Yuchi Xunyu stood outside the door, "Uncle Wuyang, do you know how to control ghosts?"

Jia Ping's head was full of black lines.

The rebellious boy Yang Yuan hesitated for a moment, then said, "Is that porcelain bottle a treasure?"

However, Chen Xiang said firmly: "Someone dares to assert that there must be a world in that porcelain vase."

This imagination is very grand, yes, the writing has a future.

"Hey……"

Li Yuanying just recovered now. He tidied his hair at the sideburns, and said lightly: "There is righteousness in my heart, so there is no need to be afraid of ghosts and gods."

This cargo ratio seems to be quite talented.

Jia Pingan waved, "Who will try?"

Everyone looked at each other, and finally the rebellious boy Yang Yuan walked in.

"Is there a formula?" He felt that such a treasure as the Royal Envoy must have a secret.

"Yes." Jia Pingan asked him to pour in the alcohol and shake it, and then poured out the alcohol.

Huo Zhezi lit up, Yang Yuan looked at him, "What's the secret?"

"Call me Dad."

Yang Yuan hesitated, "Father."

A group of clubs actually regarded scientific phenomena as a matter of gods and ghosts. Jia Pingan felt that they should be taught a lesson.

puff!

The porcelain bottle sprayed out blue fire, and then there was a whistling sound, like ghosts crying and wolves howling.

Yang Yuan's hands were shaking.

"Don't shake."

The second student stepped forward and still said, "Dad."

All 17 people tried it once, and then you looked at me and I looked at you, and they were a little excited.

"Cough cough!"

Jia Ping'an felt that it was time to reveal the secret to this group of sticks.

"It's alcohol."

Jia Pingan pointed to the small jar, "What is alcohol? You don't understand what I said. To put it simply, the wine you drink is purified to get rid of impurities...the alcohol content is higher."

Yuchi Xunyu asked: "Maybe drink?"

You mallet!

Jia Pingan casually threw the brush over.

"Be serious!"

Yuchi Xunyu smiled dryly, "I'll get some good food later, the only thing missing is good wine."

Everyone nodded.

It really is a bunch of weirdos.

Jia Pingan continued: "Why is there a blue fire and howls? Because alcohol is easy to volatilize, come and ask, the wine is not warmed in winter but the smell of alcohol is very weak?"

The crowd nodded.

"If you put the wine in a porcelain bottle..."

Yuchi Xunyu hurriedly said: "It smells very good if you put it in warm water in winter."

Jia Pingan glanced at him, "This is the characteristic of alcohol, it is volatile. If you heat it up, it will evaporate from the wine..."

He picked up the porcelain bottle, "Put the alcohol into the porcelain bottle, shake it a few times, let the wine finely cover the inside of the porcelain bottle, and then pour out the excess alcohol. At this moment, the alcohol in it starts to evaporate, but everyone, the mouth of this porcelain bottle is not big. So the volatilized alcohol accumulates in the porcelain bottle, mixes with the air, and ignites the fire at this moment..."

Everyone was stunned, Li Yuanying was the first to react, "What is air?"

Jia Pingan was speechless, "Air is the air that exists in the void around us. You keep breathing, you inhale the air, and what you exhale is exhaust gas."

Yu Chi Xunyu said: "But why does the exhaust gas exhaled by a certain woman smell bad, while the exhaust gas exhaled by a beauty is like orchids and musk deer?"

You are a bitch!

Jia Pingan couldn't bear it anymore, picked up the thin stick next to him and went up to beat him.

"Don't you know the etiquette of silence when you speak?"

Yuchi Xunyu was beaten with his head in his arms, but he didn't dare to fight back.

This is the power of this experiment.

Jia Pingan came back panting, and continued: "There is no scent like orchid or musk. They are all human, and the smell they exhale is similar. If they are exposed to cold, the exhaust gas they exhale is still smelly. Both men and women are the same."

He went on to say: "You can do an experiment when you get home, get a charcoal basin to burn firewood, and then cover the charcoal basin with a lid, remember, the lid is tight..."

"The fire will go out."

Yang Yuan seemed to have worked at home, and Jia Ping'an was very pleased with this, "Yes, you can find out why it goes out later?"

Everyone shook their heads, and Jia Pingan said: "This is because the combustion of firewood needs the assistance of air. When the lid is closed and the air is isolated, the firewood will naturally go out. Alcohol is volatile and mixed with air, which is explosive. The gas, but there was an opening, and someone lit it with a fire, and the mixed air inside exploded, if the opening was sealed, it would explode, but there was an opening, and the deflagration gas rushed out..."

Everyone only felt that they had seen a new world.

"Is this new learning?"

This is amazing, isn't it?

Even Li Yuanying was thinking.

"But why do ghosts and wolves howl?" Yang Yuan was puzzled by this.

"Simple." Jia Pingan said: "You can go and have a look at the flute, why can it make a sound? It's all because there are holes, and people blow..."

Jia Pingan looked at everyone, wanting to see who had a higher IQ.

"Sir!" Yang Yuan suddenly became excited, "Blowing air is like deflagration. The smaller the hole, the sharper the sound... A certain person used to make a flute at home, and a certain person tried it..."
