One experiment

A cup has nothing to do with an egg, but with water and salt there is a little secret.

On Sunday morning, the home was cut off, and the house was cold and clear, and I couldn’t watch TV. Playing computer is too boring, so I started an experiment in the strong sunshine. I took a bare egg in the freezer, took a cup full of water in the kitchen, prepared the things, and I started experimenting. I put the egg gently into the cup filled with water. I watched quietly, the egg kept floating on the cup, and I thought I could let the eggs in the water sink to the bottom of the water? I thought about it with my smart head, and while I was thinking about turning around in the kitchen, I glanced at the seasoning with my eyes. In a blink of an eye, a bag of edible salt appeared in front of my eyes. "Hey! Salt has weight. I can put the salt in the water and make the egg sink." I said to myself. After that, I picked up a bag of edible salt and put a few spoonfuls in the water. I concentrated my eyes on the cup, and I saw that the "disobedient" egg finally sank to the bottom of the cup. Dad is back, I told my father a brainstorming surprise, he praised me for being smart.

In fact, science is around you and me. As long as you observe it carefully, you will find a lot of happiness and secrets!
