In the first one or two decades, although there were controls on nitroglycerin, it was definitely not as strict as it is now. As long as you were willing to spend money, you could get it without any certificates.
Nitroglycerin is diluted to a few tenths of a percent and can be used as medicine to treat heart disease. The higher the purity of the original solution (the yellower the color), the more explosive it is. The engineer used the second-level original solution (the purest first-level solution).
).
If anyone wants to give it a try, just pour a few drops into the palm of your hand, no need to apply it, just slap your hand hard and it will disappear.
This is called collision detonation. There is another way to detonate, which is the trick used by Master Ji. It was also a trick commonly used by people in the industry at that time, called side-drug detonation.
With the headlight shining on him, Master Ji first stuffed the two prepared balloons into the little eyes. This process was very slow and he was careful throughout.
"Okay, give me one of your cannons."
After hearing this, Brother Yu gave him an old-fashioned detonator.
The engineer spotted the location and started cutting the lower part of the detonator with a knife.
"This is a side medicine. It will explode with a small force when it comes into contact with fire. Use this as a primer to detonate nitroglycerin."
As he spoke, he poured out some black powder from the lower half of the detonator, tore open a bag of balloons again, and poured the black powder into the balloon.
With a strong exertion, the balloon was pulled up as far as it would go.
At this time, he took out his lighter and said, "Everyone, get out quickly. It's very dangerous."
"good."
People started to drill out.
"Young man, please stay for a while."
Dou Sprout touched me and said, "Hey, Fengzi, I'm calling you."
"I'm calling you Brother Yu," I looked at Brother Yu.
"It's just you, Xiao Xiang, please stay and help me." Master Ji's voice came from behind.
Dou Sprout and Brother Yu patted me and left.
After just a few minutes, the originally small space felt larger because he and I were the only ones left.
"Master Ji... Master Ji, whatever you ask me to do, I can't do anything."
"Come on, grab me here."
"listen."
Master Ji calmly explained: "The balloon itself is made of rubber and is highly flammable. In addition, there is a layer of oil on the surface. If you press it tightly, I will take some."
"Once it's lit, I'll go out first."
"When I get out, slowly let go of your hand and come out immediately."
"Understood, Xiao Xiang? I've calculated that we have enough time, don't panic."
He called me Xiao Xiangtou, but I was so nervous that I heard him call me Xiaoluotou.
I was so nervous that I swallowed twice and nodded.
"Papa, tapa..."
The lighter may have been dampened. It didn't light up for the first few times, but it took more than ten times to light up.
The flames approached the balloon and slowly ignited.
I pressed against the wall and dared not move. At this time, I could clearly smell the smell of burning rubber.
As soon as the balloon was lit, Master Ji picked up the bag on the ground, turned around and ran out without even looking at me.
"Huh...huh..."
"Calm down, don't panic." I took a deep breath and kept telling myself not to panic.
Ten seconds later, I heard him shout: "Hurry up! Come out!"
I immediately let go, grabbed the small door and crawled out.
"Quick! Quick! Give me your hand!"
After getting through, Master Ji and I ran to the corner, squatted down and held our heads.
moment!
Just hear a bang!
There was a lot of movement and a low sound, as if something was being suppressed and falling apart from the inside.
The smell of sulfur after burning gunpowder made people cough, and a large amount of dust and smoke floated out.
I waved my hands to disperse the smoke, coughed and said, okay, why don’t I go in and take a look.
"No, wait five or six minutes, we'll go in when Ranpaoyan'er comes."
