Dad's business kingdom

Chapter 399 Eggs and White Vinegar

At the end of July, Shanghai entered the dog days. Walking on the road was like soaking in a hot spring. Even if you stood still outside, you would sweat all over your body just by standing there. Even dogs would not want to go out in such weather.

Bai Bai just sleeps comfortably under the air conditioner every day. In the evening, he will go to the backyard or walk around the artificial lake with his owner, and eat nutritious food every day. Some people don’t have a dog like this. Comfortable.

The backyard of Yang Guang’s house is relatively comfortable. There is a big tree in the backyard. Under the big tree is a stone table, four stone benches and two reclining chairs. The sun is blocked by the big tree. Lie on the reclining chairs and eat fruits. The season is very comfortable.

After breakfast, Yang Guang took Qiqi and Xixi to the backyard, holding a cup, an egg and a bottle of white vinegar in his hands.

"Papa, what are we going to do?" Qiqi raised her head and asked curiously.

"Let's do a little experiment today!" Yang Guang said with a smile.

"Uncle Yang, what experiment are we doing?" Xixi asked curiously.

"You'll know in a while."

After speaking, Yang Guang put the things in his hands on the stone table.

"Do you know jumping ball?" Yang Guang sat on the stool and turned his head to ask.

"I don't know!" The two shook their heads.

Nowadays, children don't play with these things very much. In the past, many children would play with these things, throwing bouncing balls in their hands and jumping around on the ground.

"Bounce ball is a ball that can jump around on the ground." Yang Guang explained.

"Jumping around?" The two little guys asked in surprise.

"Papa, how high can the jumping ball jump?" Qiqi asked.

"It depends on how hard you use the bouncing ball. The more force you use, the higher the bouncing ball will jump."

"Uncle Yang, where can I buy a jumping ball?" Xixi asked.

"We don't have to buy it, we're going to make a bouncing ball today."

"Okay, okay, let's do it quickly!" Qiqi said excitedly, clapping her little hands.

"Look carefully at what I do, you two will have to do it yourself soon!"

After Yang Guang finished speaking, he put the egg into the cup.

"The first thing we do is put the egg in the glass, and then I'm going to pour the vinegar into the glass."

After speaking, pour the white vinegar into the cup until the white vinegar overflows the eggs and submerges the whole eggs.

"Then, look, is there any small air bubbles in this cup!" Yang Guangping looked at the cup and pointed at the cup at the same time.

The two little ones looked out curiously.

"Really!" The two little guys said in surprise.

"Do you know why?" Yang Guang asked with a mysterious smile.

"Why?" The two little guys looked curious.

"You can think about it!" Yang Guang said with a smile.

Adults should take children to do some small experiments before they are seven years old, so that they will be interested in science.

"Because eggs spit bubbles," Kiki said.

"It's very close, but it's still wrong!" Yang Guang smiled and shook his head.

"Because the egg is exhaling." Xixi said.

"Still not right, but close."

The two little guys frowned and thought in distress.

After a while, Xixi said shamelessly: "Uncle Yang, we don't know, just tell us!"

"Okay, I'll tell you." Yang Guang smiled helplessly.

He didn't expect them to really give the correct answer, he was just cultivating their ability to think.

After Yang Guang finished speaking, he took the cup into his hand and held it in front of them.

"There is a chemical reaction between eggs and vinegar."

"Papa, what is a chemical reaction?"

"The chemical reaction is like, um..." Yang Guang thought for a while and said: "Let's take eggs as an example. You can't eat rabbit meat when eating eggs, because it can easily cause stomach pains, which means that many things are put in the mouth. Together, there will be some bad or good phenomena."

"Dad usually cooks, and by adding salt, oil and chicken essence to the dishes, he can make delicious food. This is also a chemical reaction."

"Oh!" The two little guys nodded.

"Look, eggs and vinegar will produce a chemical reaction. This is because the main component of egg shells is calcium carbonate, and the main components of vinegar are acetic acid and acetic acid. They are both types of acids. Acetic acid and calcium carbonate produce chemical reactions. reaction, there will be carbon dioxide, and carbon dioxide is these bubbles."

The two little guys looked at Yang Guang in confusion, not knowing what he was talking about.

Seeing the confused expressions of the two little guys, Yang Guang smiled and said, "Okay, you don't need to know everything, that is to say, putting eggs and vinegar together will produce carbon dioxide."

"Carbon dioxide is the breath that is usually exhaled, that is carbon dioxide."

"Uncle Yang, is this carbon dioxide?"

After Xixi finished speaking, he let out a breath from his mouth.

"Yes, that's it." Yang Guang said with a smile.

"Papa, when will the jumping ball be made?"

"It will be done soon."

After talking about the aura in Yang Guang's hand, the bubbles in the cup were born quickly, and the cup was like a feast, and the cup was completely submerged by the bubbles.

In just a snap of the fingers, all the air bubbles are gone.

"Okay, let's get the eggs out now."

After speaking, he took the egg out of the cup, and then peeled the egg, only to see that the egg white turned into a crystal clear light yellow.

Yang Guang put the egg about [-] centimeters above the table. As soon as he loosened his hand, the egg fell out of his hand and jumped up and down on the table.

"This is the jumping ball!" Yang Guang said with a smile.

"I want to play!" Kiki said.

"I want to play too!" Xixi said.

"Okay, don't grab it. No one can play with this bouncing ball. You can make the bouncing ball and play with it yourself. Now I'll go and get two eggs."

After speaking, Yang Guang took away the eggs on the table, went to the living room and threw them into the trash can, then he went to the refrigerator and took two eggs to the backyard.

After putting it on the table, he said: "Okay, Qiqi, you do it first, Xixi, take a look, if Qiqi fails to do it, you will do it."

"En!" The two little guys nodded firmly.

After finishing speaking, Kiki picked up the egg and put it in the cup, and then poured the vinegar into the cup.

"Pour some more." Yang Guang said.

Kiki poured some white vinegar into the cup again.

"Okay, that's enough."

Qiqi stopped pouring white vinegar when she heard it.

"Come on, let's let him play."

After Yang Guang finished speaking, he put his palm on the cup, and countless bubbles were born in an instant.

Just in the blink of an eye, all the bubbles disappeared.

"Now we'll take it out."

After Yang Guang finished speaking, he took out the egg and put it in front of Qiqi.

"Qiqi, you peeled off the eggshell."

"Okay, Papa!"

After speaking, Qiqi peeled off the shell of the egg, and saw a crystal clear light yellow egg inside.

"Now you can play it as a bouncing ball!" Yang Guang said with a smile.

"Papa, won't it break?" Kiki asked nervously.

"Father's previous eggs were not broken, and this one will not be broken either."

A bouncing ball made of ordinary eggs is easy to break, but this egg was conceived by Yang Guang with spiritual energy, so it won't break easily.

"Look, Dad is here to show you." Seeing that Qiqi dared not throw the egg out, Yang Guang took the egg from Qiqi's hand, raised it to a high place and threw it down. The egg jumped back and forth on the table .

"Really!" Qiqi said in surprise.

After speaking, he took the egg in his hand and played with it by himself.

"Okay, now it's Xixi's turn." Yang Guang said with a smile.

"Yeah!" Xixi nodded firmly.

After speaking, she also put the eggs into the cup, and then poured white vinegar.

"Pour some more!"

Xixi poured some more white vinegar.

"Come on, let's play it off."

Countless bubbles were born again.

"Okay, peel off the shell of the egg and you can play it as a bouncing ball." Yang Guang took the egg out of the cup and handed it to Xixi.

Xixi peeled off the egg shell, held it in her hand and threw it out, jumping up and down on the ground.

Two little guys are chasing a jumping egg in the backyard.
