Today, I heard my father say that the seeds in the pepper we bought were actually green. I also felt very strange, so I found out a few red pepper seeds and put them in the water. Some red pepper seeds were found to float upwards, and some were sinking. The same is true for putting green pepper seeds in.

I asked Dad what is the difference between the two? Dad also said that he didn't know. He thought that the green pepper seeds were people who didn't know what to put in when they peppered them.

These are all I don't understand. I have to read more books to understand the secrets of nature!
