Those particles hit the next set of adjacent particles, and so on , thereby creating an expanding shell of air particles just bouncing into one another This is called a pressure wave or sound wave.

这些粒子撞击下一组相邻粒子，依此类推，从而产生一个膨胀的空气粒子壳， 只是相互反弹。 这称为压力波或声波。

So for the rest of this episode of our show, we're gonna follow Alie into an episode of her show as she follows the light bouncing around like a little lightning bug like she does into the dark.

拉蒂夫：因此，在本集节目的其余部分中，我们将跟随艾莉进入她节目的一集，因为她就像一只小闪电虫一样跟随光线弹跳，就像她在黑暗中所做的那样。

Even though popping the balloon makes a relatively simple sound when we take a cross section and zoom in on a molecular level we can see the complex pattern depicting how the air particles are bouncing into one another.

尽管气球爆裂的声音相对简单，但当我们取其横截面并放大到分子水平时，我们可以看到描绘空气粒子如何相互弹跳的复杂图案。
