The wonderful use of balloons, prompt: What problems did Xiaodong find when drying clothes?

Hello, landlord, I'm glad to answer your question.

Today, the weather is sunny. Xiao Ning helps her mother dry clothes. He hung his clothes on a bamboo pole, and the rope on the bamboo pole suddenly changed from straight to curved. Xiao Ning was stunned, and his clothes were about to fall and get dirty. Xiao Ning stood there, feeling at a loss, thinking: If only something kept holding on to the rope. Xiao Ning suddenly heard a burst of firecrackers. When she saw Ningning Store open at the door, colorful hydrogen balloons held high the striking slogan of good luck, which was very clear. Xiao Ning had a brainwave and thought, Why don't I tie the hydrogen balloon to the rope and straighten it? Without saying anything, he ran to the grocery store and bought three big round hydrogen balloons. He came to the bamboo pole and tied the three hydrogen balloons tightly to the rope. The rope gradually straightened and changed from arc to straight line. Clothes hangers seem to have a colorful crown, and they seem to have life. When it blows, the hanger shakes, as if to say, "thank you, Xiao." On the other hand, Xiao Ning shouted happily. He clapped his hands while dancing. He smiled, and the smile on his face was like a beautiful flower that just opened.

Through this incident, Xiao Ning understood that four points should be paid attention to when doing things: careful observation; Find the problem; Ask questions; Solve the problem. He also learned that there are sciences everywhere around him, but not everyone will find them. They only belong to those who are good at observing, discovering, proposing and solving them.
