My discovery

My discovery

Once, our whole family ate a reunion dinner.

When we were eating fish, the younger brother accidentally let the fishbone get stuck, and it was really uncomfortable to look at her. We quickly sent the younger brother to the hospital. The doctor in the hospital took the fishbone with vinegar. I thought to myself: How can I take out the fishbone with vinegar? This question makes me puzzled. So at night, after eating dinner, I poured a large bowl of vinegar, and found a big fishbone in it. See what happens. After waiting for an hour, I went to see that the fishbone became softer and thinner. By the next morning, I saw the fishbone in the bowl, which turned out to be magical and disappeared.

I finally got it, why the vinegar can take out the fishbone. Because in a short time, vinegar can soften the fishbone.
