Hu Changan looked at the people sitting in the audience, cleared his throat and said: "Everyone, I believe you have all heard the rumors that briquettes are poisonous."
"I came here just to take this opportunity to clarify the rumors about briquettes."
"I admit that briquettes may indeed release toxic substances when burned."
"But when charcoal is burned, it also releases toxic substances."
"Under normal circumstances, the amounts of these toxic substances are very slight and will not cause human poisoning."
"Only in extreme cases, the concentration of these toxic substances will increase to a height that ordinary people cannot bear, causing people to coma or die."
"Theoretically, whenever fuel is used, there is a possibility of poisoning."
"But people don't necessarily need to use fuel in winter, right? What's more, under normal circumstances, the probability of people being poisoned is really very small."
"My briquettes are just an ordinary fuel, just like charcoal."
"My briquettes are not poisonous!"
Everyone was a little confused when they heard this.
None of us are educated people, nor do we know any scientific knowledge.
They half understood what Hu Changan said.
Why does Mr. Hu say that the briquettes are poisonous at one moment and not poisonous at the next?
Is not this contradictory?
Can this briquette be used or not?
Looking at the confused faces of everyone, Hu Changan also smiled slightly and said: "As the saying goes, seeing it once is better than hearing it a hundred times."
"Next, let me demonstrate it to you."
With that said, Hu Changan ordered his servants to bring up four large glass boxes.
In each large glass box, there are three mice.
At present, no one has bred white mice yet, so Hu Changan can only use local materials and order people to capture twelve mice directly.
These rats were all fat and strong, and they seemed to have stolen many villagers' food reserves.
In each glass box, there is a hand stove.
Two of the hand stoves had no cover, while the other two were covered with a heavy cotton cloth.
After lifting four large glass boxes, Hu's servants lifted a long table onto the high platform.
The servants carefully lifted all four glass boxes onto the long table.
This is also to make it easier for people sitting in the back row to see the experimental results clearly.
While the servants were setting the table, Hu Changan also smiled slightly and said to everyone in the audience: "Everyone, I'm going to do an experiment for you today."
"As you can see, there are three mice in each glass box."
"This mouse is our experimental subject."
"These glass boxes are airtight, and the air inside cannot circulate to the outside."
"In other words, as long as the mouse in the glass box is still alive, it means that the air in the glass box is not poisonous."
"If the mouse in the glass box dies, it means the air in the glass box is poisonous."
"There is charcoal or briquettes in every hand stove."
"Two of the hand stoves are filled with charcoal, while the other two are filled with briquettes."
"The hand stove is not covered with cotton cloth, which represents normal use."
"A hand stove covered with cotton cloth represents abnormal use."
"Today I will use facts to prove that my briquettes are as poisonous as charcoal!"
Now, everyone finally understood.
It turns out that Mr. Hu wants to use mice to simulate the human living environment and prove that his briquettes are as non-toxic as charcoal.
When everyone saw this, they were all a little curious.
This is the first time they have seen someone use mice to simulate the human living environment.
This is also the first time they have seen someone use this method to prove themselves.
They are all looking forward to the final experimental results.
Seeing that everyone's interest was piqued, Hu Changan also smiled slightly and said: "It will take some time for the results of this experiment to come out."
"By the time this book is finished, the result will be known."
"Next, I won't disturb everyone's enjoyment of listening to books."
"Now I would like to ask Mr. Bai to explain to you the 23rd chapter of Dream of Red Mansions, The West Chamber's wonderful lyrics and the dramatic language, The Peony Pavilion's beautiful songs are heartwarming!"
With that said, Hu Changan made an invitation gesture towards Mr. Bai, indicating that Mr. Bai could start storytelling.
Mr. Bai also bowed his hand and took over the conversation.
And everyone's attention was gradually attracted by Mr. Bai's storytelling again.
Everyone was gradually immersed in the world of Dream of Red Mansions.
Just when everyone was listening intoxicated, someone in the audience suddenly couldn't help shouting: "Look, everyone, the mouse in the glass box on the left seems to be dead!"
This person was sitting relatively close to the high platform, so naturally he could see more clearly.
Just when he was about to lower his head and take a sip of tea, he suddenly noticed that the mouse in the glass box was lying on its back and motionless!
Now everyone's attention was focused on the glass box.
I saw that in the glass box on the left, the three mice were indeed motionless and could no longer die.
The hand stove in this glass box is covered with cotton cloth!
Looking at another glass box covered with cotton cloth on the hand stove, the mouse inside is also lying limply at the bottom of the box. It looks like there is more air coming out and less air entering.
However, in the other two glass boxes that were not covered with cotton cloth on the hand stoves, the mice inside were lively and energetic.
When everyone saw this, they were all stunned.
They all knew that the two glass boxes covered with cotton cloth simulated fuel usage under very normal scenarios.
After all, when using a hand stove, no one would cover it with a layer of cotton cloth when they are full.
Is what Mr. Hu said true?
Can fuel become toxic only when burned under certain circumstances?
At this time, Mr. Bai also stopped at the right time and set aside time for everyone to look at the glass box.
Seeing that everyone had finished watching, Mr. Bai cleared his throat and continued to talk about Dream of Red Mansions.
Soon, the rest of the Dream of Red Mansions was finished.
It was at this time that Hu Changan climbed onto the high platform.
At this time, the mice inside the two hand stoves covered with cotton cloth were already dead.
But in the other two hand stoves that were not covered with cotton cloth, the mice inside were still alive and kicking.
Seeing this, Hu Changan also cleared his throat and said with satisfaction: "Everyone, it seems that the results of our experiment have come out."
"As I expected, fuel will only release toxic gases when burned under certain conditions."
"But as long as the fuel is burned under normal conditions, no toxic gases will be released at all."
As he spoke, Hu Changan slowly opened the two glass boxes containing the dead mice.
