Mother Niu had a sad expression.

Because their family is about to give birth to a daughter who has gone from the city to the countryside to farm.

What a tragic thing it would be, it would be a tragedy for the whole family.

......

"We don't have to worry, there are 8 handsome guys and beauties who will be selected to appear on the stage......"

Soon, 8 handsome guys and beauties took the stage and formed three groups.

"Don't worry if you don't get selected, we have a second experiment in a while, and many people have a chance!"

The grouping is complete and the experiment begins.

"Use what you have learned to determine the acids and bases as quickly as possible, pick them out, and put them on both sides......

"There is a reward for answering correctly!"

"What reward?" Niu Mimi was the first to be selected and became more courageous. She smiled and looked at Lu Shuiyue with a look of adoration and asked.

"When Pink Romance comes out, I'll mail you 5 boxes, what do you think?"

"It's a great gift. Xiao Yahong smiled and said, "A professor who is very important to our teacher Xiao Lu once asked Teacher Xiao Lu to give him a strawberry, but she only sent two catties to others, that is, two boxes, this time the winner's prize is 5 boxes, that is the most generous time for Teacher Xiao Lu!"

Xiao Yahong's words caused a burst of laughter from everyone present.

"Vinegar is acidic, baking soda is alkali and you can smell it easily......" said a little boy who stood up very bravely.

"Xiao Yahong brought a solution to the brave man who stood up first, and let him smell it well!"

Xiao Yahong took a solution and gave it to the boy.

"Warrior, are you sure you want to hear it?" Xiao Yahong confirmed.

"I'm sure I want to hear it!" the little boy hesitated, but finally nodded bravely.

"You're so brave!"

The little boy put the solution Xiao Yahong brought over to his nose and sniffed it.

A strong, pungent smell rushed to his nose and hit the door of his head.

The little boy's face showed a painful expression that he was about to die.

The audience laughed, and so did the boys and girls on stage.

"Are you sure it's acid?, look at your expression like poison!" Lu Shuiyue asked with a smile.

"I'm sure it's sour!" the little boy nodded vigorously, "but I'm not sure what kind of acid it is?"

"You don't need to determine what kind of acid it is, as long as you can determine the acid and base, you can ......"

The experiment continues.

The show is ongoing.

The heat of the scene was completely mobilized by Lu Shuiyue.

The rhythm of the entire stage is also under Lu Shuiyue's control.

The show moves forward in a tense and pleasant process, with clear priorities and rhythmic ups and downs.

The directors and planners on the periphery are also integrated into the program in the process unconsciously.

"Wouldn't it be better if this show was broadcast live?" the director suddenly came back to his senses and found that he was actually attracted by the content of the show.

He looked at the time, and it turned out to be a little embarrassed, and before he knew it, his attention was completely focused on the show, and it had been 15 minutes.

How long has he been filming this show, and he has never been attracted by the content of the show.

Not only was I not attracted before, but every time I filmed, it was an ordeal, and it tasted like the torment of chewing wax.

Lu Shuiyue, this little girl is so terrible, he can grasp the rhythm of a show so well.

Today's "We Love Science" and the previous "We Love Science" are completely two programs, and Lu Shuiyue alone has completely subverted and sublimated this program.

As a director, he really admires Lu Shuiyue's ability.

Meng Feifei may think that Lu Shuiyue is a genius host, but at this time, the director thinks that Lu Shuiyue is a genius director, if she directs a movie or TV series, it must be a very exciting TV series or movie.

There are also planners who have the same feelings as the director.

The show was planned by him, and he invested his own efforts in every show and every link.

But every time it came out, the results disappointed him.

Each previous episode of the show seemed to be pieced together one by one.

It's like a mirror that's broken and snaps it all together, but the crack is clearly in front of you.

But this time is completely different, Lu Shuiyue perfectly connected and integrated the show, just like a brand new mirror that has just left the factory, there are no cracks, it is a whole.

He was thinking that if Lu Shuiyue planned a show by himself, it might be more exciting than the show he planned, I don't know how many times.

......

"Now it seems that Group 2 has won the final victory!" Lu Shuiyue announced the result.

"Teacher Xiao Lu, I don't think it's right, their No. 5 test bottle didn't detect whether it was acidic or alkaline!"

"yes, when the marble was put in the vial 5, there was no reaction!"

Players from the other two teams questioned it.

"So how can this problem be solved?"

"What else can be said about it but acidic and alkaline!"

"Maybe it's a neutral ......"

"Then let's check if it's a neutral solution!"

"This time we use a killer feature, that is, the btb indicator, can anyone tell me what kind of state the acidic, neutral, and alkaline solutions present in the BTB environment?"

Of the 9 boys and girls on the stage, none of them knew what state he would be in.

Lu Shuiyue did not say the answer directly, but turned her gaze to the small audience in the audience.

"Let's see if there's still a chance, whoever has the ability to say what state they are presenting can come on stage and operate this experiment himself!"

This is a difficult question, and many of the small audience in the audience don't know about it.

However, there were still two young audience members who pondered for a moment and raised their hands bravely.

"Okay, you two are the warriors of the challenge...... A handsome little boy, and a beautiful little girl, you come up together......"

Neutral, alkaline, and acidic properties are green, blue, and yellow in the BTb indicator environment, respectively.

......

Meng Feifei glanced at the time of the show, which had been going on for nearly 50 minutes.

Now, an experiment has not been completed, 50 minutes have passed, what about the second experiment?

If the second experiment is carried out, it will most likely take more than two hours, and there is no way to do it even if it is a post-editing exercise.

If the recording of the show is stopped now, then it will be particularly abrupt and hasty, and the perfect state of the show has not been presented, she looked at the director and Mi Yue who were standing on the periphery a little hesitantly.

"Director, Fei Fei seems to mean that time has gone out!"

"Is the time already overdue, how can it be so fast!"
