Chapter 966

Little mango thought that the jar was not good, and it was the worst thing in the world! Xiaomi didn't understand why his sister and father were interested in the jar. He was kind and wanted to stop his sister from touching this terrible thing.

But Murphy thought that he was going to make trouble, so he held him in his arms and didn't let him move. The little guy struggled to escape his mother's bondage.

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

"Wow All of a sudden, Xiaozhuo's ear heard her sister's excited cheers. He stopped doubtfully, raised his head and looked at the past.

Of course, he didn't notice the details. He just saw his sister and father looking around the big bottle.

If it's a cartoon, there should have been a lot of question marks on the little guy's head at the moment: what happened? Why is sister so excited?

Little mango didn't see it. At this time, the eggs in the glass bottle had already floated in some muddy white water. Although it was only suspended in the water, the change was enough to make Xi Xi cry out in surprise.

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

"It's not completely floating. Try adding some more salt." Yang Yi encouraged Xi Xi to finish the experiment.

Of course, there is no need to repeat the later experiments. It is just adding more salt to make the eggs surface.

What Xi Xi Xi was more curious about was the magic power that made the eggs float out of the water?

This is not, after growing up some, for a long time did not ask why Xi Xi Xi, today again interested to ask his father: "Baba, why is it like this?"

This scientific principle is not difficult to explain. The difficult thing is how to explain it so that Xixi can understand it. Now Xixi doesn't understand what buoyancy is, what is specific gravity or density.

So, Yang Yi pondered for a while, first said: "Xi Xi, do you think the water is heavier, or is the egg heavier?"

Xi Xi tilted her small head to think about it, but finally chose water.

"Because it's so heavy, it's hard for me to lift it!" Xi Xi pointed to the glass bottle containing water and said seriously, "but the eggs are easy to take!"

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

"You see, I put eggs in one cup and water in another, but the water I added is about the size of an egg." Yang Yi smiles and hands the two cups to Xi Xi Xi, "now you have a look, which is heavier?"

However, the weight difference is still very small, Xi Xi weighed it for a while, or could not weigh it out.

Yang Yi had no choice but to ask the small electronic scale used to weigh the dishes in the kitchen and compare the weight data of the two. Xi Xi finally had the answer.

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

"The egg is heavy!" Xi Xi reaction is very fast, keep up with father's thinking speed.

"Besides, do you think iron of the same size is heavier? Or is wood the same size heavier? " Yang Yi said.

Xi Xi doesn't have to do experiments, but also knows how to answer this question. She only hears her clear response: "iron is heavier!"

"That's right. On the premise of the same size, iron is heavier than wood, and eggs are heavier than water. We call the reason why it is heavier because it is denser." Yang Yi still uses iron and wood as a metaphor, "which means that more and heavier things are stuffed into its small body."

Xi Xi nodded.

It's not easy to explain, but Yang Yi thinks that if she speaks more, Xixi will learn more and understand her own scientific knowledge more.

"Well, this dense egg can sink to the bottom because it is heavier than water, don't you think?" Yang Yi said with a smile.

This Xi Xi can understand, the little girl a face seriously ordered a little head.

"Let's add salt to the water, and the salt will melt into the water, so that when we drink salt water, we will feel the salty taste." Yang Yi made a relatively new metaphor, "it's like, we're carrying a schoolbag with things on our back. Now we have to open the zipper and continue to stuff in it. Will it become heavier?"

"Yes Xi Xi continued to nod.

"Then why?" Yang Yi smiles and asks Xi Xi a small question.

"Because, because..." Xi Xi did not really understand, at this time, in the face of her father's problem, she was confused again.

Murphy listened with great interest. Seeing Xi Xi Xi saying that she understood and could not answer with her mouth open, she couldn't help saying, "didn't your father say that just now? It's because it's getting denser, so it's getting heavier. "

Yang Yi laughed and said, "it doesn't matter. We now understand that after adding salt, salt water will be heavier than water!"

"I know, I know, because it has salt!" At this moment, Xi Xi said actively."Yes, if you keep adding salt, it will get heavier too!" Yang Yi is not going to talk about the more profound concept of solubility, just said, "because the salt water becomes heavier, when it is heavier than eggs, will the light eggs float?"

Xi Xi listened to her eyebrows and danced. She didn't know if she really understood. Anyway, she nodded her head.

"Let's take today's findings and see if they can be applied to a wider range of examples." Yang Yi said with a smile, "for example, do you think that swimming in the sea, such as in summer, when we go to the seaside in the coastal area, is it easier to float in the water than to swim in our fresh water swimming pool?"

Where does Xixi remember these two feelings? However, although she could not compare the two swimming which was easier to float, Xixi understood what her father wanted to say.

The little girl laughed and said happily, "I know, I know, because the sea water is also salty! There is salt in it

"Yes Yang Yi gave a thumbs up praise.

"Baba, Baba, let's play other experiments! How interesting Xi Xi waited for her father to finish speaking these great truths, and then she couldn't wait to cry.

Such a big book, there must be a lot of interesting content!

Xi Xi was smiling, and she was looking at it eagerly. He can't understand these reasons, but the little guy thinks that his sister's smile is so happy, there must be something very interesting. His little eyes are full of envy and expectation.

I really want to play with my sister!

……

It has been more than a month since the filming of "Yu sin". Recently, the crew went south to shoot some local scenes in Yangcheng. As an important supporting role, Guo Ziyi also followed.

However, the weather suddenly turned cold, and news reports said it was the cold air that had not happened in 10 years. Tan Huizhen began to worry about whether Guo Ziyi in Yangcheng, farther south, would be frozen.

Isn't there a popular saying on the Internet now: I'm a wolf from the north, but I'm a husky in the south?

Although this is a joke, but there is a certain truth!

The cold in winter in Guangdong Province is wet and cold. Although the temperature looks very high, the air with high humidity will make it as cold as gangrene attached to bones. It seems that the cold air is going to drill into the bone according to the Yin measurement!

As a result, Tan Huizhen called Guo Ziyi, and suddenly asked where Guo Ziyi's agent is now?

"What do you ask Ding Xiang for?" Guo Ziyi was on guard. "She's in Jiangcheng! She still has school work. She can't run around with me before graduation. "

At the moment, Ding Xiang, who is sitting beside Guo Ziyi, straightens up nervously and looks at Guo Ziyi.
