Leilei's little head thought for a while, picked up the little spoon he had when he was eating and pressed it on the pencil head. The plasticine on the other end did not disappoint him and jumped up.

"Leilee is so great!" The little aunt praised him first.

Leilei smiled shyly and looked back at his second uncle: Am I great?

Meng Chenyi gently touched his nephew's head: "Well. Leilei wants to try the frog again?"

Leilei looked at the paper frog that he couldn't press no matter how hard he was, with a sad face.

Meng Chenjun suddenly turned his head and said secretly to his nephew's little ear: "Leilee, I'll teach you a way not to press with your hands, you can blow with your mouth."

Blowing his little mouth? Leilei looked at the fourth uncle half-believingly. Meng Chenjun pulled him to the paper frog: "Come on, blow it."

"Second Brother, what are you asking him to do?" Meng Chencheng frowned, only knowing that his naughty Fourth Brother must be troubled again.

"Anyway, you can't press it. What's the matter if you blow it? Is it, Leilei?"

It seemed reasonable for the fourth uncle to say this. Leilei's little head thought about it again, and his little mouth blew behind the paper frog. He exhale, and the little frog really flew up in one breath.

Grandpa Meng laughed.

Seeing the frog that he could not pressed flies up, Leilei happily ran after the frog that was flying away, picked up the paper frog and then blew it with his small mouth.

"Depending on the good things you did, what bad ideas you came up with." Meng Chenxi couldn't help but scold Xiao Si, who was thinking, "What did you turn it into when the two brothers taught you a good leverage class."

Meng Chenjun wiped his nose and said unconvincedly: "My second brother didn't say to me. If I teach Leilei like this, it's easier for Leilei to make the frog fly."

The two college brothers smiled mysteriously all the time.

While the college students at home were teaching the children just now, Ning Yunxi hurried to the balcony to wash the diapers her son used to dry at night. Sometimes she looked back at the situation in the living room. She felt relieved when she heard the laughter in the living room.

I never thought that my son was chasing the paper frog that was blown away and chasing him to the balcony.

"Leilei?" Ning Yunxi looked down at his son's little figure.

Leilei lay on the ground and blew the paper frog with his little mouth.

Ning Yunxi was stunned: "Who taught you?"

"It's the fourth brother!" The little girl Meng Chencheng ran over to complain.

This little girl at home is smart and slick, and neither of the college students can say anything.

After pulling up his son who was lying on the ground, Ning Yunxi thought about it and had to do it himself. When she walked to the living room, she first asked Xiao Si: "What principle did you use in this method? Come, I have been in junior high school and have studied physics, which can explain the truth."

Xiao Si didn't expect to be tortured by his teacher at home. When he asked, he was stunned: "I don't know."

"You don't know how you can teach him to do this?"

"Sister-in-law. I only know that I was playing like this when I was a kid."

"Don't you know you never thought about going over and knowing why?"

After being criticized by Teacher Ning incisively, Xiao Si thought it made sense and turned around to ask the second brother, the second brother of the academic master at Xiang’s family: “Second brother, why?”

"This is the conversion of wind energy into kinetic energy. Like the plane we are on, we can fly in the sky, and there is this principle inside." Meng Chenyi gave a lecture to his younger brother.

There is actually so much knowledge in it. Grandpa Meng and Grandma Meng were curious and exchanged glances with each other: It is different to have a teacher at home. Children can learn knowledge while playing.

Ning Yunxi began to transform his son's paper frog, and folded it on the frog's tail and legs. He grabbed his son's little hands and slowly taught him where to press, how to press and how to let go.
