Today, the teacher assigned an interesting task to us, let us come home do a test. You are guessed, what test did I do? Either " dancing wastepaper " , also not be " the music that can see " , right, be " briny float egg " .
今天，老师给我们布置了一个有趣的作业，让我们回家做一个实验。你们猜一猜，我做了什么实验？不是“跳舞的纸屑”，也不是“能看见的音乐”，没错，是“盐水浮鸡蛋”。
Experimental material has: Egg, water, cup, salt, ladle and chopstick.
实验的材料有：鸡蛋、水、杯子、盐、勺子和筷子。
Above all, prepare a cup of clear water, put the egg in clear water, the egg rises without float, my questioningly solilo-quize: "Why does the egg rise without float? " I " bang " the ground beats cerebral door, briny float egg, that should want ability having salt to be opposite! One spoon salt was joined in water of my go toing, water begins a bit muddy rise. I take a chopstick, go to saline agitate melt, put the egg into water again, egg " Dong " the ground sink a cup of bottom, lie in cup bottom motionless. I think: Why does the egg rise without float? The likelihood is salt is put too little.
首先，准备一杯清水，把鸡蛋放清水中，鸡蛋并没有浮起来，我疑惑地自言自语道：“为什么鸡蛋没有浮起来呢？”我“啪”地一拍脑门，盐水浮鸡蛋，那应该要有盐才对呀！我往水里加入了一勺盐，水开始有点混浊起来。我拿筷子，把盐搅拌到融化，再把鸡蛋放入水中，鸡蛋“咚”地一声沉入杯底，躺在杯底一动不动。我想：为什么鸡蛋没有浮起来呢？可能是盐放太少了吧。
Then I joined two spoon salt in past cup again, put an egg. I am taking a chopstick to be in agitate, the egg resembles dancing be like, go up a little while, fall a little while. Also not be in water very peace and tranquility, resembling is sweep waterspout wind, the egg shakes place, float was in among, resemble a tumbler.
接着我又往杯子里加入了两勺盐，放入鸡蛋。我拿着筷子在搅拌，鸡蛋像跳舞似，一会儿上，一会儿下。水里也不是很太平，像是刮起了水龙卷风，鸡蛋一摇一摆的，浮在了中间，像个不倒翁。
Finally, I added one spoon salt in past water again, agitate arrives deliquescent, at this moment, water had become snow-white color, resembled issueing snow same. At this moment, the egg showed a lovely small head from inside water, my agitato cries: "Succeeded, I succeeded eventually, egg float rose... "
最后，我又往水里加了一勺盐，搅拌到溶解，这时，水已经变成了雪白的颜色了，就像下过了雪一样。这时，鸡蛋从水中露出了一个可爱的小脑袋，我兴奋地大叫道：“成功了，我终于成功了，鸡蛋浮起来了……”
Why can you succeed? Because briny density is more than the density of the egg,that is, let egg float rise.
为什么会成功呢？那是因为盐水的密度大于鸡蛋的密度，让鸡蛋浮起来了。
