When I got home, I saw that the coke my mother bought was a little greedy, so I dawdled around. When my mother saw it, she smiled and said, Silly girl, open it if you want! There are so many cokes that you can't burn them all.
I listened, and quickly went to twist the coke bottle cap. However, I tried to twist it with my hands and bite it with my teeth, but the bottle cap wouldn't move.
Mom said: Maybe your hands are too wet. Try to dry them. So I dried my hands and tried again, but it still didn't work.
Mom asked me to put on a rag again. I tried it and the bottle cap unscrewed. What is the reason?
I went through the books, searched and searched, and finally found the answer. Originally, my hands were too wet, and then I screwed the bottle cap, and the friction became smaller. Put a rag on it, the friction will increase, and the bottle cap will be unscrewed easily. In other words, the greater the friction, the easier it is to open the bottle cap, so there will be stripes on the lid of the beverage bottle.
It seems that there are a lot of science around us!

After a lot of hard work, I finally finished washing the dishes. I put them in the cupboard. Then, wash the dishes, and I'll wash chopsticks. Wash the chopsticks.

The sun is like a rolling golden ball, which soon rolls from the east to the west.
At this time, the sun put away its dazzling light, and the whole body was golden yellow, just like a golden disc. After a while, the golden disc is half gold and half red. Like a colorful little round bubble. Baiyun was also fascinated by the color of the sun, and involuntarily imitated the sun and became the same color as the sun.
Slowly, the sun all turned red, red, like a flaming fireball. The original group of followers turned red. I think the clouds are like a follower. The sun turns into what color.
Gradually, the sun hides here and there, acting like a shy little girl. Finally, he got tired of playing and went down to sleep before he could say hello to his companions.
Although the sun has gone, its afterglow is still in the sky! And I am still intoxicated by its beauty.
