Argumentative paper on snail's insistence on climbing the wall. Urgent!

After the rain, the sky was much brighter and the ground was still wet. Hey, there is a small snail on the wall. I walked in, and it was a small snail. When I took off the snail, I was curious. Why do snails climb walls, but we humans can't walk on them? With this question, I caught another snail and prepared to carefully observe its every move.

I caught a snail and put it in a plastic plate. At this time, the snail slowly emerged from its "small house". Alas, the snail's tentacles are long and short for a while, which is really naughty! Suddenly, the snail got up slowly, and I watched it carefully. Suddenly, I came across something sticky on the snail's crawling route. So, I looked at it carefully, and it was mucus. What's the relationship between mucus and snails? It suddenly occurred to me that snails climb on the wall by viscosity?

So, I put the plastic board on it, and sure enough, snails can crawl on the plastic board and release mucus at the same time. In order to further confirm my unexpected discovery, I ran to ask grandpa. Grandpa's answer is the same as I expected. Snails secrete mucus when they crawl, which is the way snails crawl on walls.

Knowing this knowledge, I am really amazed at the infinite mystery of nature. However, there are more amazing stories in the scientific community. As long as we pay attention to everything around us, we will find knowledge that we never knew before. Go ahead, the magic of the scientific world is waiting for us to discover!
