有一天上午，哥哥带我出去玩。这时，我觉得自己口渴了，我对哥哥说：“哥哥，我口渴了，你能给我买瓶可乐吗？”哥哥同意了，去超市给我买了一瓶可乐。我喝了一口，然后继续走路。我一边走一边把可乐摇啊摇。不一会儿，我又觉得自己口渴了，我打开盖子，哇！可乐怎么飞起来了？直往外冒气泡。我心中马上出现了一个大大的问号。我问哥哥：“哥哥，可乐为什么摇啊摇，可乐泡泡就会往上冒呢？”哥哥说：“我又不是科学家，怎么可能知道。”我瘪着嘴说：“你不是科学家，但你都已经上大学了，怎么这样的问题都不知道。”
One morning, my brother took me out to play. At this moment, I felt thirsty and said to my brother, '; Brother, I'm thirsty. Can you buy me a bottle of cola? ” My brother agreed and went to the supermarket to buy me a bottle of cola. I took a sip and then continued walking. I shook my cola while walking. After a while, I felt thirsty again and opened the lid. Wow! Why did Coke fly? Bubbles are rising straight out. A big question mark immediately appeared in my heart. I asked my brother: '; Brother, why does shaking cola cause bubbles to pop up? ” My brother said, '; I'm not a scientist, how could I possibly know. ” I pouted and said, '; You're not a scientist, but you're already in college, so why don't you know such a question. ”作文网 zUOwEnBa.Net
回到了家，我又去问百度，百度说：“可乐里有很多的二氧化碳，所以只要摇啊摇，二氧化碳冒出来，可乐就会喷出。”我又把水装进瓶子摇啊摇，看看能不能喷出来。可是我试了上千万次就是喷不出来。果然是可乐里的二氧化碳在作怪。
When I got home, I asked Baidu again, and Baidu said:; There is a lot of carbon dioxide in cola, so as long as you shake it, the carbon dioxide will come out and the cola will spray out. ” I put the water in the bottle again and shook it to see if it could spray out. But I tried millions of times but couldn't spray it out. It is indeed the carbon dioxide in the cola that is causing trouble.
我又知道了一个科学知识。
I have learned another piece of scientific knowledge.
