Have a problem the result that I think to know it all the time, even if is the person that won't swim also can easily float is on the Dead Sea. I examined a data, because seawater contains sea salt of tall pH indicator,understanding that is, briny flotage is on several times bigger than the flotage of clear water, so the person won't sink.
有一个问题我一直想知道它的答案，即便是不会游泳的人也能够很轻松地浮在死海上。我查了资料，了解到那是因为海水含高浓度的海盐，盐水的浮力比清水的浮力大上好几倍，所以人不会下沉。
Classes are over one day return the home, I see there is —— of a book on the desk " love science as a child " my too impatient to wait was opened among them, the name of this book cries " , , power is great " .
有一天放学回到家，我看到写字台上放着一套书——《从小爱科学》我迫不及待打开了其中一本，这本书的名字叫《哗啦，哗啦，力量大》。
Say to put an egg in float of the egg in clear water not to come up on the book, but put the egg in brine,the egg can come on float. Although be told in that way on the book, but I am not believed all the time. “ ear listens for empty, the eye sees for solid ” , I carry a clear water, took a bag of salt, took a few eggs, began my test. I put the egg in the tub that has clear water composition first, the egg is heavy it is by the basin, I begin to go to salt was scattered a few minutes to go in the basin the egg comes up without float, thinking in my heart is an egg probably cannot come on float again very much. Suddenly a term comes out from the flash in my brain ——“ Gao Nong spends ” . The much salt that drop a point retries try, I poured half bags of salt again, with the chopstick slowly agitate. Crossed one small conference, “ miracle ” appeared really, each rose to the egg surface, I am very excited at that time, the experiment succeeded. I withstand with the chopstick the egg presses it toward basin bottom do not let his float come up, but the egg is not obedient, want a chopstick to leave only, just press the egg that go down to come up with respect to meeting float seem to be mixed intentionally my oppose, I am extremely glad.
书上说把一个鸡蛋放在清水里鸡蛋浮不上来，可是把鸡蛋放在盐水里鸡蛋就可以浮上来。虽然书上那样讲，可我一直不信。“耳听为虚，眼见为实”，我端来一盆清水，拿了一袋盐，拿了几个鸡蛋，开始了我的实验。我先把鸡蛋放在有清水作文的盆里，鸡蛋沉在盆底，我开始往盆里撒盐几分钟过去了鸡蛋没有浮上来，我心里想大概是鸡蛋很重不能浮上来吧。突然一个词语从我脑子里闪现出来——“高浓度”。多撒点盐再试试，我又倒了半袋盐，用筷子慢慢搅拌。过了一小会儿，“奇迹”真的出现了，鸡蛋一个个浮出了水面，我当时很激动，实验成功了。我用筷子顶住鸡蛋把它往盆底压不让他浮上来，可是鸡蛋就是不听话，只要筷子一离开，刚刚压下去的鸡蛋就会浮上来好像成心和我作对，我高兴极了。
Briny density is big, buoyancy nature is big also, I did this test personally today, test and verify this truth, I discover ” for this my “ and feel proud.
盐水的密度大，浮力自然也就大，今天我亲自做了这个实验，验证了这个道理，我为我的这个“发现”而感到自豪。(文/梁楠)
