Magical fat sea

On Wednesday night, Teacher Sun said in the QQ group: "Buy a fat sea tonight, and bring it to the school tomorrow in a school bag." My mother saw the notice, and when she came back from work, she bought me a few fat seas, I first observed them, took two of them and soaked them in hot water, and drank water. Put the remaining one in the bag. The next morning, I got up early and took my bag and lunch box and walked to school, and when we got to school, we started reading early and then ate breakfast. At this time, Teacher Sun came, and I wondered in my heart: Teacher Sun came, so in this lesson, Teacher Sun would not tell me about the fat sea. The class bell thought about it, Teacher Sun did not go, and sure enough, this lesson was given to us by Teacher Sun. Teacher Sun ordered us: "All students, now you take out your fat sea and observe it to see how it is." Hearing the teacher's order, we all quickly took it out to look at it, and I took a closer look, and its two ends were pointed, and in the middle were big and fat, and there were wrinkles like old people's lengths. The fat sea was round, like a rugby ball, and the color was black brown. I wondered, "Where did it grow?" What's the value? Is it toxic? Is it nuts? Teacher Sun continued to order: "Now you take the fat sea and smell it, and see what it smells." I took it and sniffed it, and there was a faint smell of Chinese medicine, and I liked the smell very much. Teacher Sun then said, "Now you all take a bite out of your fat sea and see what it feels like." I put it in my mouth and bit it, its shell is hard and the inside is soft. "Click", it turned out to be the shell of the fat sea cracked! I immediately felt bitterness in my mouth, which should be the Chinese medicine taste of the fat sea. Teacher Sun continued: "Now everyone takes the fat sea to soak in water and see how it will change." Some students went to the water dispenser to pick up hot water, some students did the seat with a water cup, waiting for Teacher Sun to pour hot water into their water cup, after having hot water, I threw the fat sea into the cup, and then began to observe what kind of changes would happen to the fat sea, a moment the shell of the fat sea cracked, slowly, slowly, the fat sea became bigger and bigger. Teacher Sun said: "Now you carefully observe what has happened in the fat sea, how many times have happened." So I found that my fat sea had become a cute leaf for the first time, a kitten's paws were very large for the second time, and after a while, my hot water was all absorbed by the fat sea, and I added some more water to the cup, and it became a sofa for the third time. Teacher Sun continued to say to us: "Now you take your own fat sea water and drink it to see what it tastes like." I took the cup and tasted it, not crying or sweet, but also with a faint smell of Chinese medicine, which I liked very much. Teacher Sun finally issued an order to us: "Now you can play with your own fat sea and touch it to see what it feels like." I held the fat sea and touched it and I felt it as soft as SpongeBob SquarePants, like jelly and like jelly, and I didn't want to play when I played. I thought I crushed it and threw it in the trash, I squeezed it with my hand, and sure enough, it broke, but there was a hard thing, I took it out and looked at it, it turned out to be a child of the fat sea! At this time, Teacher Sun told us: "Although the fat sea has its medicinal value, but we can not blindly eat, the first lesson to moisten the throat, very suitable for people who talk more to eat, the second drink will hurt the kidneys, should not drink more." This is really a magical fat sea.....
