Eggs are floating!

——Remember an interesting experiment

Nanchang Donghu Primary School third grade (4) Ban Ding Yuchen

On Saturday's composition class, Teacher Wang made us an interesting Small experiment.

The experiment began. I saw that Mr. Wang had magically removed a bottle of pure water from the podium, a glass with a dishcloth and a bag of salt. Teacher Wang first took out the dish cloth in the glass, carefully placed it on the palm of his hand and spread it out. I was bright in front of my eyes, and there was an egg hidden inside! Then, Teacher Wang picked up the pure water, unscrewed the cap, and poured the water into the glass until the water level reached two-thirds of the height of the cup. Teacher Wang gently picked up the eggs, carefully placed the eggs in the water, and the eggs sank directly. Teacher Wang took out the eggs, held the glass, poured some salt into the cup, and then quickly stirred the water with a thin, long chopstick until the water became grayish. At this time, Teacher Wang gently put the eggs into the salt water, and the eggs bounced a few times in the salt water, gradually sinking into the bottom of the water. At this time, a classmate stood up and said: "" must be less salt! "

What an interesting experiment, I have to do this experiment myself!
