If you've ever played with soap and water, you've probably played with bubbles. The people in this picture are surrounded by a bubble as tall as they are, but most bubbles are much smaller.

There are lots of ways to play with bubbles. You can blow them, chase them, pop them or even just watch them. One of the most fun parts of watching bubbles is looking at all the different colors. Do you know what gives bubbles their rainbow-like color?

The color of a bubble changes, and different spots on one bubble have different colors. The way the light goes through a bubble can change what color the bubble is. The color of a bubble's wall also changes as the bubble gets thinner or thicker. Where the walls of the bubble are at their thickest, the bubble will look blue-green. As they get thinner, they will turn blue, then a purple-red color, then yellow.

When a bubble gets very, very thin it will become totally clear. When it looks like that, the walls of the bubble are only one billionth of a meter thick! Of course, you won't see a clear bubble for very long. When the walls of a bubble are this thin, it's about to pop.(Kayleen Hartman, Staff Writer)

假如你曾經玩過肥皂水,你大概就玩過泡泡。照片中的人被和她們一樣高的泡泡圍住,但大多數的泡泡都小多了。

玩泡泡的方式五花八門。你可以吹泡泡、追泡泡、弄破泡泡或僅僅觀賞它們。觀賞泡泡最有趣的一部分,就是欣賞各種不同的顏色。你知道是什麼賦予泡泡彩虹般的顏色嗎?

泡泡的顏色會改變,不同部位的顏色都不一樣。光線穿過泡泡時,會改變泡泡的顏色。泡泡膜的顏色也會隨著它變薄或變厚而改變。當肥皂泡泡膜達到最厚時,泡泡會呈現藍綠色。當泡泡膜愈來愈薄時,顏色會變藍,再由紫紅色轉成黃色。

當泡泡變得很薄很薄時,幾乎呈透明無色。如此一來,泡泡膜只有十億分之一公尺厚!當然,你無法長久盯著透明的泡泡看。因為泡泡膜這麼薄時,很快就會破了。
