今天,我在课外书上看到一个有趣的实验———蛋壳变软。鸡蛋壳天生硬邦邦的,怎么会变软呢?作者是不是在故弄玄虚?我决定亲自动手做这个实验。我按照书中的描述,准备了以下材料:大米、鸡蛋、醋和一只碗。接着,我把鸡蛋放入碗里,再用大米把鸡蛋埋起来,最后,往碗里倒入醋,直到大米全部被淹没为止。 Today, I read an interesting experiment in my extra-curricular book - the shell softens. Egg shells are stiff, how could it soften? The author is not in the trick? I decided to personally do this experiment. According to the book, I prepared the following materials: rice, eggs, vinegar and a bowl. Next, I put the eggs into the bowl, buried the eggs with rice, and finally poured the vinegar into the bowl until all the rice was submerged.
