After a wave of business, the boss returned to the popcorn, preparing to "pop" it again.

Ye Shengge's eyes lit up, and he was finally able to fully see the entire working process of this old-fashioned popcorn machine.

Li You and the other onlookers were also very interested.

I saw the boss adding some corn kernels and sugar into the tank, and then closed the lid.

Then burn the fire in the stove more vigorously, then put the tank on the stove and start to rotate the tank by hand.

"Just keep heating it like this, and then you can pop the corn kernels into popcorn. It's quite amazing when you think about it." Ye Shengge said.

Li You smiled and said: "This is based on the principle of pressure difference..."

During the continuous heating process, the temperature inside the tank continues to rise, and the pressure of the gas inside the tank will also continue to increase.

At the same time, when the temperature rises to a certain level, the corn kernels will gradually soften. Most of the water in the corn kernels will turn into water vapor.

Water vapor will cause the softened corn kernels to begin to expand.

However, because the pressure inside and outside the rice grains is balanced at this time, the corn kernels will only expand and will not explode.

When the pressure in the tank rises to four or five atmospheres, the cover of the tank is suddenly opened. The gas in the tank will expand rapidly when it comes into contact with the atmosphere, causing the pressure to decrease sharply.

As a result, the pressure inside and outside the corn kernels loses balance. This will cause the high-pressure water vapor in the corn kernels to expand rapidly, causing an explosion in an instant, and the corn kernels will explode.

Then it became popcorn.

Li You briefly explained the principle.

After hearing this, Ye Shengge suddenly realized that this was what happened.

Several people around also heard it, and everyone looked at Li You. They were probably thinking, this young man knows a lot.

Keep watching.

After a few minutes, the boss took the tank away from the stove. This meant that the pressure in the tank was enough and it was ready to "explode".

Everyone was in high spirits, and this was undoubtedly the moment that everyone was looking forward to the most.

The same goes for Li You and Ye Shengge.

Some people covered their ears with their hands. It can be said that they are afraid of the explosion but also like to watch it.

Some people also took out their mobile phones and started recording.

Ye Shengge also took out his mobile phone and started recording.

The boss used a large linen bag to cover the mouth of the tank, and then used a shovel to forcefully pry the opening and closing device of the machine cover.

There was a "bang" sound as promised, and the smell of popcorn spread.

Everyone is very happy.

Ye Shengge was also very happy and said excitedly in Li You's ear: "It's quite interesting. I'm so lucky today!"

Li You nodded, "It's really not easy to come across this kind of old-fashioned popcorn machine now."

The boss once again packed the popcorn into bags. At this time, many people came to buy it.

Ye Shengge also bought a bag each of popcorn popcorn and rice popcorn.

"Let's go." Ye Shengge said.

Li You nodded.

The two of them continued walking forward.

Ye Shengge opened both bags and motioned to Li You to get some popcorn.

Li You took a little of both kinds of rice krispies and ate them while walking.

The taste is still good. Whether it is popcorn or rice popcorn, the taste is still in my memory.

At the same time, Li You also felt that popcorn was more delicious at this time.

Ye Shengge was also eating, and said while eating: "It's very delicious. Rice Krispies are also delicious, and they feel even better than popcorn. Nowadays, there are basically only cornflakes in movie theaters, not rice popcorn. Including other things.

In some places, you can often see popcorn for sale, but rarely, or even almost no popcorn. I don’t know why?”

Li You said: "Maybe it's because the current popcorn machines can basically only process corn and cannot process other grains including rice."

"Is that so?" Ye Shengge said, "The old-fashioned popcorn machine is more comfortable. Although the operation is a little more troublesome, all kinds of grains can be processed."

Li You said: "However, it is best to eat less popcorn produced by old-fashioned popcorn machines, because the lead content may exceed the standard."

"The lead content exceeds the standard? Is it true, boss?" Ye Shengge was very surprised.

Li You nodded, "It's indeed true."

Then he explained the reasons why the lead content may exceed the standard.

Ye Shengge said slowly: "I didn't expect it to be like this. But it shouldn't matter if you eat a little occasionally, right?"

Li You smiled and said: "It doesn't matter. Otherwise, I wouldn't have let you buy it just now."

"That's fine." Ye Shengge was very happy and continued to eat the popcorn in his hand without any psychological burden.

Li You smiled and continued eating.

Both of them were eating until they slowly finished both bags of popcorn.

It's already 10 o'clock in the morning, and it's almost time to go back.

"Let's go back." Li You said.

"Okay."

The two people walked out of the market and came to where Li You parked his motorcycle.

I got on my motorcycle and went back to the hotel.

……

Rongcheng.

Taxi driver Zhu Xing is taking a passenger to his destination.

While driving, Zhu Xing was voice chatting with several colleagues in a peer group.

Many times, taxi drivers will chat while driving.

As we chatted, we came to the topic of lunch.

"I went to the Lotus Restaurant to eat Mapo Tofu again at noon today. I feel like missing it after two days."

Lotus Hotel is exactly the one Zhu Xing mentioned before, a restaurant where Mapo Tofu is very delicious.

It's delicious and the price is affordable. Not only Zhu Xing likes to eat there, but many of his colleagues also like to eat there.

"Okay, I'll go there to eat Mapo Tofu too. It just so happens that my current list is to go there."

"The Lotus Hotel is just an ordinary restaurant. Other dishes in the restaurant are neither good nor bad, but Mapo Tofu is the only dish that, for some reason, tastes so good that people never get tired of eating it."

"In Chengdu, the only places where Mapo Tofu tastes better than the Lotus Hotel are the five-star hotels. Even the four-star hotels probably can't."

"I had a customer say last time that the Mapo Tofu in Jiahe Hotel is not as delicious as the Mapo Tofu in Lotus Hotel. Jiahe Hotel is a four-star hotel, and its reputation is still good in Chengdu."

"Look. Even four-star hotels are not good. Not to mention that all four-star hotels are not good, but there will definitely be some that are not good."

"..."

Zhu Xing listened to various discussions among his colleagues. If he had been there before yesterday, he would have also talked about how delicious the Mapo Tofu at Lotus Restaurant was.

But now, he said: "The Mapo Tofu at Lotus Hotel is good. However, the Mapo Tofu I ate at a place yesterday was far more delicious than the Mapo Tofu at Lotus Hotel. Both of them

It’s not on the same level at all.”

These words quickly aroused the interest of colleagues.

"Haha! Have you discovered something new? Lao Zhu, please tell me where it is?"

"It tastes too much? Is it true? How delicious does it have to be to say it tastes too much?"

"It can't be those five-star hotels, right? No matter how delicious the food in those five-star hotels is, it means nothing to us."

"..."

Colleagues responded positively. Zhu Xing was very satisfied and said: "Don't worry, it's not a five-star hotel, it's just an ordinary restaurant with a relatively large area. It's true that it's too delicious. It's just a place.

It’s a bit far, more than 200 kilometers.”

"More than 200 kilometers?"

My colleagues were also speechless. It’s more than 200 kilometers away! No matter how delicious it is, there’s no way they would eat it!

Zhu Xing added: "Of course it's unrealistic to eat every day, but I think it's okay to eat once every ten days and a half."

"It's not worth going once every ten days and a half a month. It's too far, no matter how delicious the food is, it's not worth it."

"If it's just better than the Mapo Tofu at Lotus Hotel, it's certainly not worth it. However, it's far more delicious. Let's put it this way, the Mapo Tofu there is the most delicious Mapo Tofu in the world. Don't

Even the Mapo Tofu of the Lotus Hotel cannot compare to the Mapo Tofu of the Jincheng Hotel."

As soon as this was said, colleagues all thought it was too exaggerated.
