On Wednesday the exercise class afternoon, mr. Chen walked into a classroom as usual, can have again today some different. Her demur does not say, take the chalk of a green, 3 words —— was written down earnestly to blow a balloon on blackboard.
星期三下午的作业课，陈老师像往常一样走进了教室，可今天又有些不同。她二话不说，就拿起一只绿色的粉笔，郑重地在黑板上写下了三个字——吹气球。
For Mr. Chen face about: “ classmates, we do this test today. Mr. ” Mr. Chen just said, whole class boiled rise, blow a balloon? Be blown with the mouth namely? What test can you have? The balloon that than who should still blow is big? You visit whole class fellow student I, I see you, do not know the what drug that sells in Mr. Chen calabash. Mr. Chen makes us quiet to come down, oneself move toward desk mysteriously, said voice: “ Mi Mi ! ” subsequently, take the bag of a chocolate from the chair of desk, ha! Be to should eat chocolate? Whole class classmate is staring at that bag closely, do not know within to have what thing.
陈老师转过身来说：“同学们，我们今天就做这个实验。”陈老师刚说完，全班便沸腾了起来，吹气球？不就是用嘴吹吗？能有什么实验？还是要比谁吹的气球大？全班同学你看看我，我看看你，不知陈老师葫芦里卖的什么药。陈老师让我们安静下来，自己神神秘秘地走向办公桌，说了声：“嘛咪嘛咪吽！”随后，从办公桌的椅子上拿起一个巧克力的袋子，哈！难道是要吃巧克力？全班同学紧盯着那袋子，不知里头有什么东西。
Mr. Chen pulls arm, resemble conjure first like took out to installing magical transparent liquid plastic bottle, took out an a few smaller plastic bottle again then, took out two balloons that holding strange object finally. What be in the balloon? Be air or water? In plastic bottle? Countless little unsolved problem skip in disorder in my head frisk.
陈老师挽了挽袖子，先像变戏法儿似的拿出了一个装着神奇的透明液体的塑料瓶，接着又拿出了一个小一些的塑料瓶，最后拿出了两个装着奇怪物体的气球。气球里是什么？是空气还是水？塑料瓶里呢？无数个小问号在我的脑袋里乱蹦乱跳。
Began to experiment! Mr. Chen takes that to install transparent liquid first bottle writes a composition child, tilt bottle slowly, that transparent liquid falls into small plastic bottle, take the balloon that holding strange object only again, pull the mouth blowing air of the balloon big, cover the opening in small plastic bottle cautiously, join the object in the balloon small plastic bottle again in, the balloon ran like seeing the white powder with have a few strange resembles mischievous child only, apace and transparent liquid dissolve for an organic whole. Miraculous happening, mix in white powder of that liquid confluence that momently, produced the foam of a lot of white suddenly, and the balloon of opening, resembling is to have an aeriform inflator like aerating to it, roused slowly unexpectedly. But because power is too great, gave balloon lane a hole, the result turned fountain of bubble of a “ into ” .
开始试验了！陈老师先拿起那个装透明液体的瓶作文子，慢慢地将瓶子倾斜，把那透明液体倒入小塑料瓶中，又拿起一只装着奇怪物体的气球，把气球的吹气口拉大，小心翼翼地套在小塑料瓶的瓶口，又将气球中的物体倒入小塑料瓶里，只见有一些奇怪的白色粉末像顽皮的孩子一样跑出了气球，快速地与透明液体溶为了一体。奇迹发生了，就在白色粉末和那液体融合的那一刻，突然产生了许多白色的泡沫，而瓶口的气球，像是有个无形的充气机在给它充气一样，竟慢慢鼓了起来。可因为力量太大，把气球弄出了一个洞，结果变成了一个“泡沫喷泉”。
Mr. Chen brushs the water on dais, say: “ although the experiment failed, but his chemical principle did not change ” , mr. Chen was written down on blackboard a chain of strange symbol, continue, the object in “ balloon is sodium bicarbonate, bases is bicarbonate natrium, the liquid in bottle is white vinegar, bases is acetic acid. Encounter acetic acid when bicarbonate natrium, generate acetic acid natrium, water to drink carbon dioxide with respect to meeting reaction, is carbon dioxide is blown roused a balloon. ”
陈老师擦了擦讲台上的水，说：“虽然实验失败了，但他的化学原理没变”，陈老师在黑板上写下了一连串奇怪的符号，继续道，“气球里的物体是小苏打，主要成分是碳酸氢钠，瓶里的液体是白醋，主要成分是醋酸。当碳酸氢钠遇到醋酸，就会反应生成醋酸钠、水喝二氧化碳，而正是二氧化碳吹鼓了气球。”
In the life, have science everywhere, want to have a pair of hands that are good at an experiment only, bottle also can blow a balloon.
在生活中，处处都有科学，只要有一双善于实验的手，瓶子也能吹气球。(文/杨陈宇)
