The Goddess Shines on America

One second to remember 【】, to provide you with wonderful novel reading.

The best place to experiment with explosives is not in the room, not to mention that Alice has already rented an area separately. Far from the depths of the plain more than 800 meters away from the inter-county expressway and 320 meters away from the institute in a straight line, the pastures here have been cleared. Considering the actual situation, Alice certainly does more than just pour the concrete floor, as long as you make room.

"You have seen it too. This is our main target at the moment. Sandbags, marble, concrete bricks, and many other materials, but I think you definitely want to see its power in the dirt clearing the most right now?"

Mai Mi had always responded with suspicion, and Gein Alice seemed to deal with the situation too simply. Explosives in the form of transparent crystals are really unheard of. According to the attitude of the developers, this is still a great thing, it seems to be more powerful than RDX.

Of course, Wu Mi has been studying at West Point for two years, and there is also a professional soldier as a father, who knows a little about high-performance explosives.

For practicality and cost considerations, most bombs today are made of TNT mixed with black gold. However, for some more sophisticated weapons, such as missile warheads, anti-tank charges, rocket propellant additives, and even blasting charges used to detonate nuclear weapons, Oktogen was chosen. As for the one that was developed just the year before, CL-20... more than ten times the power of TNT, and the cost is also comparable, it is very rare to want to promote.

"I think we should find a cover?"

Looking at the small bag in Alice's hand, Wu Mi chuckled lightly: "Even if you say that this thing is stable, but the dirt in Bengfei doesn't recognize people, I don't want to take a bath right away."

"Anna~"

It's strange to be able to care about it, Alice just put the small bag on a clearing.

This is also to show the power of explosives to the greatest extent. Pure natural mud soil can be much looser than the urban environment, and there is no need to dig deep holes, just detonate directly on the surface. Quickly set the time, and then Alice quickly ran towards Miya.

"I set it up for a minute, and run to a hundred meters away~"

Wu Mi walked slowly. The person who sets the time needs to run far, but she would have stayed eight or ninety meters away. Fortunately, the area of ​​this vacant lot is not small, so I walked a distance of two hundred meters in one breath without worrying about the shoes getting wet by the grass branches and dew.

Then, it was the moment when it was about to explode.

Alice stood beside her with a smile, reading the countdown every word.

"Eight!"

"Seven!"

"six!"

"Fives!"

Wu Mi calmly looked at the small bag in the distance, of course she would not be scared by the timing explosion, no matter what the scale.

"four!"

"three!"

"two!"

"One!"

There was a hum.

A shock wave started from the explosion point and spread to the surroundings. The roar accompanied by a huge amount of soil was lifted up, as if a small mushroom cloud was born at this moment. The ground shaking more than two hundred meters away, in a moment, the shock wave has spread to dozens of meters away, and a violent wind blows wildly in all directions. Wu Mi's short hair was flying, she squinted her eyes and observed that the grass a hundred meters behind her was bent by the wind.

"Wow~"

Alice was standing beside her, pinching her waist with her hands, she looked so majestic, her long hair fluttering and not scattered, she was really good hair quality.

"Alice~!?"

The explosion soon stopped, but Wu Mi was a little uncomfortable: "All the shock waves are coming out? You always explain to me how much medicine is in that bag just now!?"

With that said, she didn't forget to look at the pile in the back corner.

For the experiment, Alice came with a small cart on which a full twenty brick-sized custom bomb assemblies were stacked. Wu Mi didn't even touch it, but looking like that, a bag weighs at most a pound, right? But this explosive power...

The smoke disappeared quickly, and the result was placed in front of her, so she ran over without waiting for Alice to answer.

It was a big pit with a diameter of six meters. After all, it was an open-ground surface detonation, so the depth was not too exaggerated, and the **** was also very gentle. Standing at the edge of the pit, Wu Mi knew at a glance that the area of ​​the pit was more than enough to fit four extension Lincolns, and maybe he could lay down five or six Harley motorcycles!

"Yo~Mumi~"

At this time, Alice ran forward unhurriedly, with a triumphant expression on her face: "Guess yourself, how much medicine is in my bag?"

After removing the timing device and fuze for a brick-sized explosives bag, how much is the total warhead charge?

Of course, there is no lower limit to this question, because of course it is about pretending to be as much as you like. Moreover, Wu Mi Ke had seen the explosive deity in the laboratory. It was a crystal-like transparent crystal with a density similar to that of crystal. Even if it was filled with a whole package of turning heads, where could it be heavy?

"let me guess……"

Staring at the big hole in front of her, Wu Mi grinned.

An explosion of one kilogram of TNT can theoretically generate 4.2 million joules of energy. According to 1 joule = 0.102 kg/m, the energy released by one kilogram of TNT can move a one kilogram object by 420 kilometers, or a 100 kilogram object by 4.2 million joules. Kilometers.

The explosives used in modern army grenades are also made of this cheap and stable TNT. The charge of a grenade is about 50 grams. After the explosion, exposed targets within 10 meters cannot survive. One kilogram of TNT is equivalent to 200 grenades exploding at the same time.

The West Point Military Academy even gave a demonstration to the students. The instructor placed 1 ton of TNT on the loess ground. As a result, a full 37 cubic meters of pit was exploded, and the glass windows set two hundred meters away were all shattered.

To say that the explosion demonstrated by Alice was one kilogram of TNT...

The charge of a 76mm high-explosive shell is about one kilogram, which can turn a small house on the second floor into rubble.

Looking at the six-meter-diameter pit, at least one pound is more than enough.

"...Three hundred grams?"

Thinking that this was a new type of explosive specially developed by Alice after all, Mai Mi immediately gave a quota no less than Hexogen.

"Three hundred grams!?"

However, Alice held her hands together: "Three hundred grams is the same grade as Hexogen, right? Mai Mi, are you questioning my ability?"

Wu Mi was impatient, and returned directly to the source: "You can tell me how many grams, so I won't open one of the bags myself..."

"One hundred grams!"

Then, Wu Mi really stopped.

Then she turned her head, her eyes widened: "Fifty grams...Alice, are you sure?"

Of course, this is not a joke, Wu Mi really couldn't help but picked up a dynamite bag with her own hands. Sure enough, the size and weight of the bricks were very light, and she skillfully removed all the packaging, and then found such a small package of transparent crystals in the core part.

Like broken crystals, it's slightly overturned, and it really looks like fifty grams.

The explosion heat of TNT is about 4560KJ/Kg, and the detonation velocity is 6920m/s. Roxykin is about 1.3 times this data. Furthermore, according to Muya's knowledge, the new high-explosive octogen seems to be a kind of white granular crystal. Its explosive heat is as high as 5673KJ/Kg and its explosive velocity is about 9110m/s.

The broken crystal of Alice is much fiercer than Octo today.

"Alice." Mai Mi rubbed her temples and said: "You tell me about its composition process again. I didn't remember it carefully in the laboratory just now."

"Decompose heavy water, that is, deuterium oxide, and organically combine with nitrogen, oxygen and carbon to form an octagonal stable molecular chain. Stable and not easy to explode, and hydrogen isotopes are all substances with low molecular mass and high unit energy. It is also suitable for the detonation part...yes, the detonation part at the molecular level focuses on the final explosion effect from the micro level."

That is to say, the basic principles of bombs are applied to the molecular level. After all, Mai Mi is not a high-ranking student in the chemistry department. She can't fully understand what this means, but everything else sounds great.

Looking at the "fragmented crystals" in her hands, she said: "So what about the manufacturing cost? Heavy water is easy to get. Just electrolyze the water. But I have also seen those messy devices in your laboratory that decompose deuterium oxide. It is organically combined with nitrogen, oxygen and carbon, and what octagonal structure, will the cost be very high?"

Alice's soft laughter sounded behind.

"Don’t you tell me about the raw materials yourself? I electrolyzed water into heavy water and then decomposes it. There are liquid nitrogen and liquid oxygen tanks everywhere, and carbon can be extracted directly from graphite. It can’t be cheap anymore. Eh!"

"So..."

"So, any high school chemistry teacher can try to refine methamphetamine, but unless the basic chemistry is studied to the Nobel level, no one can even try to refine 99% purity."

Alice triumphantly took the explosive from Mai Ya~www.readwn.com~ She still needs to wrap the explosive package again.

"This is a pure process problem, more precisely, it is a problem of experimental procedures. It is a very basic and very basic field, but it can test the level the most."

"It's like you soldiers learn the art of catching, they are all so simple punches, but the ones who get knocked down are always recruits. Is the cost very high? The cost is not high at all, and the process is very simple, but it's just that I can knock you down with this punch, but your punch is crooked by me."

With these words in her mouth, what Alice thought in her mind was the battle of Juxianzhuang in "Tianlong Ba Bu". Aunt Qiao Feng's set of Taizu Changquan, how many heroes and heroes were all looking for teeth, this is a typical example.

Sure enough, even Wu Mi nodded.

"I don't understand pure chemistry, but if you want to talk about grappling, this is indeed the truth."

Seeing Alice preparing for the second demonstration, she chuckled: "It's different from the time when I just went to West Point. I see a rookie coming here, and I can knock him down with one move!" Please browse and read for a better reading experience.
