飞行的很高,但却什么都没有发生。开始我以为实验是行不通的。就在那时,我看到的绳索上的发丝站立起来了,并且越来越严重。我把我的手指靠近钥匙,我觉得有些轻微但却是真实存在的电击。在整个绳索湿了之后,其他的闪电紧随其后,我能在冷凝器中收集和储存大量的电力。这个实验证明,闪电和电是相同的。
为了做实验,你需要四样东西:一个风筝,一把钥匙,非常恶劣的天气和一个来储存电能冷凝器。大部分的风筝是纸做的,但丝绸制的风筝,不会这么快在雨和强风中撕裂。风筝的框架是用交叉的2个小的轻木十字架制定的。它应该有足够的长,能够达到手帕的一角。把手帕的一角绑在交叉点上,这样你将会得到一个不很强壮的风筝。在框架上加一个尾状物, 并且系一根长的绳索,这样你可以控制风筝。
接下来的三个步骤非常重要。首先,固定一个非常锐利的金属片,使他指在框架一英尺或更高的位置,指向对十字架的长棍的顶部。其次,在长绳的尽头挂上一把钥匙。第三,在钥匙上方的绳索上系一根丝带。这丝带绝不能淋湿,他将保护你避免你触电。
在暴风雨快要到了是开始放风筝。你要站在门内,或在躲在某些遮盖之下,这样丝绸才不会弄湿。注意不要让丝带接触墙壁或门。.当雷电来时,锐利的金属片将会从云层中引来电,而风筝和钥匙将会被充电。当风筝和钥匙在雨中淋湿时,他们将会很好的引来电力。你就可以将电力收集并储存在电容器中,并用于其他实验。
