Episode 244: [Saltpeter Ice Making]

Shuai Guo has not come to Li Chengqian again since he was beaten by Li Chengqian.

But today Shuai Guo is happy to come!

Li Chengqian, Little Tiger, Zhengtai, and the child sitting on the table are eating happily around a pot of things!

"Why are you here?" Li Chengqian raised his head, glanced at Shuai Guo, and asked.

Shuai Guo opened his mouth to speak, but heard the little tiger say to Li Chengqian: "The third brother has no share, he can't give him my share, mine is only so much!" ”

Zhengtai also made a statement: "Mine can't be divided!" ”

Shuai Guo didn't know what they were sharing, so he saw that the milky white mucus on the corner of his mouth stretched out two cute little hands, covered the basin, and said, "Mine, mine!" ”

"Say what?" The handsome pot finally interjected before Li Chengqian could speak!

"Divide the ice cream." Li Chengqian said, "If you want to eat, wait for tomorrow." ”

"Ice cream?" Shuai Guo was stunned, "What did you invent in the East Palace?" ”

He stretched out his head to look, and saw a copper basin with a layer of white solid things, smelling a sweet fragrance, a bit like milk, and I don't know what it was, but it was smoking!

"This is ice cream?" Shuai Guo asked puzzled.

"Yes." Li Chengqian said.

The child said happily, "It's delicious!" ”

Shuai Guo was not interested in this thing, shook his head and said, "Big brother, I came to you to show you this." ”

As he spoke, he took out an account book from his arms and handed it to Li Chengqian to read.

Li Chengqian took it and took a look, the handwriting inside was beautiful, it was a woman's handwriting, he turned a few pages, all numbers and couldn't understand it. "What is this?"

"This is the income of the wheelchair shop and tea house we cooperate, and today is the day of dividends, big brother, take a look." Shuai Guo said.

Li Chengqian looked at the account book: "Dividends?" Oh, that's fast, a month has passed. ”

He returned the ledger and said, "I don't understand, just do as much as you say!" ”

Shuai Guo took it and said, "Take out the big account and divide it, and keep the small account in the store for use, and we will divide it into fifty yuan this month." ”

Fifty runs! Li Chengqian did the math and said that the money that Little Tiger and Zhengtai lost this month was all out of his pocket, and there were more than ten yuan. That's not much!

But it looks like it's a long stream, and it's not bad.

Li Chengqian said: "Do what you want." ”

"Okay, I'll ask the housekeeper to deliver the money tomorrow." The handsome pot responded.

Li Chengqian turned around and saw that the three little guys were eating with relish, and the whole person was about to throw himself into the basin. Li Chengqian shouted: "Be careful! ”

The little tiger shoved the ice cream into his mouth with a spoon and replied, "Got it! ”

Shuai Guo tilted his head and asked, "Big brother, what are they eating?" ”

"Ice cream, I mix it together with goat's milk and sugar, and then ice it into ice cream like this!"

A few days ago, Li Chengqian was bored, so he thought of ice cream, a summer thing, so he tried to make it. The Tang Dynasty wanted to find a cow to milk is not easy to find, I heard that cattle are all laborers in the field, the Tang Dynasty is based on agriculture, the status of cattle is very high, who will raise cows to milk it, so Li Chengqian had to use goat's milk.

"Ice in the cellar can freeze milk out like this?" Shuai Guo asked again.

"I can't." Li Chengqian shook his head.

Relying on ice cubes to freeze a pot of goat's milk into ice, this situation or if conditions permit, but on this hot day, as soon as the ice comes out of the cellar, it will continue to dissolve into water dripping, and it is naturally impossible to freeze goat's milk.

"How is that done?" Shuai Guo is really curious now!

"Hee-hee......" Yu'er laughed over there, "Third brother, I'll play a trick on you!" ”

"What trick?"

Er'er took a bowl, then filled a bowl of water in the wooden barrel next to it, put it on the table, pretended to be an adult, and said to the handsome pot: "This is a bowl of water, right?" ”

Shuai Guo rolled his eyes, this is taking him as an idiot, asking such a question.

He nodded, "Yes." ”

"Don't take your eyes off, look at it!" As she spoke, she put her two little hands on the bowl. But her hands were too small to cover the whole bowl, so she sprinkled some white powder into the water, which was also seen by the handsome pot.

Although Shuai Guo saw it, he didn't expose it. Such a cute sister, he still watched her pretend to be very patient.

But then he couldn't hold his mind, because he saw that the water in the bowl was actually smoking, and then it froze!

His eyes widened, and he stretched out his hand to pull away from Er'er's little hand, so that he could see it more clearly, but when he reached aside, he stopped, afraid that the magic power would be in Er'er's hand, so he didn't dare to interrupt Er'er.

After a long while, half of the bowl of water was frozen, and the child proudly took his hand away and boasted, "Look, I turned the water into ice!" ”

Shuai Guo opened his mouth wide, picked up the bowl, looked up and down, and it was really frozen!

He looked up at Li Chengqian, Li Chengqian's face was settled, and then at Little Tiger and Zhengtai, they also looked normal, he couldn't help but ask: "How is this done, does it have magical powers?" ”

"Hey...... hey," the child smirked.

Zhengtai smiled: "Third brother, I'll also perform this magic trick for you!" ”

"Magic?"

"This word was said by the eldest brother!" Zhengtai took a bowl, went to get a bowl of water, and then put his hand on the top of the bowl on the table, just like a child just now.

Shuai Guo reached out and held the hand that came from behind one of Zhengtai's hands, then opened it, took the white powder in his hand, and said, "I know, I'll try it!" ”

The little tiger rolled her eyes, she didn't expect to be recognized by the handsome pot so quickly, she still wanted to perform, it seems that there is no chance!

Shuai Guo put the white powder into the water in the bowl, and then without covering the bowl with his hands, he stared straight at the water inside and slowly froze.

"This ...... What are these powders? Shuai Guo asked in shock.

"Saltpeter." Li Chengqian said.

Shuai Guo pointed to the powder left on his hand and said, "Is this what makes the water freeze?" ”

"Yes. This thing freezes the water, it absorbs heat when it encounters water, it sucks the water into ice, and then you want to know why, I can't explain it. "This question Su Mi asked, Xiao Chen asked, Little Tiger asked, Li Chengqian only knew that saltpeter absorbs heat, let him explain how it can absorb heat, that is the ability of the physics teacher!

Shuai Guo didn't break the casserole and asked in the end, picked up a bowl of ice and looked at it seriously, then looked at the ice cream in the copper basin, and asked, "Can this saltpeter be made into ice cream and eaten together?" ”

The little tiger laughed and said, "Of course, you can't add saltpeter to the ice cream and eat it, but you can put the saltpeter in the water of the wooden basin, and put the ice cream in the copper basin, and you can freeze the ice cream and not eat saltpeter diarrhea!" ”
