I make a popular science video and all the emperors learn from it!

After the light curtain explained, the cause and phenomenon of the formation of ghost fire.

The ancients boiled directly!

So that's what happened!

They've been kept in the dark!

"My mother, it turns out that this is the case, I understand it, and you continue to talk about the storyteller. "

"Well, that's how the ghost fire came about. "

"I said that one night, I peed in the old forest, how did the ghost fire follow me, it turned out that it was too light, and it didn't burn when it touched me, it turned out that it was glowing, not burning. "

"Is it phosphorus burning, or is it a descendant who is so powerful that even the ghost fire can figure it out. "

"Understood, understood, the truth is finally revealed. "

"Don't be afraid now, wait until I go up at night to catch two ghost fires and open your eyes!"

“......"

Qin Dynasty.

Ying Zheng glanced at Prime Minister Li Si next to him, "Four, two, seven".

The implication is self-evident.

Learn something!

Look, that's what professionalism is all about!

Later generations have studied the ghost fire clearly, and in the future, when you are in the Qin State, don't pretend to be erudite and knowledgeable.

Li Si noticed His Majesty's gaze examining him, and his face was hot for a moment.

It's a shame.

Not far away, Hu Hai was discussing something with the rest of the princes.

"Gongzi Gao, next time you leave the palace, let's go catch the ghost fire and play together, how about it?"

"This is not good, Hu Hai, the light curtain didn't say that the ghost fire is dangerous, but you can rashly go to the mass grave to catch it... There's always something oozing. "

"What are you afraid of!" Hu Hai patted his chest twice and promised:

"Don't worry, there is this prince to protect you. "

"When the time comes, we will go secretly to make sure that my father does not know about it. "

Hu Hai said excitedly, and his voice was a little louder.

Without noticing, a figure stood behind him.

"Oh, the widow doesn't know what's going on. Ying Zhengpi didn't smile, staring at Hu Hai, "You still want to leave the palace?"

Hu Hai's expression froze instantly.

It's over, and you're going to be grounded again!

Song dynasty.

Zhao Kuangyin patted his head and suddenly realized!

The popular science content of the light curtain still has his cognitive blind spots.

But in any case, the formation and characteristics of the ghost fire are roughly explained.

In this way, there is no need to be afraid of the so-called ghost fire.

It is a great good thing for the country and the people.

Ming dynasty.

Zhu Houzhao is going crazy.

He's worried that he hasn't had much fun lately.

The light curtain is a ghostly fire.

And it seems that this thing is not as evil as it is recorded and heard.

On the contrary, it is very fun.

Zhu Houzhao looked at the dragon's face and yelled at the attendants on the left and right: "I order you, go and get two ghost fires for my fun!"

Ah......h

Left and right attendants, petrified collectively.

There is already a lot of slander in my heart.

Your Majesty, go your own way!

You've always been bold.

We're really scared...

[Continue to popularize science.] 】

[Phosphorus has a wide range of applications and can be used to make matches. 】

[Match is based on the principle of friction heat generation of objects, using the chemical activity of strong oxidants and reducing agents, a kind of fire tool that can be frictionally fired. 】

[The following science popularization of the manufacturing method of matches. 】

[1. The formula of match skin:]

[8 grams of manganese dioxide, 3 grams of red phosphorus, 3 grams of solvent of Fuqiang powder (glue), 5 grams of glue, 3 grams of water. 】

[2. Match formula:]

[8 grams of potassium chlorate, 2.5 grams of manganese dioxide, 2 grams of sulfur, 1 gram of solvent and glue, 0.5 grams of water, and the appropriate amount of pigment is decided. 】

【Production process:】

[1. The production of match skin will be made of various different raw materials. 】

[After being prepared in a certain proportion, sieve 3 times with a 140-180 mesh nylon sieve, the more the better. 】

[(Do not metal, copper sieve) and then mix the prepared solvent in the sieved raw materials, stir into a liquid, brush on the made matchbox with a brush, and dry it. 】

[2. The production of match heads: After preparing various different raw materials in a certain proportion, use a 140-180 mesh nylon sieve to sieve many times. (If it is uneven, it affects the combustion effect)】

[Then mix the sieved raw materials with the ratio of glue and water and mix them into a paste, insert the bought match stalk on the three splints with many small holes, flip and paste the liquid, dry it cool, dry it in the sun, do not put it on the fire to dry, the key attention is that one end of the match stalk should absorb the paraffin. (The oil can be heated and dissolved first, and the end of the stem can be inserted immediately to remove the non-flammable). 】

【......】

Qin Dynasty...

After reading Yingzheng, his head was dizzy.

He had never heard of many of the materials used to make matches.

How did he make it?

But soon, he reacted.

If you can't build it now, it won't have much impact, and it's not too late to build it when you have the strength in the future.

"Come on, write it down quickly, find a replacement, and see if it can be made?" Ying Zheng immediately ordered everyone in the Mo family. (If you read a violent novel, go to Feilu Novel Network!)

Ever since the light curtain appeared.

The status of the Mohists is growing rapidly, and now its influence far exceeds that of Confucianism.

When he turned his head again to look at the light curtain.

I found that I didn't know when it jumped out of a question and answer box!

[Rush to answer the question. 】

[Please answer the following questions correctly within 30 seconds to receive a great reward.] 】

[Is it white phosphorus or red phosphorus used in matches?]

[Option 1: White phosphorus.] 】

[Option 2: Red phosphorus.] 】

[Option 3: Other compounds of phosphorus.] 】

Ying Zheng was stunned for a moment after reading the title, and immediately showed a happy expression.

Red phosphorus, isn't red red?

It's a bonus point!

"Option two!"

[Congratulations on your correct answer.] 】[]

[Congratulations to the following 371 emperors who also answered correctly:]

【......】

[Get Reward: 1,000 boxes of matches.] 】

[Hint: Matchsticks can be lit by rubbing them on both sides of the matchbox.] 】

The next second.

There was a bunch of small paper boxes in front of Ying Zheng.

He casually opened the other boxes and took out a small wooden stick to observe.

Seeing this thing, you need to rub it on fire.

He placed it on the matchbox and slid it lightly.

Thorn~

The flame on the stick is 5.3 stirred.

Ying Zheng was stupid for a while.

Surprised: "This thing is so convenient to ignite!"

After inspecting, he was shocked to find that there were hundreds of matches in one box!

And he's got a thousand boxes!

Song dynasty.

Zhao Kuangyin looked at the match that lit the flame in his hand.

The heart has already turned up stormy waves.

"Matches?"

"It's easier to use than a fire. "

He had seen it among the people.

It was also a small stick.

In fact, it is a strip of fir coated with sulfur.

When starting a fire, you need to use fire or fire knives and flints.

However, compared with matches, the fire inch is a little untabled, and it is obviously easier for matches to ignite the fire, and the flame is stronger.

Even the fire fold looks a little chicken compared to it!.
