Seeing this, the audience in the front row immediately leaned back nervously.

This glass box contains poisonous gases!

What if these toxic gases leak out?

They don't look like they're poisoned by poisonous gases!

Seeing everyone's nervous looks, Hu Changan also smiled slightly, and said, "Everyone, this toxic substance also depends on the concentration. ”

"In a closed box, the concentration of toxic substances is relatively large, so rats can be poisoned."

"But if you put it in the whole site, the concentration of this toxic substance is not enough to kill people."

"Don't worry, I'm even higher up than you."

"I'll be poisoned before you die."

Saying that, Hu Changan also blinked his eyes and made a joke with everyone.

When everyone heard this, they also laughed friendly.

The atmosphere on the aura suddenly regained harmony.

Under the attention of everyone, Hu Changan slowly lifted the lid of the hand stove.

In two hand stoves covered with cotton cloth, one is placed with charcoal, and the other is placed with honeycomb coal.

At the same time, Hu Changan opened two other hand stoves that were not covered with quilts.

Of the two hand stoves, one is filled with charcoal and the other is filled with honeycomb coal.

Seeing this, everyone was also slightly taken aback.

I didn't expect what Young Master Hu said to be true!

It turns out that charcoal, like honeycomb coal, only produces toxic gases when burned under certain circumstances!

This experiment vividly illustrates that honeycomb coal is not more toxic than charcoal.

Honeycomb coal, like charcoal, is a normal fuel!

Looking at the suddenly realized expressions of everyone in the audience, Hu Changan also smiled slightly and said: "As the saying goes, it's better to see than to hear." ”

"Today, I will tell you with facts that honeycomb coal is just an ordinary fuel."

"Although it can't be said to be 100% non-toxic, it's not much more toxic than charcoal, as rumors say."

"So you can buy honeycomb coal with confidence."

When everyone heard this, they also nodded.

Since this is the case, they have nothing to argue about.

However, some people still have doubts: "Young Master Hu, I don't know what the principle of this poisoning is?" ”

"Why is it that just a layer of cotton cloth is put on the hand stove, and this charcoal and honeycomb coal are so toxic?"

When Hu Changan heard this, he also smiled slightly: "Everyone, this is because charcoal and honeycomb coal need enough air when burning. ”

"Charcoal and honeycomb coal do not produce toxic gases when burned with enough air."

"But when charcoal and honeycomb coal are burned in a lack of air, they release a toxic substance."

"When I put a cotton cloth on the stove, the charcoal and honeycomb coal can only be burned when there is not enough air, so that toxic gases are naturally released."

"If this toxic substance is ingested into the human body, it can be dizzy and dizzy, or directly poisoned, and it will kill you."

"So when you burn charcoal and honeycomb coal, you must put the hand 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 too cold."

"Even if you just open a small crack in the door or window, the toxic gas will flow out a little bit down the door and window."

"Even if there are some mild symptoms of poisoning, there will definitely be no death."

When everyone heard this, they also suddenly realized.

It turns out that this heating has to be so exquisite.

They didn't understand before, but now they do!

In the future, they must honestly put the hand stove in a ventilated place, and never cover it with anything!

When Ah Hua heard this, he also suddenly realized.

His neighbor walked around his house for some reason last winter.

At the time, he didn't understand why, but now, he may have understood a little.

The neighbor had always been frugal in his house, and once the stove was lit, he would never open the windows.

It seems that nine times out of ten, their deaths are related to this burning furnace.

However, Ah Hua also had some curiosity in his heart.

This Young Master Hu seems to know a lot about this kind of thing.

So will he know how to rescue him if he is poisoned?

With the lessons of his neighbors in front of him, Ah Hua was inevitably a little flustered.

Facing Hu Changan, who was standing on the high platform, Ah Hua couldn't help but say loudly: "Young Master Hu, I don't know if you know how to rescue you once you are poisoned?" ”

When Hu Changan heard this, he also smiled slightly, and said: "After poisoning, you should run to an open place as soon as possible, breathe fresh air, and metabolize the toxic substances in the blood." ”

"If the poisoning is deep, you can also consider smelling the gases produced when saltpeter burns."

"When saltpeter is burned, it releases another gas that can metabolize toxic substances in the blood faster."

When Ah Hua heard this, a big stone in his heart also fell.

It's good that after knowing this knowledge, if you encounter this situation in the future, you can directly save yourself!

Seeing that everyone basically had 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 honeycomb coal." ”

"Now there is a new batch of honeycomb coal in good condition in Hu's grocery store."

"The same volume of charcoal and honeycomb coal are burned together, and the heat emitted by honeycomb coal is definitely higher than that of charcoal."

"Now our Hu grocery store is making a big deal, and we can buy the same quality honeycomb coal at half the original price."

"After conversion, this honeycomb coal is 30% cheaper than charcoal."

After speaking, Hu Changan also left the scene with Shi Shiran.

Hearing this, everyone was also eager to try.

Since Hu Changan has proved that honeycomb coal is not poisonous, why do they use hotter honeycomb coal instead of hot and slow charcoal?

What's more, Hu's grocery store is still on sale!

If you buy honeycomb coal now, it is definitely cost-effective!

It's decided, they're going to buy it now!

Thinking like this, everyone couldn't wait to leave the Hu Teahouse, ready to go to the Hu Grocery Store to buy honeycomb coal!

And like this honeycomb coal promotion, Hu Changan also interspersed him in every storytelling.

Under Hu Changan's vigorous publicity, the message that honeycomb coal is toxic has gradually been washed away.

Now everyone in Yingtian City only remembers the experiment they saw in the Hu Teahouse.

Almost no one is holding on to the message of chasing the wind and shadows.

......

These days, the shopkeeper of Hu's grocery store is simply smiling from ear to ear.

There is no other reason, just because the sales volume of honeycomb coal in the store has skyrocketed recently!
