On October 24th, I felt that the weather was already very cold, so I watched an old Marvel movie by Ang Lee in 2003 while I was not doing experiments. After watching the movie, I wanted to stand up and walk around. Unfortunately, the laboratory was only so big, and I could only stop at the window when I walked around. Next to it, the outside of the window sill is reinforced with an anti-theft net. When the laboratory was first built, a pot of pothos was planted in the small space between the glass window and the anti-theft net. Now it has grown to cover the entire lower part of the window, and the green shiny leaves are also very beautiful. I looked around in a circle, and when I saw the details, I found a very dense spider web in the lower right corner. I poked my head in with interest to see what was going on. Thin and dense webs surrounded the entire three-dimensional space in the lower right corner of the window sill. The feeling of being so thin and dense is amazing. I wonder how much effort the owner of this spider web spent to make it so dense. Spider webs are also not very durable. If the wind blows, the webs will be completely destroyed. If it rains, the webs will no longer stick. If a leaf, a bird or some other unexpected accident happens on a sunny day, such a big project will have to be started from scratch. It's late autumn now, and there's not much harvest except some dead yellow branches and fallen leaves hanging on the Internet.
