In fact, the principle of popcorn is very simple, that is, in the process of heating, the temperature in the pot continues to rise, and the pressure of the gas in the pot also increases, when the temperature rises to a certain degree, the rice grains will gradually become soft, and most of the water in the rice grains will become water vapor.

Due to the high temperature, the pressure of water vapor is very large, so that the rice grains that have become soft expand, but at this time, the pressure inside and outside the rice grains is balanced, so the rice grains will not burst in the pot, when the pressure in the pot rises to 4 to 5 atmospheres, suddenly open the lid of the popping pot, the gas in the pot expands rapidly, and the pressure decreases quickly, making the pressure difference between the inside and outside of the rice grains larger, and the high-pressure water vapor in the rice grains also expands sharply, and the rice grains burst instantaneously, that is, popcorn, these are all when I was in junior high school, the physics teacher told me, at that time, I felt that I admired a person so much, it turned out that I couldn't magic, and I was very sad for a while。

Soon it was Wang He's turn and me, the old man took the corn in Wang He's hand, put it in an iron pot, covered it, put it on the stove to burn, shook the bellows, "huh, hush", the fiery red stove was red, the children's cheerful smiling faces, and the children stared at the stove with wide eyes.

After about a quarter of an hour, I heard the old man say, "Attention, the cannon is blowing." "The children were scrambling to dodge, and I covered my ears with my hands. I only heard a "bang", which exploded the children's joyful mood, and after a burst of smoke, the old man opened the lid of the pot, and the snow-white popcorn came out of the pot, grinning one by one, and slid into the bag.

At this time, the friends in the village hula gathered around, untied the bag, and the popcorn was slightly yellow. Like a daisy in late autumn, he put it in front of his eyes, grabbed a handful and chewed it in his mouth, and the incomparably sweet fragrance went straight to the bottom of his heart. I often eat a handful, and I want to eat a handful, and a full furnace can destroy the light for a while, and the luxurious happiness is still faintly wrapped around the tip of the tongue and wrapped in the heart after a long time.

In my previous life, I just finished every time. A group of us kids went to grab the popcorn scattered on the ground, and it was so much fun that I forgot the taste of jì for so long. I only remember the excited expressions of a group of children covering their ears, and the old man would clean up the remaining "fish that slipped through the net" in the pot, put them in a small bowl, and give them to the naughty children. They ate with snow-white popcorn crumbs stuck to their mouths.

I watched Wang He fill the dustpan with popcorn. Hurriedly picked one up and stuffed it into his mouth, Wang He hurriedly instructed me: "Slow down, be careful to burn your tongue, there are many more here." I looked at Wang He's serious expression, and suddenly felt that this sentence was extremely familiar, it was all my mother who told me before, and after so many years, I still haven't changed it. This is a problem with impatience.

I still remember when I was young in my previous life, my family used bud rice to pop popcorn every time. Once I saw someone else's child, took the rice to burst, a loud noise, came out of the pure white pop, I was very envious, but my mother didn't give me rice, I felt too wasteful, so I stole some out, I remember that time was the most fragrant one, now you can buy all kinds of popcorn, but the best taste is still that time.

Later, there was a cylindrical and yellow popcorn made of corn, crispy and delicious, and the children in the village and I sometimes played with it, blowing on the round holes, and amusing each other, that we are not called popcorn, it is called konoha, my mother will take a small half bag of sorghum rice every time, and then harvest half a bag of konobo, in fact, the best noodle is still made of saccharin, half a bag of sorghum rice with two bags of saccharin, it is particularly delicious.

Later, everyone said that saccharin is a chemical, and eating too much is not good for the body, but at that time, the white sugar was too expensive, or saccharin was affordable, and saccharin was still very sweet.

Kangle fruit is very long to get out, my mother will put them on the kang head, so that in the cold winter, directly lying on the kang to eat, and there is no need to worry about it will resurge, I basically go to school, take a long one, and the two people at the same table one and a half, from the morning to the end of school, but also special hunger.

At that time, although there was no money in the family, no one was inferior to this little money in the general family, and basically met the wishes of children, in fact, parents also liked to eat, after all, sorghum rice was generally left in the family, and a few seeds were planted in the yard, and there was no need to wait, and a lot of sorghum rice would be produced.

I miss those days very much now, but I think it's interesting, because I'm now re-experiencing, living with great nostalgia before, this should also be the greatest happiness, and I can re-experience the happy days before, I thought about it for a while, and suddenly felt something, as if I had figured it out, and put the steaming popcorn in my hand into Wang He's mouth.

I laughed while grabbing a handful from the dustpan, putting it in my mouth and continuing to eat, "Brother Wang He, it's still hot popcorn, it's delicious, it's so fragrant" Wang He ate the popcorn I just put in his mouth, and felt that it was really sweet, no wonder the big girl likes to eat hot food, it is indeed a little more delicious.

Wang He looked at me running in front of him, the eldest girl seemed to be a little happier than usual today, how to say it, it was the kind of thing that seemed to have nothing on her mind, happy like a child, Wang He thought about it, and felt that it didn't seem to be particularly right, so he didn't continue to think about it, but seeing the eldest girl so happy, his mood was also very good.

I don't know what Wang He thinks, I just feel in a good mood, I ate the popcorn in the dustpan, and when I saw that Wang He's mouth was gone, I fed him, I ate happily, and I was very happy, Wang He held the popcorn in the half-dustpan, walked behind me, and felt very happy.

When we went back, my mother had already come back, and I came back very early today, it seems that my mother is also very blessed, Grandma Zhang saw us coming back, and hurriedly greeted us, "I still thought, you should come back at this time, we are all ready to have dinner, why have you been in line for so long" Grandma Zhang asked while pouring out the popcorn in the dustpan.

"It's already very early for us to come back, and there's still a long queue behind us," I said to Grandma Zhang, and Grandma Zhang suddenly remembered after listening to it, "Look at me, I'm old, I forgot, this year is still popcorn, it's the first time I've come, no wonder there are so many people, the children should be in a hurry, okay, wash your hands, get ready to eat, popcorn will be eaten tomorrow" After Grandma Zhang finished speaking, Wang He and I looked at each other and smiled.

We are on the way, we have eaten almost, and the people in front of us have also divided some, for us children, one to eat, has basically eaten almost, the people in the village know, everyone is not bad for these bites, so generally the first explosion is good, will be given to a few acquaintances of the children to taste fresh.
