When the audience in the front row saw this, they immediately leaned back nervously.
What’s inside this glass box is poisonous gas!
What should we do if these toxic gases leak?
It's not like they were poisoned by poisonous gas!
Seeing everyone's nervousness, Hu Changan also smiled slightly and said: "Everyone, this toxic substance also depends on the concentration."
"In a sealed box, the concentration of toxic substances is relatively high, so mice can be poisoned to death."
"But if it were placed in this entire site, the concentration of this toxic substance would not be enough to cause death."
"Don't worry, I'm standing further ahead than you."
"I will definitely be poisoned to death before you die."
After saying that, Hu Changan also blinked and made a small joke with everyone.
When everyone heard this, they also laughed in a friendly manner.
The atmosphere in the aura suddenly regained its harmony.
Under the attention of everyone, Hu Changan slowly opened the lid of the hand stove.
Among the two hand stoves covered with cotton cloth, one holds charcoal and the other holds briquettes.
At the same time, Hu Changan opened two other hand stoves that were not covered with quilts.
Of these two hand stoves, one is still filled with charcoal and the other is filled with briquettes.
Everyone was slightly surprised when they saw this.
I didn’t expect that what Master Hu said was true!
It turns out that charcoal, like briquettes, will produce toxic gases only when burned under certain circumstances!
This experiment vividly illustrates that briquettes are no more poisonous than charcoal.
Briquettes, like charcoal, are both normal fuels!
Seeing the expressions of sudden realization on the faces of everyone in the audience, Hu Changan also smiled slightly and said: "As the saying goes, seeing it once is better than hearing it a hundred times."
"Today I tell you with facts that briquettes are just an ordinary fuel."
"Although it cannot be said to be 100% non-toxic, it is not much more toxic than charcoal as the rumors say."
"So you can buy briquettes with confidence."
After hearing this, everyone nodded.
Since this is the case, they have nothing to argue with.
However, some people still have doubts: "Master Hu, I wonder what the principle behind this poisoning is?"
"Why is it that just by covering the hand stove with a layer of cotton cloth, the charcoal and briquettes are so toxic?"
When Hu Changan heard this, he also smiled slightly and said: "Everyone, this is because both charcoal and briquettes need enough air when burning."
"When charcoal and briquettes are burned with enough air, they will not produce toxic gases."
"But when charcoal and briquettes are burned without enough air, they release a toxic substance."
"When I cover the hand stove with a layer of cotton cloth, the charcoal and briquettes can only burn when there is insufficient air, which will naturally release toxic gases."
"If this toxic substance is ingested into the human body, it can range from dizziness and dizziness to direct poisoning and death."
"So when burning charcoal and briquettes, you must place the stove in an open space.
"And when you are lighting the stove, you must not close the doors and windows because it is too difficult and cold."
"Even if you just open the door or window a small crack, the toxic gas will flow out a little along the door and window."
"Even if there are some mild symptoms of poisoning by then, there will definitely be no death."
When everyone heard this, they were suddenly enlightened.
It turns out that heating requires so much attention.
They didn't understand before, but now they understand!
In the future, they must place the stove in a ventilated place and never cover it with anything!
When Ah Hua heard this, he suddenly realized.
Last winter, his neighbor walked away from home for no apparent reason.
He didn't understand why at the time, but now, he may understand a little bit.
The neighbor was always thrifty at home and would never open the windows once the stove was lit.
It seems that their deaths are most likely related to this burning furnace.
However, Ah Hua also felt a little curious.
This Young Master Hu seems to know a lot about this kind of thing.
So will he know how to rescue someone if he is poisoned?
With his neighbors’ lessons learned from the past, Ah Hua was inevitably a little flustered.
Facing Hu Chang'an who was standing on the high platform, Ah Hua couldn't help shouting: "Master Hu, I wonder if you know how to rescue someone once he is poisoned?"
When Hu Changan heard this, he also smiled slightly and said: "After being poisoned, you should run to an open place as soon as possible, breathe fresh air, and metabolize the toxic substances in the blood."
"If the degree of poisoning is relatively deep, you may also consider smelling the gas produced when saltpeter is burned."
"When saltpeter is burned, it will release another gas, which can metabolize toxic substances in the blood faster."
When Ah Hua heard this, a big stone fell in his heart.
It’s great. After knowing this knowledge, if you encounter such a situation in the future, you can directly save yourself!
Seeing that everyone had basically no problems, Hu Changan also smiled and said: "Everyone, if you are interested in the future, you can go to Hu's grocery store to buy briquettes."
"Now there is a new batch of good-quality briquettes in Hu's grocery store."
"When the same volume of charcoal and briquettes are burned together, the heat that briquettes can dissipate is definitely higher than that of charcoal."
"Now our Hu's Grocery Store is offering a big discount. You can buy briquettes of the same quality at half the original price."
"After calculation, this briquette is 30% cheaper than charcoal."
After saying that, Hu Changan also left Shi Shiran.
After hearing this, everyone was eager to give it a try.
Since Hu Changan has proven with facts that briquettes are not poisonous, why do they leave out the hotter briquettes and choose slower-heating charcoal?
What's more important is that Hu's Grocery Store is still on sale!
If you buy briquettes now, it’s definitely a good deal!
Having decided, they are going to buy it now!
Thinking like this, everyone couldn't wait to leave Hu's Tea House and prepared to go to Hu's Grocery Store to buy briquettes!
As for the promotion of briquettes like this, Hu Changan also interspersed it in every story.
Thanks to Hu Changan's vigorous publicity, the message that briquettes were toxic was gradually cleared up.
Now everyone in Yingtian City only remembers the experiment they saw in Hu's Tea House.
Almost no one clings to the catchy message any longer.
...
These days, the shopkeeper of Hu's Grocery Store is smiling from ear to ear.
There is no other reason than that the sales volume of briquettes in the store has skyrocketed recently!
