Well, we do similar things.

嗯,我們也做類似的事情。
He, he didn't think his kite was going to get struck, and he thought that if it was going to get struck that he wouldn't get hurt.
他不認為他的風箏會被擊中,他認為如果風箏被擊中,他是不會受傷的。
So, he was wrong there.
他錯了。
If the kite had been struck, he probably would have been killed, as have many people flying kites.
如果風箏被擊中,他可能會命喪黃泉,就像許多放風箏的人一樣。
They load a rocket and launch it into the belly of a thundercloud.
他們裝載火箭,把它發射到雷雨雲中。
From the rocket's tail, a spool of copper wire unwinds creating a path for the lightning to follow.
從火箭尾部,一卷銅線展開,為閃電創造了一條路徑。
There's a level of excitement and tension before you push the button,
在你按下按鈕之前會有一種興奮和緊張的情緒,
and then there's a level of, of holding your breath for two seconds when the rocket goes up that's unlike anything else.
當火箭升空的時候,屏住呼吸兩秒鐘,這是不同於其他任何感受的。
And, success feels real good because we, you know, we only make it happen ... twenty, twenty-five times a summer, so every one is a, is a big deal.
成功的感覺真的很好,因為我們只會讓它發生……一個夏天發生二十次、二十五次,所以每一次都是一件大事。
It's like a rocket-powered lightning rod.
它就像裝有火箭發動機的避雷針。
Once the wire is shot up into the air the lightning hits it.
一旦電線被射入空中,閃電就會擊中它。
In an instant, the electric current of the bolt moves down the wire disintegrating it into a green vapor.
瞬間,螺栓的電流沿着電線向下移動,將其分解成綠色蒸汽。

What flows down the lightning at fifty thousand amps is the same thing that flows in your wall at ten amps.

以5萬安培的電流從閃電中流過的東西和在牆上以10安培的電流流過的東西是一樣的。
The temperature of a lightning bolt is more than fifty thousand degrees Fahrenheit, six times hotter than the surface of the sun.
閃電的温度超過了五萬華氏度,這是太陽表面温度的六倍。
All that heat and light is generated by uncounted numbers of electrons being forced to move.
所有這些光和熱都是由無數電子被迫移動而產生的。
An atom's nucleus has a positive charge.
原子核帶正電荷。
Electrons orbiting the nucleus have a negative charge.
圍繞原子核運行的電子帶負電荷。
When electric current flows, electrons are torn from atoms and move freely.
當電流流動時,電子從原子中被撕裂並自由移動。
Electricity is the flow of electrical charge, and most of the charge flows as, as electrons moving.
電是電荷的流動,當電子運動時,大部分電荷都是流動的。
Whenever there's an oversupply of electrons an object develops an overall negative charge.
每當電子供應過剩時,物體就會產生負電荷。
Nature balances things out with equal positive charges somewhere else.
大自然在其他地方用相等的正電荷來平衡事物。
The potential difference between the charges is measured in volts.
電荷之間的電位差是用伏特來測量的。
Electric current, anything from static electricity to lightning bolts, is electrons moving from negative to positive.
從靜電到閃電的任何電流都是電子從負向正移動。
It seems like it's easier to make sparks and lightning than not to make them.
似乎製造火花和閃電要比不製造容易。
Anytime you have two dissimilar materials rubbing together you get sparks.
當你有兩個不同的材料摩擦在一起,就會產生火花。
