"Do you want to use the gunpowder in the fireworks to trick the wall?" I frowned and asked, impossible, if the gunpowder in the fireworks is so powerful, it will definitely restrict sales, in fact, anyone can buy fireworks.

Everyone can buy it, which means that the gunpowder inside is mediocre, and I believe that in order to ensure a public security environment, even kitchen knives must be registered in real names, there will be no such low-level control loopholes.

The cousin obviously knew this, she looked at the fireworks, then at the map, and suddenly took the pencil from her ear and poked it on the map: "There is a way!" ”

“…… What's the solution? I asked.

"Hee-hee, I'll surprise you tomorrow, I'm sure I'll get the horse back!" My cousin sold a pass, smiled, and turned back to her room.

I looked at the map, and the location she had just poked with a pencil was a factory.

"Shanghai fertilizer factory?" I can't figure it out, what are you doing with chemical fertilizer, I just finished studying the recipe, is this going to farm again? I really don't understand her.

The night breeze is slightly cool, the air is refreshing, there are snacks left over from their previous meals on the balcony, I poured a glass of red wine despite the injury on my arm, and enjoyed a good time for a while, and when I returned to the private room after drinking, Anlan had turned off the lights and slept, this private room was smaller, and the two sofa chairs were spliced head-to-head into a bed, Anlan took up a small half, leaving me the other half.

I lay down next to An Lan in my clothes, the wine was quite strong, and coupled with the body fragrance on An Lan's body, I was dazed and soon fell asleep.

Who dreams first, wakes up a pillar of incense, looks at the time, it is already more than seven o'clock in the morning, the door of the private room is open, there is talk and laughter outside, the warbler sings and dances, it is very lively.

I got up, moved my muscles, and came to the outside room, thinking that I was engaged in entertainment activities, but I didn't expect them to get together to make dumplings!

"It's not the New Year, why are you making dumplings?" I asked, puzzled, what an idleness.

"Today's 'ambush', eat dumplings!" Xiaoxiao said with a smile.

Lying in the groove, ambush, means that the short spring and summer seasons of the fairy tale city are coming to an end, and it is about to enter the "hot summer" season, as we all know, the fairy tale city has five seasons.

I looked up and saw that it was okay, the lights were still on, and the air conditioner could be used, if the power supply disappeared, I really don't know how to spend this "hot summer"!

Qian Dazhuang is also there, and he is working hard with a pot of beef and onion filling, no need to ask, it must be steak, Aozhou steak stuffed dumplings, it's really luxurious!

"Where's my sister?" I asked, Anlan was not there.

"She's gone out to investigate," Lianye said, "and said she'll be back soon." ”

I drank a glass of boiled water, climbed to the top floor, habitually patrolled around, although it was only more than seven o'clock in the morning, but today's sun father-in-law worked very hard, shining and hot, forcing the zombies who had been active all night to shrink to the shade early, and the ground was quiet.

I looked at the factory area in the distance, and soon found that my cousin was flying there at a low altitude, I didn't know what I was looking for, and after flying for a while, she landed, walked into a blue-roofed workshop, and when she came out again, she was holding a large plastic bag in her arms.

Two minutes later, my cousin flew back to the top of the tower.

"What is this?" I asked, inside the plastic bag was a white crystalline powder.

"Fertilizer."

I remembered, the Shanghai fertilizer factory.

My cousin opened the plastic bag, and an indescribable smell rushed out of the bag, but it was not very pungent, I smelled it!

I grew up in the city and didn't have the opportunity to come into contact with the substance of "chemical fertilizer", but when I returned to my hometown in the countryside of Northeast China with Dongdong during the Chinese New Year last year, she had chemical fertilizer at home, which was reserved for spring ploughing. It feels a lot like coarse salt.

Dongdong's father removed the tarpaulin on the fertilizer, two of the bags were written in blue Songti - urea, and on the other bag, three words were written - ammonium nitrate.

The taste of the latter is the smell of fertilizer in my cousin's bag!

"Ammonium nitrate!" I blurted out.

"Huh? Can you smell this? My cousin was surprised.

"I've seen it at Dongdong's house, why are you doing this?" I was puzzled and asked, "Isn't ammonium nitrate or urea both agricultural fertilizers?" ”

"The ammonium nitrate content in chemical fertilizer is relatively low, and this is the raw material I found from the fertilizer factory to make chemical fertilizer, high-purity ammonium nitrate, 99.5%."

"That's high-purity fertilizer!" I laughed.

"Oh, you're still a top student, and you've learned chemistry in vain? Pure ammonium nitrate will be violent at a high temperature of more than 400 degrees, and the power is much stronger than fireworks! ”

I was indeed a top student back then, but the fertilizer ...... Can this thing be deceitful?

Still a little unconvinced, I used a pencil to write out the chemical equation in the blank space of the map: NH4NO3.

"Completely decomposed?" I asked my cousin.

"Yes, complete decomposition."

Complete decomposition refers to the complete decomposition under conventional conditions, if according to the molecular composition of ammonium nitrate, complete decomposition into various basic elements, it is impossible to do, unless, the condition for a chemical reaction to occur is: nuclear bombardment.

Completely decomposed, there would be no oxygen, and I quickly deduced the chemical reaction equation.

4NH4NO3→3N2+2NO2+8H2O。

Under the condition of 400 degrees of high temperature, water is also gaseous, which shows that ammonium nitrate will be completely converted from solid state to gas under high temperature conditions of 400 degrees, and the volume of ammonium nitrate will expand by about 1700 times under the conditions of horizontal atmospheric pressure and room temperature, and because the gas has no expansion coefficient, under high temperature conditions, the expansion multiple will be far more than 1700 times, and the volume of this substance will be drastically changed, which will be accompanied by a huge energy release, which is chemically called: tyranny!

"It's really going to be treacherous...... How powerful? I looked up and asked my cousin.

"I don't know, try it."

I found a large flower, 24 rings, disassembled one of the canisters, there was a lead underneath, the lead was connected to the gunpowder, and on top of the gunpowder was a fireworks bomb containing metal powder and other substances (responsible for the shape, color, etc. of the fireworks), my cousin poured the ammonium nitrate from the top into the fireworks canister, poured it a little in, poked it with a baseball bat, and then poured it down, and stacked it layer after layer.

"Be careful, don't blow it up before it ignites." I reminded.

"No, don't worry."

Soon, about three-quarters of the ammonium nitrate was filled into the tube, and with the remaining quarter, I stuffed a can of Coke into it, just the right amount of weight.

After the ammonium nitrate egg was manufactured, my cousin carefully held it (it could not be put on its side, it might be ignited by the tail flame of the aircraft), flew to a car in the corner of the playground, knelt on the ground, stuffed the canister into a certain part of the bottom of the car and got stuck, and after lighting the fuse, she was afraid that it would be too late to take off, so she turned around and ran, and ran to the back of another car 30 meters away in one breath and hid.

The lead was very long, I connected it in series with four cylinders, I kept looking at it with a telescope, the fuse burned for almost half a minute, and the little flame went into the cylinder, and after another second, boom!

Lie down in a big groove! The car was actually deceived into flying more than a meter high before falling heavily, and the cousin who was hiding behind the car 30 meters away was not spared, and was thrown out by the shock wave and fell into the mud.

"It's okay!" I shouted loudly, and my cousin lay on the ground, slowing down for a few seconds before getting up, she shook the dust off her head, looked back at the mushroom cloud created by the fraud, grinned at me, and gave me a thumbs up! Awesome!
