Slowly, egg carapace became for the most part white,
6、 this white also has depth, look carefully, seem to drawing the figure of a few beauty above, very good-looking.

10、。这是怎么回事？我确定等第二天见老师问个到底。 The experiment sums up a class to go up, whole class classmate besides the egg besides me, molten.

12、酸，所以醋酸和碳酸钙反应生成醋酸钙、二氧化碳和水。鸡蛋壳中的碳酸钙含量变少，就软掉了。 Heard the teachers explanation, everybody just suddenly be enlightened. Then the teacher tells us again, acetic egg still has a lot of magical effect!

After coming home I must again experiment. 哦，原来如此。回家后我肯定要再试验一次。(文/郑佳文)
