Afternoon, I return the home, put down satchel to begin to do a test. Today, I should do the test of the egg ” that “ can swim.
下午，我回到家，放下书包开始做实验。今天，我要做“会游泳的鸡蛋”的实验。
The experiment began. I prepared a cup first clear the water that sees an end, a packet of salt and an egg. Next, I gently end up puts an egg into water, discovered: The egg sank benthic, seem big circuit. Think in my heart: Why can the egg sink?
实验开始了。我先准备了一杯清澈见底的水，一包食盐和一个鸡蛋。然后，我把鸡蛋轻轻地竖着放进水里，发现了：鸡蛋沉到了水底，好像大了一圈。我心里想：鸡蛋为什么会沉下去呢？
Then, I pour on a few salt in ladle then, put into water, sufficient agitate, after agitate is over, I put the egg into water again, but the egg did not want the meaning that float rises at all, heavy still in benthic. My heart thinks, the egg was asleep in water!
于是，我接着在勺子里倒上一些食盐，放入水中，充分的搅拌，搅拌完之后，我又把鸡蛋放入水中，可是鸡蛋根本就没有要浮起来的意思，仍然沉在水底。我心想，鸡蛋是不是在水里睡着了呀！
Then, I am taking a packet of whole salt, lean to one side, at the same time agitate, water and salt are like statified and same, really interesting! Next, I take an egg to be put gently into water, magical thing happened, the egg was played a few times in water unexpectedly, rose with respect to float next. Too marvellous, the experiment succeeded.
接着，我拿着一整包食盐，一边倒，一边搅拌，水和盐好像分层一样，真有趣啊！然后，我拿起鸡蛋轻轻地放入水中，神奇的事情发生了，鸡蛋居然在水里弹了几下，然后就浮起来了。太棒了，实验成功了。
Finally, I just know, original, salt was joined in clear water, the density of water greatened, buoyancy also greatens accordingly, the egg came up with respect to float.
最后，我才知道，原来，在清水中加入了食盐，水的密度变大了，浮力也跟着变大，鸡蛋就浮上来了。
This is interesting experiment really!
这真是一次有趣的实验啊！(文/朱子奕)
