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。

It’s no secret that Japanese people have a deep affection for noodles. Like in the rest of East Asia, noodles are an important staple food, second only to rice. Japanese people have enjoyed noodles for over 1,000 years. The first noodles came from China and were introduced around 800 CE. As time passed, noodles in Japan not only became widespread but also developed some unique Japanese characteristics. The three most popular types of noodles in Japan are ramen, soba, and udon. Ramen, typically made from wheat flour, is usually thin and firm. The dough is kneaded and left to
Rice is an essential ingredient in Taiwanese cuisine. Many foods are made of rice, adding more variety to our cooking, such as rice cake, or “gui.” Wagui is made by steaming rice flour batter in a bowl. The term “gui” refers to a type of food made from rice, while “wa” refers to a bowl. The pronunciation of “gui” in Taiwanese Hokkien is similar to the word for “nobility” in Chinese, so it is common for people to prepare various types of gui, including wagui, as offerings to the gods or ancestors,. 米是台灣重要的主食,用米製成的食品十分多元,豐富我們的飲食,如米做成的「粿」。粿的意思是米做成的糕點,碗粿是將在來米漿倒入碗中蒸熟,因而得名。粿因為音同「貴」,因此碗粿等粿食常用作供品祭拜神明和祖先。 nobility (n.) 高貴,高尚;貴族 offering (n.) 供品 While Taiwan may not be
On Tuesday last week, the flame for this summer’s Paris Olympics was lit at the birthplace of the ancient Olympic Games in southern Greece in a meticulously choreographed ceremony. It will then be carried through Greece for more than 5,000km before being handed over to French organizers at the Athens venue used for the first modern Olympics in 1896. The pageantry at Olympia has been an essential part of every Olympics for nearly 90 years since the Games in Berlin. It’s meant to provide an ineluctable link between the modern event and the ancient Greek original on which it was initially modelled. Once
Continued from yesterday(延續自昨日) https://www.taipeitimes.com/News/lang As with many aspects of Japanese culture, there is etiquette to follow when you enjoy noodles. To fully experience noodles like a local on your next visit to Japan, consider these simple guidelines. First, be careful where you put your chopsticks. Don’t leave them sticking up in the broth or set them at the side of the bowl. When you have finished eating or if you’re taking a break, place them on the chopstick rest next to the bowl. Also, it is impolite to wave chopsticks around or bring them above mouth-level. Second, don’t take too
