Li Zheng and Shi Yang went out after washing their hands, and then they glanced at each other.

Obviously chatting hotly in the toilet, this time I saw the real person, but I was shy.

It's even more embarrassing than meeting netizens.

Shi Yang's appearance is not far from what Li Zheng imagined.

1.75 meters tall, medium to fat, flat glasses, is really a plus version of learning good shape.

The main enhancement is that his face is bigger, even if he has a straight face, he seems to be smiling, not the kind of smile of a smiling tiger, but the kind of smile that is held back anytime and anywhere.

Especially those eyes, I don't know if they were born or acquired, they are always smiling, slightly demonic.

To sum up, it is shy, wilted, and sullen with aura.

On the other hand, Li Zheng in Shi Yang's eyes was far from what he imagined.

He doesn't wear glasses, but he's handsome, and he's good at chatting......

Shi Yang couldn't help but curse in his heart.

That's not fair!

Your goddamn injustice.

Li Zheng is forced.

Absolutely have a girlfriend.

It's unfair!

The two of them walked all the way back to the street, without speaking.

Along the way, Shi Yang's mind was full of women.

He just wanted to find out if Li Zheng had a girlfriend, what it was like to have a girlfriend, and whether a girl's tongue was cold.

But when they met for the first time, he couldn't ask these shameful questions directly.

Li Zheng's mind was full of explosive, but thinking that Shi Yang was known as the cobalt god after all, the ultimate scholar, and his mind must be full of chemical formulas, it didn't seem good to ask such an unbearable thing when they met for the first time.

Everyone is obviously "all hail" together on the Internet, talking freely in the public toilet.

But without the network cable and partition, the distance is even farther away.

When turning the corner, Li Zheng finally couldn't help it, chose a hypocritical topic, and took the lead in speaking: "This, Brother Shi...... Your problem is so wonderful, so wonderful that I can't even understand it. ”

"Where is it......" Shi Yang scratched his face with a smirk, becoming more and more shy, "I happened to read a paper, some small ideas, didn't I post it in the group, where don't you understand?"

"Mainly...... I'll think about it again......" Li Zheng regretted bringing up this topic.

At this time, Shi Yang was also heartbroken, stared at the ground and asked, "Brother Li, I see your situation...... I guess I have a girlfriend, right?"

"How is it possible?" Li Zheng looked at Shi Yang's resistant look, and his face twitched, "You look down on people, don't you?"

"Ah, no......" Shi Yang looked confused.

"Don't you look down on people?" Li Zheng fell into deep thought, "When I went to take the competition exam, everyone else was like you, and you didn't like to take care of me, didn't you look down on me?"

"Definitely not, brother......" Shi Yang smiled, "It's just that your appearance is too outstanding, I always feel that you are not a person all the way, and it is not easy to face." ”

"Ahh Li Zheng exclaimed, "Is that because I misunderstood everyone?"

"Misunderstanding, misunderstanding. Shi Yang raised his eyebrows and asked, "So you really don't have a girlfriend?"

"That's after college, what do you think?" Li Zheng was a little angry.

"Then I'll rest assured......" Shi Yang became comfortable at this time, and stretched out his right hand with a smile, "People in the same way, people in the same way." ”

Li Zheng also smiled and stretched out his right hand.

But when the two were about to touch.

But they all shrank again, and turned their heads to look around.

This time it's not because of shyness.

It's that I always feel that the other party hasn't washed it.

Li Zheng saw that Cobalt God was quite easy to speak, so he also asked: "Brother Shi, there is something that I have been holding back for a long time, that is... Is that thing true?"

"Hey!" Shi Yang clapped his palms, and suddenly became interested, and his smile became subtle, "You said it earlier, I still think you are a serious person." ”

Li Zheng only urged, "Come on, come on, hurry up, I can't wait." ”

"Hey, that's actually a miscommunication, it's not a residential building. Shi Yang licked his lips, rolled up his sleeves and gestured, "That's my sixth grade......

In Shi Yang's first-hand explanation, Li Zheng finally knew the whole picture of the matter.

It's better than the online version.

In other words, Shi Yang's father, Shi's father, is a middle school chemistry teacher.

When Shi Yang was in elementary school, school was still early, so he would go to his father's school every day after school.

Every now and then, Father Shi would take Shi Yang to the chemistry laboratory, throw Shi Yang some safe chemical toys for him to play with, and then sit next to him to make homework and lesson plans.

Occasionally, when the work was completed ahead of schedule, he would do an experiment with a strong sense of vision for Shi Yang to see.

Shi Yang was fascinated by this, pestering his father every day to do experiments.

On the other hand, he pestered his mother to buy a large amount of experimental equipment and raw materials.

Not only play at school, but also at home, what potassium permanganate + glycerin makes fire out of thin air, what private chlorine gas is not controlled, and the cork bursts and almost poisons and so on.

Every time he broke through a calamity of this level, Father Shi would undoubtedly beat him up and throw away all the chemical stuff.

But every time it was delayed for half a month, Shi's mother would always be unable to bear her son's pleas, and bought him a new set.

After that, the accident was made, the fat was beaten, and the cycle began over and over again.

When a bear kid masters chemistry, it must be a disaster.

Anyway, it's not easy for this family to survive to this day.

By the second half of Shi Yang's sixth grade, the experiment had already been done well, perhaps because he had gone through all kinds of disasters and knew how to avoid danger very well.

Because of this, Shi Yang was given an opportunity.

In the past, he was in the chemistry laboratory with his father, and his father wanted to keep an eye on him, for fear that he would make him bad.

But that day, Father Shi finished his homework in advance, and seeing that Shi Yang was already very skilled, he lay on the table and dozed off for a while.

It was at this moment that Shi Yang stole a fist-sized sodium block and stuffed it into his pocket.

Sodium is a wonderful metal, the chemical properties are very active, and it reacts violently when exposed to water.

Shi Yang, under the supervision of Shi's father, did an experiment of putting a small piece of sodium into phenolphthalein water.

The sodium first floats on the surface of the water and then melts into a shiny ball that swims around and hisses, and the solution turns red with it.

In a nutshell, it is the process by which sodium reacts with water to produce sodium hydroxide and hydrogen gas.

This simple experiment should have stopped there.

But it's to blame his dad for being too talkative.

"During the experiment, you must only use very small sodium, and a larger one will explode. ”

Just this sentence tugged at Shi Yang's heartstrings.

Without relying on any fuel, can metal explode in water?

Shi Yang, who is in the sixth grade, still doesn't believe it.

Finally, on this day, he got such a large piece of sodium and stuffed it into his pocket.

Prepare for a pond or small lake to throw into it when you have the opportunity to see if it will blow up.
