I hear the person won't sink in the Dead Sea, it is the person that won't swim to also won't sink, do this write a composition after all what reason be? Today, I do an imitate little test, how to let an egg rise in the float in water.
我听说人在死海里不会沉下去，就算是不会游泳的人也不会沉下去，这到底是什么原因呢？今天，我就来做个模拟小实验，怎么让鸡蛋在水中浮起来。
Above all, prepare the material that makes little test. A cup of an unripe egg, clear water, salt and a chopstick. I put unripe egg into this cup of clear water in, I see the egg sinks very quickly.
首先，准备好做小实验的材料。一个生鸡蛋、一杯清水、盐和一根筷子。我把生鸡蛋放入这杯清水里，我看到鸡蛋很快就沉下去了。
Next, my go toing adds salt inside this cup of clear water. I want to add two spoon salt should enough, take chopstick mix, agitate melts adequately to salt. I put in the egg again, I think the egg is sure meeting float rises, did not think of the egg sinks unexpectedly. I think should be salt those who add is too little, so the egg rises without float. I am gone to again 3 spoon salt was added in this cup of clear water, take chopstick mix even, put in the egg again, I think affirmation won't sink again this. Result absolutely did not think of the egg sinks again. Do I begin to suspect this experiment can be false? After I think, the decision added 3 spoon salt in past cup again finally, take a chopstick rapid mix is even, if if float of egg or else rises,I think, this experiment is false for certain. I put carefully slowly again, at this moment, I feel an egg and did not want the meaning that sinks, it eventually float rose, I cried with joy, "Egg float rises! "Egg float rises!!
然后，我往这杯清水里面加盐。我想加两勺盐应该够了，拿筷子搅拌，搅拌到盐充分融化。我再把鸡蛋放了进去，我以为鸡蛋肯定会浮起来，没想到鸡蛋居然沉下去了。我想应该是盐加的太少了，所以鸡蛋没有浮起来。我又往这杯清水里加了三勺盐，拿筷子搅拌均匀，再把鸡蛋放进去，我想这下肯定不会再沉下去了吧。结果万万没有想到鸡蛋又沉下去了。我开始怀疑这个实验会不会是假的呢？我想了想后，决定最后再往杯子里加了三勺盐，拿筷子迅速搅拌均匀，我想如果鸡蛋再不浮起来的话，这个实验肯定是假的。我小心地再把鸡蛋慢慢地放了下去，这时，我感觉到鸡蛋并没有要沉下去的意思，它终于浮起来了，我高兴得叫了起来，“鸡蛋浮起来喽！”
This small experiment tells us, through salt is being added in past clear water, change the proportion of water, density that increases water, when the flotage of water is more than the weight of the egg, the egg rose with respect to float. This is famous Archimedes principle.
这个小实验告诉我们，通过往清水里加盐，改变水的比重、增加水的密度，当水的浮力大于鸡蛋的重量时，鸡蛋就浮起来了。这就是著名的阿基米德定律。
