Anyway, after reading my topic, you must have a feeling of becoming a monk-scratching your head. How can a piece of cloth not be afraid of burning? However, in my life, I have seen pieces of cloth that are not afraid of burning. Are you interested in seeing them? If you are interested, come with me!

It was a sunny Friday morning, and white clouds were floating in the blue sky of Wan Li. We are having a science class. The science teacher asked an interesting question in class: "You have seen a kind of cloth in your life, and you are not afraid of fire?" As soon as the science teacher asked questions, the class was like a frying pan, and the students talked about it in succession below. Some said, "How can there be cloth that doesn't burn?" Some said, "Of course not. Science teachers can fool others, but not me! " "Others said," if you can compile a popular science book, there should be a cloth that is not afraid of burning. "I think so, but I can't find it. I don't think so, but there is no evidence. So I'm going to go home and do an experiment to prove whether there is any cloth that is not afraid of burning.

Be prepared when you go home: a good cloth bought in Wang Hu market, a lighter and a good iron tripod. The experiment began. I put the cloth gently on the tripod first, and then carefully opened the lighter. The lighter immediately "jumped" a dazzling light, set the cloth on fire, and soon "ate" the cloth. "ah! There is no cloth that is not afraid of being scalded. It turns out that the science teacher is lying to us and treating us as three-year-olds! " I patted my forehead and suddenly realized that I was a little unhappy.

My father, who was watching TV, saw my experiment and what I said, put down the good football match and came over to me seriously and said, "What do you mean, there is no cloth that is not afraid of burning?" I'll do an experiment for you. I believe you will learn a lot and know that there are still pieces of cloth in the world that are not afraid of burning! "Say that finish, dad turned and took out a bottle of alcohol from under the bed, and took out a small bowl of tap water from the tap, and took out a piece of worn-out cloth from the closet. When I saw this scene, I whispered, "With such shabby cloth and so much wine, my father must have lost his head!" " Unexpectedly, my father heard my words and said sternly, "What's it to you? Concentrate on my experiment! " "

Dad's experiment began, as if the beautiful woman had unveiled the veil. I saw dad first pour water and alcohol together (more water, less alcohol) and mix them evenly. Then put the small piece of cloth in the water to "bathe" for a minute or two. Dad gently picked it up and put it on the tripod. Finally, the lighter lit, and the small piece of cloth was "surrounded" by the torch, but the small piece of cloth could not be taken. After a while, the small piece of cloth was "unscathed" and only a stream was exposed. "Dad, you are amazing!" I said enviously. "Nothing, it's a piece of cake!" Dad said with a smile. "But why can't this small piece of cloth burn?" I asked dad. "This ... this ... this ... I ... I don't know ... I don't know." Dad faltered, and his voice was obviously much lower than before. Like a pupil who did something wrong, he admitted his mistake in front of the teacher. "Bad dad, bad dad, bad dad ..." My mouth was tilted and I said it out loud on purpose. At this time, my mother, who was listening to my father's conversation, came over and said to us, "The reason why that cloth is not afraid of burning is because it was full of a mixture of alcohol and water." Alcohol will burn when it meets fire, but the steam' protects' the cloth and makes the flame' stay' at the steam, so the cloth can't burn. "After listening to my mother's explanation, my father and I said in unison," Oh! So that's it. "
