Today, my grandma and I exercise in the gym. It's time to go after exercise. Suddenly my grandmother met an old friend and asked me to wait for a while. When my feet were walking around, I walked out of the door and enjoyed the lotus leaves.

The little brother next to him poured water on the lotus leaf, and the bottle was used to hold drinks. I looked into the lotus leaf, and the water was gone. Is it bad or something? Did you come out? No, no, no, that's impossible. Lotus leaves are like bowls that we eat. There must be a mystery. So I went home to find the mystery, asked my mother, she certainly wouldn't, and asked my father, who said he didn't know. You are on your own.

I went into Xinhua Bookstore to find the mystery. I opened all the books about science, but there was no information about lotus leaves. Gee, why didn't I think of that! computer.

I hurried home and turned on the computer to inquire about this mystery. Ah, I finally found that the leaves of the lotus leaf are covered with "hills", and the "hills" are covered with fluff, like dense vegetation on the mountain. At the top of the "mountain bag", there is a "bunker" that is as convex as steamed bread. Therefore, the depression of "Shanbao" is filled with air, thus forming an extremely thin air layer with only nanometer level on the tight leaf surface. Because rain and dust are like giants to these microstructures on the lotus leaf, it is these tiny dual structures that make the contact surface between the lotus leaf surface and water droplets or dust very limited. Therefore, the phenomenon that water drops roll on the leaves and take away dust is produced.

After this investigation, I understand this truth and tell us that there are many similar phenomena in our lives, which need our brains, understanding, observing and discovering. The mystery of fantasy is waiting for you to discover.
