My discovery

On Sunday afternoon, I did a small experiment.

Prepare two transparent glasses first. Then, inside the two glasses, one is filled with clear water, the other is filled with salt water with a lot of salt, and the salt water is mixed well with chopsticks. Then put two raw eggs in the water of two cups at the same time. At this time, I found that the eggs in the cup of Shengshui are calm, and the eggs in the salt water cup are floating. Why?

I checked it on the computer. It turned out to be a phenomenon of high density of salt water. For example: ten pounds of cotton is as heavy as ten pounds of iron, but you put the ten pounds of cotton in the water forever floating, ten kilograms of iron is just the opposite, and it will sink in the water. Another example: between Israel and Jordan, there is a Dead Sea, an inland salt lake. There is no living thing in the Dead Sea. Because the small fish can't sink in the Dead Sea, they die on the sea. People can't sink because they are lying on it... very fun!

This small scientific experiment made me gain a lot!
