中午,妈妈正忙着做菜,让我拿咸鸡蛋来煮,我连忙跑到咸鸡蛋缸边,使劲地伸手去捞,心里想鸡蛋一定沉在最下面,我得用劲向下摸。可是摸来摸去下面一个也没有。又仔细一摸发现蛋都浮在了水上面。这时我感到很奇怪,平时蛋放在水里,都是沉在下面的,可这次鸡蛋在盐水里为什么浮起来了呢 At noon, my mother is busy cooking, let me take salty eggs to cook, I quickly ran salty egg cylinder edge, hard to reach out fishing, my heart would like to sink eggs in the bottom, I have to work hard to touch. However, no one touched the following. Again carefully found eggs floating in the water above. At this moment, I feel very strange. Usually, the eggs are placed in the water, all sinking below, but why did the egg float in the salt water?
