You know the person cannot leave salt, salt can make food, but do you know salt can do a test -- side egg " learn light skill " ? Do not believe, let me be decoded for you.
你们知道人离不开盐，盐可以做菜，但你们知道盐可以做实验——帮鸡蛋“学轻功”吗？不信，就让我为你们解密吧。
We prepare a few tools first: A bag of salt, an egg, a cup, one crock hot water. Above all the cup in replete water, next I poured two spoon salt, later our egg " athlete " enter the water in the cup! At the moment, my heart is pounding, because should succeed immediately. The result makes me disappointed greatly, the egg sank, then I think because salt is added too less,the likelihood is. Then, I added 3 spoon salt again, egg " athlete " enter the water again swim. The miracle appeared, egg athlete is in water rock a few float on surface, this but can saying to go up really is " float on water of small meritorious service " , up-to-date still float to go up in surface!
我们先准备一些工具：一袋盐，一个鸡蛋，一个杯子，一壶热水。首先把杯子里装满了水，然后我倒了两勺盐，之后我们的鸡蛋“运动员”就下水杯里啦！此刻，我的心怦怦跳着，因为马上就要成功了。结果大大令我失望，鸡蛋沉了下去，于是我想可能是因为盐加得太少了。接着，我又加了三勺盐，鸡蛋“运动员”再次下水游泳。奇迹出现了，鸡蛋运动员在水里晃动了几下就漂浮在了水面上，这可真能称得上是“轻功水上漂”，直到现在还漂在水面上呢！
This experiment looks we are agape, but I have a doubt: Why the egg cannot float in clear water rise, OK however in brine? I asked father, father answer says: "Briny density is more than the density of the egg, the egg is complete when immersion, buoyancy is more than gravity, natural with respect to rise. " this scientific principle let me understand among them reason, no wonder egg had saline help, had the ability of small meritorious service.
这个实验看得我们目瞪口呆，可是我有一个疑问：为什么鸡蛋在清水里不能漂起来，在盐水里却可以呢？我问了一下爸爸，爸爸回答说：“盐水的密度大于鸡蛋的密度，鸡蛋完全浸没时，浮力大于重力，自然就上浮。”这个科学原理让我明白了其中的道理，怪不得鸡蛋有了盐的帮助，拥有了轻功的本领。
There is science everywhere in the life, want you to be good at observation only, it is OK to start work discovery is secret.
生活中处处有科学，只要你善于观察，动手就可以发现秘密。
