Chemistry lab class.

Lao Li Dong walked around and took a look, and the students were concentrating on experiments. The atmosphere is good or bad. Yixue: They are all in the back position. At this time, Lao Li walked to the front, Chen Xi was called away by a girl to help, Shu Yan They did their own business and didn't care about her, she was doing the drainage method to collect oxygen, the three gas collection cylinders were full of oxygen, she first did the experiment of charcoal burning in oxygen, and after doing it, she also asked Shu Yan and Lu Yuan, she felt that she could do the same without Chen Xi, and then did the experiment of wire burning in oxygen, Shu Yan looked at her and always felt that something was wrong, but she couldn't remember it for a while, she put the wire into the bottle, the experimental reaction was very violent, she was still appreciating it with satisfaction, suddenly"Bang!" and "pop!", and in the blink of an eye, the three bottles in front of her were tragic, the bottom of the bottle used to make the wire burning exploded, only half of it stood on the table, and the other two were bounced to the ground and shattered. Shu Yan saw the bottom of the bottle burst, and finally remembered it. Everyone looked at her in unison, Yixue was stunned, and then Lao Li came down, "Yin Yixue, what do you want to do, do you want to blow up the laboratory!"

Yixue lowered her head and whispered, "Absolutely don't dare, this time it's a mistake, a mistake." ”

"Hey, forget it, fortunately, the alcohol lamp didn't break. ”

Yixue smiled when she heard him say this, "yes, yes." ”

Lao Li glared at her, "After school today, you come to clean the laboratory." After Lao Li finished speaking, he walked away, saving himself from being angry.

Yixue suddenly cried with a sad face.

Lu Yuan said with a beating: "Okay, but you should be prepared for the next bomb and blow up the school." ”

Shiya pushed him away, "Lao Li is still fine, he only cleaned it once." ”

"He's really worried about me, he doesn't worry about what if I accidentally blow up the lab?"

Lu Yuan came up again, "Have backbone! I support you." ”

Shiya scolded him, "You go to die, blow you up!" It didn't take long for the class to end, and everyone went back. Sitting in his seat, Lord Chenxi began to interrogate, "Have you not read a book?"

"Looked. ”

"Then why did the bottle explode. ”

"I don't know, it's going to blow up if it's done well. ”

Chenxi narrowed his eyes and looked at her, "Are you sure you saw it?"

"Well, I didn't look at it. ”

"Did you know that it's dangerous for you to do experiments without reading books? What if you hurt yourself? ”

"You're here. This sentence made Chen Xi speechless, and his heart was sweet.
