The Interesting Experiment: The Fountain in a Bottle.
One day, I conducted an interesting experiment called "The Fountain in a Bottle". I gathered all the materials I needed, which included a plastic bottle, a balloon, baking soda, vinegar, and a funnel.
To begin the experiment, I first poured vinegar into the plastic bottle using the funnel. Then, I used the funnel again to add baking soda into the balloon. I carefully attached the balloon to the opening of the bottle, making sure it was tightly sealed.
Now, it was time to observe the magic happen! I lifted the balloon, causing the baking soda to fall into the vinegar inside the bottle. As soon as the two substances mixed, a chemical reaction occurred. This reaction produced carbon dioxide gas, which inflated the balloon.
time in a bottle The most fascinating part was when the balloon became too big for the bottle, it popped off with a loud sound. At the same time, the carbon dioxide gas escaped from the bottle, creating a beautiful fountain effect. The liquid inside the bottle shot up in a column, resembling a miniature fountain.
I repeated the experiment a few times, each time using different amounts of vinegar and baking soda. It was interesting to observe how the size of the balloon and the height of the fountain varied based on the quantities used.

这是一个有趣的实验，名为“瓶中喷泉”。我收集了所需的材料，包括一个塑料瓶、一个气球、小苏打粉、醋和一个漏斗。
开始实验时，我先用漏斗将醋倒入塑料瓶中。然后，我再次使用漏斗将小苏打粉倒入气球中。我小心地将气球紧密地封在瓶口上。
现在，是时候观察神奇的事情发生了！我抬起气球，使小苏打粉落入瓶中的醋中。当两种
物质混合时，发生了化学反应。这个反应产生了二氧化碳气体，使气球膨胀起来。
最有趣的部分是当气球变得太大而无法适应瓶子时，它会发出巨大的声音弹了出来。与此同时，二氧化碳气体从瓶子中逸出，形成了一个美丽的喷泉效果。瓶子里的液体像一个小型喷泉一样向上喷射。
我重复了几次实验，每次使用不同数量的醋和小苏打粉。有趣的是观察到，根据使用的数量，气球的大小和喷泉的高度会发生变化。
