I had done a lot of tests, each experiment can let us understand a reason. Today, our class should do a test, the name cries: “ blows eternal flame ” .

我做过很多实验,每一个实验都可以让我们懂得一个道理。今天,我们班要做一个实验,名字叫:“吹不灭的火苗”。

I heard this name, it is the doubt of full head, very open-eyed still! How can there be “ to blow eternal flame ” on the world? Is flame whiff destroyed? The power of flame is very little, can you have play eternal possibility?

我听了这个名字,是满脑的疑问,还很惊讶!世界上怎么会有“吹不灭的火苗”呢?火苗不是一吹就灭了吗?火苗的威力很小,会有吹不灭的可能吗?

Do an experiment to must have experimental stage property, the prop that does this test has lighter and a piece of white paper. When the teacher takes out white paper, I feel very open-eyed, the teacher takes white paper what to is used, not be to be burned more jump over flourishing. The teacher becomes white scroll again funnel form, I feel to resemble a horn, also resemble a bullet.

做实验一定要有实验的道具,做这个实验的道具有打火机和一张白纸。老师拿出白纸的时候我感觉很惊讶,老师拿白纸有什么用,不是越烧越旺吗。老师又把白纸卷成漏斗形,我觉得像一个喇叭,也像一枚子弹。

We ask the test that fine horse of Gong fine jade does first. He has a stage property is funnel. He uses funnel small head forward oneself mouth, outside big head day. We are confident to him, believe he is blown certainly seedling of put out a fire. Fine horse of Gong fine jade began a composition to blow flame, but he uses again great strength to also blow eternal flame, flame still is dancing gladly instead, flame seems to saying: “ with respect to your this galley proof, still want to blow destroy I. ”

我们先请龚琪骏做的实验。他有一个道具是漏斗。他用漏斗小头朝着自己的嘴巴,大头朝外面。我们对他充满信心,相信他一定吹得灭火苗。龚琪骏开始作文吹起了火苗,可是他用再大的力气也吹不灭火苗,火苗反而还在高兴的跳舞,火苗好像在说:“就你这小样,还想吹灭我。”

The teacher lets Li Xinchen blow flame again, she is to grab funnel big head forward oneself mouth, outside small head day. I think: She is a schoolgirl, play even the man student eternal, schoolgirl not more blow eternal? Began, she is blown moment flame is cock-a-hoop still at the beginning, arrived finally, flame resembling was applied by Li Xinchen blackart is same, abrupt destroyed. We are open-eyed rise.

老师又让李欣宸来吹火苗,她是拿漏斗大头朝着自己的嘴巴,小头朝外面。我想:她是个女生,连男生都吹不灭,女生不就更吹不灭了吗?开始了,她一开始吹得时候火苗还得意洋洋的,到了最后,火苗像被李欣宸施了魔法一样,突然间灭了。我们都惊讶了起来。

The truth of this experiment is to become when funnel is big aim flame, air current was blown to the outside to disperse, blow young plant of put out a fire not easily, and the small head of funnel to flame when, air current is together with respect to concentration, blow young plant of put out a fire very easily.

这个实验的道理是当漏斗大头对准火苗的时候,气流吹到外面就分散了,不容易吹灭火苗,而漏斗的小头对着火苗的时候,气流就集中在一起,很容易吹灭火苗。

Now my suddenly be enlightened, I must say this test to my young associate to listen, tell interesting truth to them again.

现在我恍然大悟,我一定要把这实验讲给我的小伙伴听,再给他们讲有趣的道理。(文/王皓扬)
