"What does it take to make ice? One big and one small two wooden basins no! A wooden basin, a clay pot, clean water, and most importantly, saltpeter! Lots and lots of saltpeter! ”

Chen Fei danced excitedly, praising his wit.

The action of the child throwing the stone into the water just now reminded Chen Fei of an experiment that his chemistry teacher showed him in high school before: saltpeter to make ice!

Well, don't care how whimsical Chen Fei's head is, from a simple action of throwing stones to saltpeter ice, anyway, he just thought of it, this brain hole is not small.

Saltpeter will absorb a lot of heat when it encounters water, if it is absorbed to a certain extent, the water will freeze because the temperature is too low, this is the simplest ice-making principle, if there is a material, even if it is a hot summer, it can make ice, it can be described as a miracle!

"Ah Fei, are you tired? How do you make ice in summer? Wang Tian stretched out his hand and shook it in front of Chen Fei, trying to wake Chen Fei up.

"Smack!"

Chen Fei grabbed Wang Tian's hand, his eyes flashing with excitement. "I don't have time to explain more, I'll play a trick for you today, you go and help me prepare clay pots and wooden basins, Brother Yin, can you please go back to the Taoist Hall to get some saltpeter?" Of course, the more the merrier. ”

"Saltpeter? What do you want this for? Yin Ping remembered that saltpeter was used by the master for alchemy, looking at Chen Fei's crazy appearance, could it be that he also wanted to refine a pill and taste the feeling of a hundred days of ascension?

"Brother Yin, don't think so much about it first, please go back and get some saltpeter quickly, and I'll show you something fun later."

Yin Ping is not like Chen Fei, there are a lot of nonsense thieves, he is a man of action, and he will ride a horse and leave without saying a word.

Wang Tian quickly prepared something for Chen Fei, a large wooden basin with a small clay pot on it, put clean water into the small clay pot, and the wooden pot was also filled with water.

"Where's the ice? So that you can make ice? Cheng Yanjin looked unconvinced, looked up and down, left and right, and didn't see any clues for a long time, and couldn't help but suspect Chen Fei.

Chen Fei hugged his arms and showed an unfathomable smile on his face: "Uncle Cheng, wait a little longer, and we'll know when Yin Ping comes back." ”

"Fault!" Cheng Yanjin muttered in a low voice, and then said to the little bullies of the Cheng family behind him: "Don't learn from him at this point, you will hang people's appetites at every turn, if you don't want to see what medicine is sold in his gourd, you really want to beat him!" ”

Chen Fei's cheeks twitched: Your whispering is too loud!

didn't let Chen Fei and his party wait long, Yin Ping appeared in everyone's sight on a horse.

"! Brother Yin, this sack behind your back"

"You want saltpeter." Yin Ping rode his horse to the money, threw the sack at Chen Fei's feet, and said coolly with his arms crossed.

"The master is out, so I brought all the saltpeter."

Chen Fei

With such a straight man by his side, Chen Fei didn't know whether to cry for his master or laugh at himself for making a fortune.

"You're welcome, you're welcome" Chen Fei squatted down and opened the sack to take a look, and his eyes were shining with pieces of saltpeter inside, as if he had seen a sack of gold.

"Brother Yin, won't you be hunted down by your master if you do this?"

Speaking of this, Yin Ping rarely showed a trace of embarrassment. "I didn't find any small bags, so I brought them all."

"Yes, this answer is very straight." Chen Fei can't control it so much, since he appeared in front of him, these saltpeters are naturally his, as for the old Taoist priest who found out about the Autumn Queen, what does it matter to him? He didn't steal it, whoever took it will go to whomever he wants.

"Isn't this thing used by Taoist priests for alchemy? You kid can't be trying to do alchemy, right? Cheng Yanjin stretched out his hand and probed Chen Fei's forehead, and said strangely: "It's not hot, why is your brain burned out?" ”

Chen Fei

"Uncle Cheng, you are optimistic, next, it is time to witness the miracle!"

Chen Fei smiled with honey, glanced at everyone like a worldly star, and under the gaze of everyone's wide and curious eyes, he elegantly took out two wooden sticks, set up a piece of saltpeter in the sack, and threw it into the wooden basin water

The saltpeter fell into the water, and the water in the wooden shed suddenly "gurgled" and blistered, and there was a trace of smoke rising from the water.

"Goo!" Wang Tian and the others stared nervously at the water in the wooden basin, looking forward to the magical process of the water turning into ice.

One minute, two minutes, three minutes, five minutes

The nervous group of people around the tub finally felt that something was wrong.

"Ah Fei, what about witnessing miracles? What about the ice making? What about ice? Wang Tian raised up and questioned Chen Fei. The rest of the people also looked at Chen Fei with suspicion.

Chen Fei

"It doesn't make sense! This should be able to make ice! Profound! That's right! I almost forgot! Saltpeter is not enough! ”

Chen Fei's high school chemistry teacher took out a piece of saltpeter and put it in a test tube, and soon made ice. There is only a lot of water in the test tube, which is naturally incomparable to this wooden basin.

So Chen Fei opened the sack and sprinkled saltpeter evenly into the wooden basin.

"Gollum!" A basin of water tumbled violently, and a cold mist rose on the surface of the water, which made everyone feel cool when it floated up, and everyone squinted comfortably.

"Huh! Daddy, look! Cheng Laoliu pointed to the wooden shed and shouted, and everyone looked carefully at the place he pointed to and saw that the water in the wooden basin was actually freezing at a speed visible to the naked eye!

"Oh my God! It's really frozen! What a miracle! Summer freezing, miracles! Hu Di was speechless by the scene in front of him, and in shock, he stretched out his hand to touch the ice, only to feel a piercing coldness pass into his fingers, and he was full of excitement.

"It's real ice!" Hu Di shouted excitedly, and as he spoke, he knocked down a piece of ice and stuffed it into his mouth.

"Smack!" The ice in his hand was slapped off by Chen Fei, and the ice fell to the ground and slid for a long distance.

"You can't eat this ice!"

Chen Fei pointed to the ice in the wooden basin and said, "This ice can't be eaten, only the ice in the clay pot can be eaten!" ”

Everyone put their eyes back on the clay pot, and saw that the water in the clay pot was slowly forming a thin layer of ice, although the speed was very slow, but it was really frozen! Miracles have happened!

Everyone looked at Chen Fei's gaze and suddenly became shocked and worshipped.

Ice! This is something that will only be produced in winter, I didn't expect Chen Fei to be able to make ice in the hot summer, could it be that his hands were ignited by the gods? Is there an immortal law?

"Floating clouds! It's all floating clouds! Don't worship brother, brother is just a legend. The experiment was successful, and was looked at by everyone, and Chen Fei waved his hand modestly.

"The ice in the wooden basin must not be eaten, but it can be kept for subsequent refrigeration! The ice in the clay pot is edible, so what are you waiting for, eat it! ”

Saying that, Chen Fei went to fish for ice first.

Ah! The ice cubes you make yourself are delicious, they are cold and cold, and they are even more delicious if you put a little sugar.

The rest of the people reacted and shouted to grab the ice cubes to eat, especially the most shameless old bastard surnamed Cheng, so he simply picked up the entire clay pot and stuffed the ice cubes into his mouth to eat, while stuffing it, his mouth was still vaguely shouting: "Forehead drops!" It's all forehead drops! ”
