沾不湿的纸

今天，我走在上学的路上，心想：今天又会做什么样的游戏呢？到了学校，我才知道今天要玩“沾不湿的纸”的游戏。纸怎么可能会沾不湿呢？那就让我们来看一下吧！

Today, I was on my way to school, thinking: what kind of game will I play today? When I got to school, I knew that I would play the game of "wet paper" today. How can the paper not get wet? Let's have a look!

叮铃铃，上课了，只见讲台前放着一大桶水，然后，我帮杜老师把水桶抬到讲桌上，杜老师又拿来一个杯子和三张从旧拼音本上撕下来的纸，把那三张纸揉成一个团，塞进杯子里，用铅笔捅了捅，直到不掉下来为止，又慢慢地把杯子倒过来往下压，这时，杜老师卖了个关子，问我们：“你们猜，纸湿了吗？”有的同学说湿了，有的同学说没湿。杜老师拿出杯子来，又用两只手指把纸夹出来，同学们一把抢过来摸了摸，居然没湿！我们感到很奇怪，杜老师告诉我们:“往下压时，有一部分空气留在了杯子内，空气把水和纸隔开了，所以纸没湿。”原来是科学道理，我们一直以为是杜老师会变魔术呢！

Jingling bell. After class, I saw a big bucket of water in front of the platform. Then I helped Mr. Du to lift the bucket to the desk. Mr. Du took another cup and three pieces of paper torn from the old Pinyin book, crumpled the three pieces of paper into a ball, put them into the cup, poked them with a pencil until they didn't fall off, and slowly poured the cup down. At this time, Mr. Du sold them Then he asked us, "guess, is the paper wet?" Some students say it's wet, some say it's not. Mr. Du took out the cup, and then used two fingers to clip out the paper. The students grabbed it and touched it, but it wasn't wet! We feel very strange, Mr. Du told us: "when we press down, some air is left in the cup. The air separates the water from the paper, so the paper is not wet." It turned out to be scientific. We always thought that Mr. Du could do magic!

这次实验真有意思！

This experiment is really interesting!
