After the heavy rain on Sunday, I was playing in the community. On the way I played, I found a snail. Its shell has a spiral shape, one centimeter in length, full body flesh, and a pair of straight tentacles on the head. I want to take it home.
Back home, I put the snail in a clean box. Looking at it so slowly, I want to test it. So I took a spoonful of salt with a spoon and thought: You must stand the test! I sprinkled some salt on it, and sure enough, it didn't escape my "devil-like torture." The snail is still walking slowly, like a grandfather. But I carefully observed the snail. Suddenly I found it a few times shorter than the original. I thought: Is the snail melted when it touches the salt? I went to ask my father and mother, and they didn't know it. "What should I do?" I sat in a chair with a sullen mood, suddenly remembered the computer, and my eyes lit up, "With!"
I finally found out on the computer why the snail melted when it touched the salt. This is not a real melt, because ninety-eight percent of the snails are made up of water, which makes it quickly dehydrated and looks like it melts.
I finally opened this secret!
I continued to observe the snail. After it recovered its original shape, I was curious about its tentacles. I used a small wooden stick to move it, and the tentacles came back at once. I thought to myself: Is the sensitivity of the tentacles very good? I checked it, and as expected, the snail's tentacles are really notoriously sensitive!
In this way, I also learned a secret of the snail through observation.
