Encounter at the subway station

This statement is a bit strange, and a bit subtle.Li Yeshan was slightly taken aback, and subconsciously looked at Xiao Xingkan, but soon reacted and smiled: "Friends are friends, why do you say preparations?"

"Because we need to ask for consent," Yang Zhao looked up at her with a half-smile, "Although it's good to know each other well, not everyone wants to be disturbed wantonly."

Li Yeshan's smile froze on his face, and he didn't know what to say for a moment.

Xiao Xingkan, who was the only one who could understand the meaning of "preparation" in his mouth, scratched his head and coughed dryly to change the subject: "You and this... are juniors, right? Are you just finishing get out of class?"

Li Yeshan came back to his senses and didn't dare to look at Yang Zhao again. He quickly said, "Ah, he is the president of the student union of the chemistry school. I'm from the student union of our school. I'm here to discuss with him a social activity next week."

Xiao Xingkan said in surprise: "It turned out to be from our college. It seems that I haven't cared about those things for a long time, so I didn't recognize it."

The boy put down his chopsticks, nodded at Xiao Xingkan and smiled slightly: "Senior, my name is Wu Mingqian. I seem to have a little impression of you. I should have seen you during a bed check. You should be Yu Chen's roommate, I don't know if I remember wrong No."

"You know Yu Chen?" Xiao Xingkan asked.

Wu Mingqian nodded: "Have you forgotten, senior Yu Chen was also a member of the student union before, so I was brought up by him."

After the atmosphere calmed down a bit, Li Yeshan also joined their chat. The three of them were all students, and they got together to chat about students' daily affairs. Yang Zhao didn't speak again, and sat down to eat quietly opposite Xiao Xingkan.

They had almost eaten at first, but Xiao Xingkan saw that Yang Zhao didn't speak much and quickly put down his chopsticks. After waiting for Yang Zhao to eat almost, he didn't intend to wait for Li Yeshan and the others. He nodded politely and smiled: "Then we will go first." gone."

"Goodbye senior! Next time we talk—"

"Goodbye, senior."

Yang Zhaoduan passed most of the plates, and Xiao Xingkan asked him in a low voice, "Are you full? If you're not full, we can go to the snack street outside."

Yang Zhao nodded slightly: "Let's go."

After the two came out of the cafeteria, they went to the snack street. At this time, the number of people gradually increased as the end of get out of class was approaching. The two walked side by side in the dim sunlight, keeping a distance that was not too close, but would not be scattered by people. distance.

Xiao Xingkan asked Yang Zhao what he wanted to eat. Yang Zhao looked around and didn't seem to want to eat it very much. He casually pointed to a shop selling Doudou cakes and asked for a meat floss filling, while Xiao Xingkan ordered a yogurt filling.

Yang Zhao originally wanted to pay, but Xiao Xingkan stopped him. Xiao Xingkan said, "If you come to play with me today, let me treat you."

Yang Zhao didn't insist. For things like paying for meals, just make up for it next time.If the division is too clear, there will be no reason to ask someone out next time.

After Xiao Xingkan paid the money and asked Yang Zhao to wait, he turned around and bought some skewers of roasted gluten.

"I don't know if you can eat spicy food, so I didn't let you go." When Xiao Xingkan came back with the bag, Doudou Cake was almost ready.There are seats specially provided for students on the snack street. They found an empty seat and sat down, opened their bags and ate.

They sat on a bench, and Yang Zhao was sitting very close to Xiao Xingkan. The distance seemed to cross the limit a little, but the feeling of sitting next to him and eating together was not too bad. Xiao Xingkan Xingkan didn't hide, but he didn't dare to turn his head to look at Yang Zhao.

"Let me taste yours." Yang Zhao said suddenly.

Xiao Xingkan froze for a moment, turned around and saw him staring at him, and it took him a long time to realize that he was talking about the pie in his hand.

"I bit..."

Before he finished speaking, Yang Zhao lowered his head and bit off the remaining half of the cake in his hand, squinting his eyes and chewing slowly.

The afterglow of the setting sun shining from the top of his head fell on his hair, as if there were golden debris shaking, and the hair became soft. His expression seemed to be enjoying it. If you ignore the aggressiveness in his eyes, he is completely a lazy cat.

Xiao Xingkan stared at Yang Zhao. When Yang Zhao swallowed the food in his mouth, his Adam's apple moved slightly. His face burned instantly, and he quickly turned his head to hide his unease.

"You seem to be blushing." Yang Zhao came over and whispered, "Do you feel this way when I eat?"

Xiao Xingkan held back for a long time, and squeezed out a sentence: "I feel like you are playing a hooligan, but you are not playing a hooligan."

"What you do to your sweetheart can be called hooliganism," Yang Zhao said with a laugh, "this is called honest pursuit."

"You... eat the things I bought and still treat me like this, won't your conscience hurt?" Xiao Xing accused.

"It won't hurt, and there's even a little bit of happiness."

Xiao Xingkan blushed and glared at him, Yang Zhao smiled and handed over the cake in his hand: "I'll eat it for you, don't be angry."

The tone is like coaxing a child.

Xiao Xingkan was so angry that he grabbed the remaining half of the cake in Yang Zhao's hand, and stuffed it into his mouth a few times.

Yang Zhao took over the wrapping paper, grabbed Xiao Xingkan's wrist and got up: "Let's go."

"What's the matter?" Xiao Xingkan stood up and wanted to say that he hadn't finished eating gluten, but was dragged away by Yang Zhao.

Yang Zhao turned his head and whispered in his ear, "Someone is watching us."

While talking, he raised his head and glanced ahead. Xiao Xingkan followed his gaze and found that a few girls who were walking together were pointing at them, with a certain meaning on their faces that he couldn't describe. laugh.

Xiao Xingkan breathed a sigh of relief, not just someone who knew him.

Thinking of this, Yang Zhao didn't explain the relationship between the two thoroughly in the afternoon, which made him a little grateful.

"People who know you?" Yang Zhao asked.

"I don't know," Xiao Xingkan shook his head, "Thank you just now, for not telling us about our relationship."

"It doesn't matter. I'm afraid that if we have anything to do with each other, then there will be no chance."

Having said that, Xiao Xingkan knew that this was Yang Zhao's respect.

"Don't think too much," Yang Zhao held his shoulders and walked towards the subway station, "It's much better to wait for you to introduce me to the people around you than to make a big deal out of it yourself."

"You didn't drive here?"

"Come here by subway, walk along the road you walked again, it seems to have a different feeling."

The two entered the subway station, Yang Zhao was not in a hurry to go through the security check, and looked at Xiao Xingkan with a smile: "Do you want to go home with me?"

"Don't follow!" Xiao Xingkan pushed him, "Don't think about me going back with you."

"Hey," Yang Zhao sighed regretfully, "You've learned to be smart, so it's not easy to lie back home."

Xiao Xingkan pushed him into the security checkpoint.

There is no way to go to the laboratory during the weekend holiday, Xiao Xingkan decided to go again during class next week.

These two days I went to work in a milk tea shop, and Yang Zhao would come to pick him up when he was off work. The two would usually go to the coffee shop next to the subway station to sit for a while, chat for an hour, and then Yang Zhao sent Xiao Xingkan to the subway Stand, and go back to work by yourself.

Yang Zhao said that if you are serious about chasing people, you are very serious. When the two get along with each other, they will be serious and will not exceed the rules. Occasionally, a few indecent words are within Xiao Xingkan's tolerance.

He felt as if he really fell in love with this person, so he became very excited about making a storm bottle.

In the experimental class on Monday, Xiao Xingkan was still doing experiments with Yu Chen. The good thing about doing experiments with Yu Chen was that both of them studied well, and they seldom repeated experiments.

After completing the task given by the teacher, Yu Chen sat and played with his mobile phone while Xiao Xingkan put the tools he brought on the table and began to prepare the solution with a beaker.

"What are you doing?" Yu Chen glanced at him while playing with his phone, and asked.

"I plan to make a storm bottle for a friend."

Xiao Xingkan first mixed concentrated sulfuric acid and concentrated hydrogen | fluoric acid into distilled water to prepare a little glass etching solution, and dipped a small writing brush he brought into the etching solution to write on the bottle.

After carefully writing Yang Zhao's name on it, he put the glass bottle aside and went to find materials for making a storm bottle.

"Making a storm bottle in such hot weather?" Yu Chen expressed doubts.

Xiao Xingkan brought over potassium nitrate, ammonium chloride and absolute ethanol, and took out the natural camphor that he had already bought.He was afraid that the crystals he made would not look good, so he specially bought better natural camphor online.

"It's okay, the laboratory has air conditioning, it should be done."

After the materials were prepared, Xiao Xingkan reckoned how much to increase.Dissolve a certain amount of potassium nitrate and ammonium chloride in distilled water, take out the natural camphor and dissolve it in a certain amount of absolute ethanol, heat the two bottles of reagents in a hot water bath, pour them into glass bottles while they are still hot, and seal them mix.

"Without dyeing?" Yu Chen asked casually.In the past, he also made storm bottles for his friends. Not only did he make one, but he also made colorful ones and put them in a row. The colorful ones are very beautiful.

Xiao Xingkan put the bottle away carefully: "No more, it looks pretty like this."

Now just wait for cooling to crystallize.

He planned to put the bottle here and come back to see it tomorrow, and got up to pack up the used utensils and reagents.

Yu Chen saw two words on the glass bottle from a distance, and squinted his eyes for a while.

Yang... Zhao?

boy, or girl?Gifts for boys need to engrave their names on the bottle?But looking at the name, it doesn't feel like a girl.

Yu Chen didn't take it too seriously, but he left an impression of the name.

The author has something to say: The Beauty of Chemistry - Storm Bottle

The formula on the Internet is 2.5g potassium nitrate, 2.5g ammonium chloride, about 30ml of distilled water, 10g of natural camphor, and about 40ml of absolute ethanol.

I feel that the method is quite simple. I haven't done it yet, and I want to try it someday. Natural camphor is poisonous, so pay attention to safety.I don’t know how effective the glass etching solution is, but these two acids are still a bit dangerous... If you see something wrong, you can tell me, I will change it to orz

Thank you for the nutrient solution of the fish that will definitely pigeon hehe
