神奇科学小实验作文醋泡鸡蛋英文回答:
Vinegar-Soaked Egg: A Magical Science Experiment.
Have you ever wondered how vinegar can transform a regular egg into a bouncy, rubbery egg? Well, let me tell you all about this magical science experiment!
First, gather all the materials you will need: a raw egg, a glass or jar, and some vinegar. Make sure the glass or jar is big enough to fully submerge the egg.
Now, carefully place the egg into the glass or jar. Then, pour enough vinegar into the glass or jar to completely cover the egg. It's important to note that the vinegar should be white distilled vinegar, as it contains acetic acid, which is key to the experiment.
Next, let the egg soak in the vinegar for at least 24
hours. During this time, the vinegar will start to dissolve the eggshell. You may notice bubbles forming around the egg, which is a sign that a chemical reaction is taking place.
After 24 hours, carefully remove the egg from the vinegar. You will notice that the eggshell has become soft and rubbery, and can even be easily peeled off. This is because the acetic acid in the vinegar has reacted with the calcium carbonate in the eggshell, breaking it down.
Now, here comes the fun part! Hold the egg a few inches above a table or hard surface, and gently drop it. Instead
of cracking like a regular egg, it will bounce! This happens because the egg has become more elastic due to the removal of the shell. It's like a magic trick!

醋泡鸡蛋,一个神奇的科学实验。
你是否曾经想过为什么醋可以将普通的鸡蛋变成有弹性的鸡蛋呢?好吧,让我告诉你关于这个神奇的科学实验的一切!
首先,收集你需要的所有材料,一个生鸡蛋,一个玻璃杯或罐子,以及一些醋。确保玻璃杯或罐子足够大,可以完全浸泡鸡蛋。
现在,小心地将鸡蛋放入玻璃杯或罐子中。然后,倒入足够的醋,完全覆盖鸡蛋。需要注意的是,醋应该是白醋,因为它含有乙酸,这是实验的关键。
接下来,让鸡蛋在醋中浸泡至少24小时。在这段时间里,醋将开始溶解鸡蛋壳。你可能会注意到鸡蛋周围出现气泡,这是化学反应正在发生的迹象。
24小时后,小心地将鸡蛋从醋中取出。你会注意到鸡蛋壳变得柔软而有弹性,甚至可以轻松剥离。这是因为醋中的乙酸与鸡蛋壳中的碳酸钙发生反应,将其分解。
现在,来了有趣的部分!将鸡蛋在离桌面或硬表面几英寸的高度上握住,然后轻轻地放下。它不会像普通的鸡蛋一样破裂,而是会弹起!这是因为鸡蛋由于去壳而变得更有弹性。就像一个魔术一样!
