Great Tang’s Unparalleled National Teacher

“Squeeze the silk inside first, and then buckle it on the jar. Remember to seal the mouth tightly when you take it out.”

Zhang Feng Thousands of warnings said with a serious face that it can be said that it is the last step and the most important step. As long as the hydrogen is successfully obtained, it means that the experiment has been successful, and it can be promoted on a large scale.

“Yes, Honored Teacher.”

Ma Zhou nodded, he also heard the indisputable tone of Honored Teacher’s tone, and didn’t dare to slack: “Chujun, come and help. “

The two of them squeezed the edge of the silk and started to exert force each other, trying to squeeze the air out of the silk. Of course, they didn’t know what air was, they just kept following the Honored Teacher’s instructions. Commanded to do it.

“It’s okay.”

Zhang Feng saw it almost, waved his hand to stop: “Now you put the silk on the jar.”

The two nodded , Gently unfold the silk and wrap it on the jar.

“Honored Teacher, it’s already set.”

Hao Chujun pulled this corner and said seriously.

“Okay, then you reach in and gently remove the cardboard, and then wait for a cigarette to seal the silk mouth.”

Zhang Feng stared closely While holding the silk, he said with a serious face: “Remember to seal it tightly, preferably with a string.”

The two of them were nodded, continuing their movements, reaching out and slowly removing the cardboard, and obeyed Zhang. Feng ordered that after waiting for almost a cigarette, they slowly removed the silk. At this moment, they speeded up, grabbed the air outlet and tied it tightly with a rope.

“Honored Teacher, it has been completed.”

Ma Zhou handed the silk in his hand to Zhang Feng.

Zhang Feng took it with joy, playing with it in his hand, and rubbing it twice from time to time to feel the softness, but soon the smile on his face disappeared and replaced it with a touch of sadness.

This experiment is finished, and the hydrogen is collected, but how can we know that it must be hydrogen?

Be aware that this thing is a colorless, transparent, odorless, tasteless and insoluble in water gas. In this age without various facilities, there is simply no way to identify it.

However, this thing has another big disadvantage, that is, it has high flammability and is very easy to burn. This is one of the reasons why the use of hydrogen is less.

Combustibility?

Is it possible to try it with fire?

Anyway, there is not a lot of hydrogen in it. It shouldn’t be any danger, and now there is only one way, otherwise there is really no way to tell if it is hydrogen.

Thinking of this, he tilted his head slightly and looked towards Cheng Chumo beside him, revealing a smile.

“Feng’zi, what are you laughing at? is it possible that what bad idea are you making?”

Cheng Chumo embraces his arms, like a grieving woman, for fear Others take advantage of him.

“Go go go, just like you, do you use to protect yourself so tightly? Do not pee and look in the mirror.”

Zhang Feng’s pouting old man Gao, with the same smile on his face: “Now there is a good job. Who of you will do it, there is a reward.”

“What reward?”

There is a reward for three people. It’s the same as vying for fear of falling behind.

“How about one-time ascension benefits?”

Zhang Feng stretched out a finger, slightly smiled.

“Just once.”

Cheng Chumo frowned, twitched his lips: “Forget it, let’s see which one of them will go?”

Obviously, he was a little bit overshadowed by that experiment just now, and now he doesn’t want to go on without good things.

“Dang! .”

Du Gou raised his hand and glanced at the crowd: “Isn’t it just an experiment? What is this?”

He is not worried about any danger in this, anyway, Feng’zi will not harm himself.

“Okay, Dabing is the real man, who is like you guys.”

Zhang Feng stepped forward and patted Du Gou on the shoulder, showing a hint of satisfaction on his face.

“Feng’zi, what exactly do I need to do?”

Du Gou asked curiously.

“Go and light this fire fold, and place it at the silk outlet.”

Zhang Feng showed a meaningful smile, after speaking, he took it out from his waist Handed a fire book to Du Gou.

Du Gou took Huozhezi and was somewhat confused: “Feng’zi, is it possible that you are going to burn this silk?”

“Of course not.”

Zhang Feng laughed, and didn’t explain much: “You can just do what I say.”

Du Gou nodded, he doesn’t understand this, and doesn’t want to control it. It’s best to do it as instructed. , He opened the Huozhe and reached into the silk opening. Zhang Feng opened the opening. At this moment, a ray of fire burst out, and Du Gou quickly threw the Huozhe away and took two steps back.

Seeing this, Zhang Feng quickly tightened the silk hole for fear of revealing a hint of hydrogen, then looked towards Du Gou, and said with concern: “Dabing, how are you?”

What did others say All sacrifices were made for the experiment, so I should be concerned about it.

But this guy seemed to be frightened, and he was a little speechless when he pointed at the silk.

“Feng’zi, this…”

Du Gou pointed to the silk, his face a little ugly.

“It’s okay, don’t panic.”

Zhang Feng comforted him casually, a trace of satisfaction appeared on his face.
