Xiaotong thought that the jar was not good, and it was the most unpalatable thing in the world! Xiao Tong did not understand why her sister and dad were interested in the jar. He kindly wanted to stop her sister from touching this terrible thing in the past.

But Murphy thought he was going to make trouble, so he hugged him in his arms and did n’t let him move. The little guy struggled “umm” and wanted to escape his mother ’s bondage.

No! Let me go, I'm going to save my sister!

"Wow!" Suddenly, Xiao Luo's ear heard excited cheers from his sister. He stopped in doubt, raised his head, and looked over.

Of course, Xiaojiao will not pay attention to the details, he just saw his sister and dad looking around the big bottle.

If it is a cartoon, there should be a lot of question marks floating on the little guy ’s head at this moment: What happened? Why is my sister so excited?

Xiao Liao did not see it. At this time, the eggs in the glass bottle had already floated up and down in some white water. Although it is only suspended in water, this change is enough to make Xi Xi cry in surprise.

"Baba, the eggs are floating!" Xi Xi turned her head and reported excitedly to her father.

"It hasn't completely floated up yet, you can try adding more salt." Yang Yi encouraged Xi Xi to finish the experiment.

Of course, there is no need to go into details in the following experiments. It is nothing more than adding more salt to let the eggs rise to the surface.

Xixi is more curious, what is the magic power to let the eggs float out of the water?

No, after growing up, I have n’t asked why Xi Xi for a long time, and today I asked my dad again with interest: "Baba, why is this happening?"

This scientific principle is not difficult to explain, but the difficulty is how to explain it to Xi Xi to understand clearly, Xi Xi now does not understand what is called buoyancy, what is called specific gravity or density.

So, Yang Yi pondered it and said, "Xixi, do you think the water is heavy, or the eggs are heavier?"

Xi Xi tilted her small head and thought for a while, but finally chose water.

"Because it is heavy, I can take it hard!" Xi Xi pointed to the glass bottle with water and said seriously, "However, eggs are easy to handle!"

Yang Yi understood his loophole, so he took two identical cups and eggs and began to demonstrate.

"Look, I put eggs in one cup and add water to one cup, but the volume of water I add is about the size of an egg." Yang Yi smiled and handed two cups to Xixi, "You are now Look again, which one is heavier? "

However, the difference in weight is still very small. Xi Xi measured it, but still couldn't measure it.

Yang Yi had to go to the small electronic scale used to weigh the dishes in the kitchen, compare the weight data of the two, and Xi Xi finally got the answer.

"Now do you think the water is heavier or the eggs are heavier?" Yang Yi asked with a smile.

"Eggs are heavy!" Xixi responded quickly, keeping up with his father's thinking speed.

"In addition, do you think the iron blocks of the same size are heavier? Or the wood of the same size is heavier?" Yang Yi said.

Xixi does not need to do experiments, but also knows how to answer this question, only to hear her clear response: "Iron is heavier!"

"That's right, under the premise of the same size, iron blocks are heavier than wood and eggs are heavier than water. We call it heavier because of its density!" Yang Yi still uses iron blocks As an analogy with wood, "meaning that it is stuffed with more and heavier things in its small body."

Xi Xi nodded, seemingly incomprehensible.

It's really difficult to explain, but Yang Yi feels that if he talks more, Xi Xi will learn more in a subtle way, and will be able to understand some of his scientific knowledge later.

"Well, this dense egg can sink to the bottom of the water because it is heavier than water, do you say it?" Yang Yi said with a smile.

This Xixi can understand that the little girl nodded her head seriously.

"Then we add salt to the water, the salt will be incorporated into the water, so that when we drink salt water, we will feel the salty taste." Yang Yi made a relatively fresh analogy, "It is like , We are carrying a school bag with stuff, and now we have to unzip it and continue stuffing it in, so that it will become heavier? "

"Yes!" Xi Xi continued to nod.

"So why is that?" Yang Yi smiled and asked Xixi a small question.

"Because, because ..." Xi Xi still didn't understand. At this moment, she was confused again in the face of her father's problems.

Murphy listened with interest, and when she saw Xi Xi said she understood, and then opened her mouth again, she couldn't help but said, "Did your father just say it? Because of its density It ’s getting bigger, so it ’s getting heavier too! ”

Yang Yi smiled and said: "It doesn't matter, we now understand that after adding salt, the brine will be heavier than the water!"

"I know, I know, because it has salt!" Xi Xi said aggressively now.

"Yes, if you continue to add salt, it will become heavier!" Yang Yi does not intend to talk about the concept of more esoteric solubility for the time being, just saying, "Because the salt water becomes heavier, when it is more heavy than eggs When heavier, will the lighter eggs float? "

Xi Xi listened to her, and did not know if she really understood it. Anyway, she nodded energetically.

"Let ’s apply today ’s findings to see if we can apply them to a wider range of examples!" Yang Yi laughed. "For example, do you think swimming in the sea water, like in summer, when we go to the coastal area Like playing at the beach, is it easier to float in the water than swimming in our freshwater swimming pool? "

Where does Xixi remember these two feelings? However, although she couldn't compare which of the two swimmers was easier to float, Xixi still understood what Dad had to say.

I saw the little girl giggling and said happily: "I know, I know, because the sea water is also salty! There is salt!"

"Yes!" Yang Yi gave her thumbs up in praise.

"Baba Baba, Baba Baba, let's play another experiment! It's so interesting!" Xi Xi and his dad cried out again after they had finished these principles.

There must be a lot of interesting content in such a big book!

Xi Xi smiled with excitement, and Xiao Jiao looked at him sideways. He can't understand these reasons, but the little guy feels that his sister smiles so happy, there must be something very fun, his small eyes are full of envy and expectation.

I really want to play with my sister!

......

The filming of "Remaining Sin" has been going on for more than a month. Recently, the crew went south and went to Yangcheng to shoot some local scenes. Guo Ziyi, who plays an important supporting role, also followed.

However, the weather suddenly became colder, and the news report also said that it was cold air that has not been encountered for ten years, which made Tan Huizhen worry about whether Guo Ziyi in Yangcheng in the south would be frozen.

Is n’t there a popular saying on the Internet now: I am a wolf from the north, but I became a husky in the south?

Although this is a joke, it still makes sense!

The cold in winter in Guangdong Province is wet and cold. Although the temperature looks very high, the air with high humidity will make this cold like an anthrax of the bones. !

So, when Tan Huizhen called Guo Ziyi, he suddenly asked where is Guo Ziyi's agent now?

"You ask what Ding Xiang is doing?" Guo Ziyi was alert. "She is in Jiangcheng! She still has schoolwork. It is impossible to run around with me before graduation."

At this moment, Ding Xiang, who was sitting next to Guo Ziyi, straightened his waist nervously and sat staring at Guo Ziyi.
