A day, father and I saw in a physical book one writes a composition about atmosphere experiment, I want to look is what principle, then, began a test.
一天，爸爸和我在一本物理书里看到了一个关于大气压的实验，我想看看是什么原理，于是，就开始了实验。
Preparative material has: Water bottle of an a birdbath, mineral spring, a few water and a piece of chipboard. Above all we want to hold birdbath and mineral water bottle full water, put chipboard on the opening of mineral water bottle next, come over mineral water bottle again, the mouth is gadarene, put in the water of birdbath. Next, be the one step with this the most important test. We should smoke chipboard quickly, remember, an opening of mineral water bottle does not want to leave surface when smoking chipboard, such water come out with respect to meeting shedding, the experiment failed. Finish successfully after this one pace, we can discover, the water in mineral water bottle did not flow actually! Is this why? I checked a data to just know, so we live in the earth's surface, although air is very light, but the air above us is particularly much, can press water so, do not let current come out.
准备的材料有：一个水盆、一个矿泉水瓶、一些水和一张硬纸板。首先我们要将水盆和矿泉水瓶装满水，然后把硬纸板放在矿泉水瓶的瓶口上，再把矿泉水瓶倒过来，口朝下，放在水盆的水里。接下来，就是这个实验最重要的一步了。我们要把纸板快速的抽掉，记住，抽纸板的时候不要把矿泉水瓶瓶口离开水面，这样水就会流出来，实验就失败了。成功做完这一步后，我们就会发现，矿泉水瓶里的水竟然没流出来！这是为什么呢？我查了一下资料才知道，原来我们生活在地表，虽然空气很轻，但是我们上面的空气特别多，所以能压着水面，不让水流出来。
How, this experiment is very amused. Pass this test, I deepened understanding to the physical phenomenon of atmosphere. Really " practice gives genuine knowledge " ah!
怎么样，这个实验是不是很好玩。通过这个实验，我对大气压的物理现象加深了理解。真是“实践出真知”啊！
