" the science in game " it is the popular science book that introduces from Germany originally. Its graph Wen Bingmao, fascinating, get wide readership especially teenage people welcome. 20 many special subject, 400 many items are distributed in this book, every project is to use the material beside us to have a few interesting tests. Among them the coin ” that ” of strange flower of “ double color and “ are not afraid of storm makes me most exclaim unceasingly.
《游戏中的科学》是一本从德国引进的科普书。它图文并茂，引人入胜，受到广大读者特别是青少年们的欢迎。在这本书分20多个专题、400多个项目，每个项目都是利用我们身边的材料进行一些有趣的实验。其中“双色奇花”和“不怕风暴的硬币”最令我惊叹不已。
” of strange flower of “ double color is what opening to be spent in vain is peduncular become 2 from the analyse intermediate, in the vitreous tube that inserts two to installing the red that passes with clear water dilute and green respectively. Want a few hours only, flower can turn a half into the double color strange flower with red, green half. Why to meet such? Original, beautiful flower is need nutrient is alimentary, and plant root ministry sucks fetch nutrient from inside clay. The moisture that the root absorbs and nutrition work to be carried toward flower and leaf through floral. In us in this experiment, peduncular (namely floral is dry) when carrying water to the flower, also sent dye, then we saw color from leaf, and of both sides peduncular feeding color is different, this formed ” of strange flower of “ double color. Be very magical?
“双色奇花”是把一朵开着白花的花梗从中间剖成二条，分别插入两只装着用清水稀释过的红色和绿色颜料的玻璃试管里。只要几个小时，花朵就会变成一半红、一半绿的双色奇花了。为什么会这样呢？原来呀，美丽的花朵是需要养分滋养的，而养分则是植物根部从泥土中吸取来的。根吸取的水分和营养通过植物的干往花和叶输送。在我们这个实验里，花梗（也就是植物的干）把水输送给花的时候把颜料也送了过来，于是我们就从花瓣上看到了颜色，并且两边的花梗输送的颜色不同，这就形成了“双色奇花”。是不是很神奇？
And “ is not afraid that the coin ” of storm is more magical. Experimental composition is so do: Insert 3 bastinado pin on a ligneous platform first, place into the appearance of “ triangle ” , next superpose of one bastinado coin. At this moment, if you do not master among them mystery, do not want to give coin be blown. However, when this mystery says very simple —— to encounter the surface of coin and smooth brim when air current, most air current passes from the aperture midstream below coin and abate the atmospheric pressure below. And air current is little above coin, atmosphere is normal. Then the fluctuation in coin appeared 2 times pressure is poor, this pressure difference presses coin firmlier in “ on 3 legs ” . It how should we blow ability then is good how should we blow ability then? We can put chin on mesa, extend labium to be blown to coin bottom, air current just can come up against coin fitly below, make coin falls down thereby. Be very simple? Actually simple not at all, but this involves an aerodynamics, flying function flies on a day also was to use such principle!
而“不怕风暴的硬币”就更神奇了。实验作文是这么做的：先把三杖大头针插在一个木制平台上，摆成“三角”的形状，然后把一杖硬币放在上面。这时，如果你不掌握其中的奥秘，就甭想把硬币给吹下来了。然而，这个奥秘说起来很简单——当气流遇到硬币的表面和光滑的边缘时，大多数气流从硬币下面的缝隙中流过而减弱了下面的气压。而硬币上面气流少，大气压正常。于是在硬币的上下二面出现了压力差，这个压力差就更牢地把硬币压在了“三条腿”上。那我们该怎么吹才好呢？我们可以把下颚放在台面上，伸出下唇向硬币底部吹去，气流就会恰恰好碰到硬币下面，从而使硬币掉下来。是不是很简单？其实一点也不简单，这可是涉及到空气动力学，飞机能飞上天也是用了这样的原理！
This book involved several manage to change, the many course such as astronomy, geographical, biology, it told us a lot of interesting knowledge not only, still let us play not little game, more aroused our infinite to science curiosity. Dear young associate people, everybody makes game quickly together!
这本书涉及了数理化、天文、地理、生物等多个学科，它不仅告诉了我们许多有趣的知识，还让我们玩了不少的游戏，更激发了我们对科学无限的好奇心。亲爱的小伙伴们，大家快来一起做游戏吧！(文/小蜗牛的足迹)
