The eldest daughter's voice appeared behind her, Meng Suisui clapped her hands and stood up, saying.

"No, the firewood has been added. Let it burn by itself. Come on, let's go into the house."

Meng Suisui walked in front, and her daughters followed behind her.

After entering the room, Meng Suisui pointed to the head of the kang.

"The fire has been lit, and the kang will be hot in a moment. You all sleep on the kang, and I will get you quilts."

The three younger daughters kicked off their shoes and got on the kang to wait.

The eldest, second and third child helped Meng Suisui get the quilt.

Wrapped in the quilt, I immediately felt much warmer, and my happiness soared.

Lao Wu: "Wow, it's so warm. I'm so happy."

Three minutes later, the six daughters sat neatly on the kang, each of them wrapped in a thick quilt, with only their heads exposed.

My daughter’s eyes are bright and she doesn’t feel sleepy at first sight.

Meng Suisui lit a candle, walked to the kang with the candle, and asked, "Are you sleepy?"

The daughters shook their heads and said, "I'm not sleepy, not at all."

Meng Suisui suggested: "Then let's chat for a while?"

As soon as he said this, he was immediately welcomed by his daughters.

"Okay, I'm just not sleepy."

"It was thundering so loudly outside that I was scared to death. I couldn't sleep at all. It was great to be able to chat."

"That's great, I like listening to my mother talk."

......

I don’t know when they started, but they liked listening to their mother talk very much, and most looked forward to the time when their mother would give them a meeting in the evening.

Mother will always bring them some different thoughts and feelings, and they can also learn a lot.

The boss took the candle and placed it between them.

Meng Suisui wrapped herself in a quilt and sat in a circle with her daughters around the candle.

The third child asked: "Mom, what are we talking about today?"

"Let's talk about the heavy rain today." Meng Suisui wrapped herself in a quilt and said, "I will test you on some common sense about rainy days. The person with the most correct answers will be rewarded."

As soon as they heard there was a reward, the daughters immediately became interested.

The third child eagerly asked: "What reward?"

Meng Suisui said mysteriously: "I won't tell you yet."

She crawled over and took the small notebook she kept next to her pillow every day, and wrote the names of her six daughters in the notebook.

Meng Anyu, Meng Ruoxi, Meng Yourong, Meng Yixi, Meng Shiyuan, Meng Xingchu.

When my mother wrote their names on the paper, their hearts were filled with happiness.

After writing her name, Meng Suisui put down her pen and said, "The rules of the game are that after I tell you the question, you rush to answer it. The first one who answers correctly will write a line under his name. In the end, we will see who has more correct characters."

The daughters nodded to show they understood.

Meng Suisui cleared her throat, raised a finger and said.

"The first question is, can I take shelter under a tree when it rains?"

The children raised their hands to answer the question, and the answers were all unanimous: yes.

Not a single answer was correct, which is somewhat outrageous.

Meng Suisui instantly felt that it was very important to popularize knowledge on what to pay attention to on rainy days.

Lao Liu thought it was certain that she would win the first question, so she raised her hand and said proudly, "Mom, I was the first to answer, can I draw a stroke?"

Meng Suisui held her head against her head and sighed, "You were the first to answer, but you answered wrongly and your answer is invalid."

"What? Doesn't that mean that my sisters and I got the answer wrong?" Lao Liu looked in disbelief and asked again, "Rain can cover the rain, why can't we take shelter under a tree?"

Meng Suisui said seriously.

"Humans are conductors. When the human body comes into contact with a big tree, a strong lightning current flows through the trunk of the tree and generates a high voltage that knocks the person down."

The children didn't understand a bit and asked confusedly.

Lao Wu asked: "Mom, what is a conductor?"

Fortunately, she is good at physics, Meng Suisui replied calmly.

"A conductor is a substance with very small resistivity and is easy to conduct current." To facilitate understanding, she gave an example, "We have iron kitchen knives and aluminum basins at home. Both iron and aluminum are conductors, and most metals are conductors."

Lao Wu asked again, "Is there anything that is not a conductor? If I am not a conductor, can I take shelter under a tree? And I don't have to worry about lightning hitting me?"

That Lao Wu could think of this level at least shows that Lao Wu is a child who is studious, inquisitive and good at thinking.

She had discovered before that Lao Wu had a high IQ and quick reactions, and now her judgment was even more verified.

She always answers questions patiently from children, no matter how trivial they are.

It is precisely because of her that the children are not afraid to ask questions and are happy to communicate with her.

She was very pleased that Lao Wu could ask such a profound question and said.

"There is no house that is completely non-conductive, but some materials have weak conductivity. Substances that are not good at conducting electricity are called insulators. Common insulators include plastic, rubber, glass, and ceramics. The rain boots we usually wear are made of rubber."

She paused and then said, "So we can conclude that if we have to go out on rainy days, for our safety, it is best not to wear metal products and wear rain boots, which can provide insulation."

Lao Wu nodded and said, "So that's it."

At this time, the third child asked again, "Mom, if I don't touch the tree, don't lean on the tree to take shelter from the rain, and just stand under the big tree, will it be okay?"

Meng Suisui shook his head and said, "That's not possible. Although you are not in contact with the big tree, the lightning current flowing through the trunk of the big tree will generate a high voltage, which will flow into the ground and spread around. It will also discharge the human body through the air and cause damage, so even if you don’t hit the tree it’s not safe.”

The children suddenly understood and said fearfully.

"So that's it, then I will never take shelter under a big tree again."

"I went to the mountains to pick mushrooms before and took shelter from the rain under a tree. After hearing what my mother said, I felt that I was really lucky."

"I remember this answer, Mom, what's the next question?"

Meng Suisui raised two fingers and said, "Second question, can I stay by the river when it rains?"

Before he finished speaking, Lao Wu was the first to raise his hand and said, "No."

Meng Suisui's eyes lit up and she asked, "Reason?"

"Is the river a conductor?" Lao Wu asked, "If the river is a conductor, when the river is struck by lightning, people standing by the river may be affected just like people standing under a tree."

Lao Wu is so smart and has a strong ability to draw inferences from one example.

But this issue is more complicated, Meng Suisui pursed her lips and said.

"The conductivity of water is very weak, so pure water is an insulator, but river water and sea water can conduct electricity. The big tree mentioned just now, the wood itself is an insulator, but after the wood is poured with water, it becomes a conductor. The problems involved It's very complicated. If you want to understand it, Mom can buy you some related books and you can study it slowly."

Meng Suisui finished speaking in one breath. She really felt that raising children was not easy, and answering the children's strange questions was even more difficult.

She took a deep breath and said, "Lao Wu answered this question correctly. The answer is not to go near the water, because open areas are very dangerous. Lei will choose the tallest thing in an area to attack. If you stand by the river, it will be easy." There is a risk of lightning strikes or being washed away due to rising water levels.”

Meng Suisui quickly asked the third question.

"Can I run in the rain?"

This time Lao Liu raised his hand first and said, "No."

Meng Suisui looked at her sixth daughter leisurely and asked, "Reason?"

I saw Lao Liu curling his lips and saying pitifully, "The road is slippery. It's easy to fall if you run too fast. I almost fell down just now and scattered the dried meat all over the floor. Although my mother has never complained or scolded me until now, But I feel very sorry that I have done a disservice.”
