The best place to experiment with explosives is not in a room, not to mention that Alice has rented a separate space. Far away from the plain more than 800 meters away from the inter-county expressway and 320 meters away from the institute in a straight line, the www.biquge.info of the pen "Fun" Pavilion has been completely cleaned up. For practical reasons, Alice is of course not only doing the work of pouring concrete floors, but also making space.

"As you can see, this is our main target at the moment. Sandbags, marble, concrete bricks, and many other materials, but I think you'd love to see it in a dirt clearing right now, right?"

Maiya had always been skeptical, and Guy Alice seemed to have taken the situation too simply. Explosives in the form of transparent crystals, which is really unheard of. Judging from the attitude of the developers, this is still a great thing, as if it is many times more powerful than Hesokin.

Of course, Maiya has been studying at West Point for two years, and he has a professional soldier as his father, so he knows a lot about high-performance explosives.

For practical and cost reasons, most bombs today are made of TNT mixed with black sorkin. However, for some more sophisticated weapons, such as missile warheads, anti-tank charges, rocket propellant additives, and even blasting columns used to detonate nuclear weapons, Octotojin will be chosen, as for the CL-20, which was just developed the year before last...... More than ten times the power of TNT, and the cost is also proportional, so it is very difficult to promote it.

"I guess we should find cover, right?"

Looking at the small bag in Alice's hand, Maiya chuckled, "Even if you say that this thing is stable, but the soil that crashes is not recognized, I don't want to take a shower right away." ”

"Ann~"

It's strange that Alice can ignore it, and Alice directly put the small bag in an open space.

This is also to maximize the power of explosives, pure natural soil can be much more relaxed than the urban environment, and there is no need to dig deep pits, or detonate directly on the surface. Set the time quickly, and Alice ran towards Maiya as fast as she could.

"I've set a minute, hurry up and run 100 meters away~"

Maiya walked slowly. The person who sets the time needs to run far, and she would have stayed eighty or ninety meters away. Thanks to the fact that the area of this open space is not small, I walked a distance of 200 meters in one go, and I didn't need to worry about my shoes getting wet with grass and dew.

Then, it was time for the imminent detonation.

Alice stood beside her with a smile on her face, reading the countdown word by word.

"Eight!"

"Seven!"

"Six!"

"Five!"

Maiya calmly looked at the small bag in the distance, she certainly wouldn't be frightened by the timed explosion, no matter what the scale.

"Four!"

"Three!"

"Two!"

"One!"

Buzz.

A shockwave started at the point of the explosion and spread out in all directions. The roar was accompanied by a huge amount of earth being swept away, as if a small mushroom cloud had been born at this moment. The ground shook two hundred meters away, and in a moment, the shock wave had spread dozens of meters away, and a fierce wind was blowing wildly in all directions. Maimi's short hair fluttered, and she squinted her eyes to see that the grass a hundred meters behind her was bent by the strong wind.

"Wow~"

Alice was standing beside her, pinching her waist with both hands, looking so majestic, and her long hair fluttering and not scattered, it was really good hair.

"Alice~!?"

The explosion soon stopped, but Maiya was a little unsettled: "The shock wave has come out? You always tell me, how much charge was in that bag just now!?"

As she spoke, she didn't forget to look at the pile in the corner behind her.

For the experiment, Alice came with a small cart stacked with twenty custom bombs the size of bricks. Maiya didn't touch it, but looking like that, a pack weighed a pound at most, ......right?

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

It's a big pit, six meters in diameter, because it is an open ground level detonation after all, the depth is not too exaggerated, and the slope is also very gentle. Standing at the edge of the pit, Maiya knew at a glance that for the area of this deep pit, it was more than enough to fit four extended Lincolns, and maybe five or six Harley-Davidson motorcycles could be stuffed with them lying flat!

"Yo~Maiya~"

At this time, Alice ran forward unhurriedly, with a proud and happy face: "Guess for yourself, how much medicine is in my bag?"

How much warhead is there in a brick-sized explosive package, after removing the timing device and fuse?

Of course, there is no lower limit to this problem, because of course it is as much as you pretend. And Maiya has seen the explosive deity in the laboratory, the crystal-like transparent crystal, the density is about the same as the crystal, even if it is filled with a whole package the size of a turning head, where can it be heavy?

"Let me guess ......"

Staring at the big pit in front of her, Maiya grinned.

The explosion of one kilogram of TNT can theoretically produce 4.2 million joules of energy, and according to the calculation of 1 joule = 0.102 kg/meter, the energy released by one kilogram of TNT can move a one-kilogram object 420 kilometers, or a 100 kilogram object 4.2 kilometers.

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

West Point even gave demonstrations to cadets. The instructor placed 1 ton of TNT on the loess floor, and as a result, a pit of 37 cubic meters was blown out, and all the glass windows set up 200 meters away were shattered.

To say that the explosion demonstrated by Alice was on the scale of a kilogram of TNT......

A 76-mm high-explosive shell has a charge of about one kilogram and can reduce a small house on the second floor to rubble.

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

“…… Three hundred grams?"

Thinking that this was a new type of explosive specially developed by Alice herself, Maiya immediately gave a quota of no less than Black Sokin after all.

"Three hundred grams!?"

However, Alice hugged her hands: "Three hundred grams is the same grade as Hei Sokin, right?

Maiya was impatient, and returned directly to the way he came: "Just tell me how many grams you have, lest I personally open one of the bags......"

"One hundred grams!"

Then, Maiya froze.

Then she turned around, her eyes wide open: "Fifty grams...... Alice, are you sure?"

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

Like crushed crystal, a little upside down, it is indeed fifty grams.

The detonation heat of TNT is about 4560KJ/Kg, and the detonation velocity is 6920m/s, which is about three times that of this data. In addition, according to Maiya's knowledge, the new high-explosive Octojin seems to be a white granular crystal, and its explosion is as high as about 5673KJ/Kg, and the explosion speed is about 9110m/s.

Alice's broken crystal is much more fierce than Octo's.

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

"Heavy water, i.e. deuterium oxide, is decomposed and organically combined with nitrogen, oxygen and carbon to form an octagonal stable molecular chain. It is stable and not easy to explode, and the isotopes of hydrogen are also substances with small molecular mass and high unit energy, and carbon is also suitable for use as an initiating part...... That's right, the initiation part at the molecular level focuses on the final explosion effect at the microscopic level. ”

That is, the basic principles of the bomb are applied to the molecular level, after all, Maiya is not a high-level student in the Department of Chemistry, and she can't fully understand what this means, but it sounds like something else.

Looking at the "broken crystal piece" in her hand, she said: "What about the manufacturing cost? Heavy water is easy to obtain, as long as the water is electrolyzed, but I have also seen those messy devices in your laboratory, which decompose deuterium oxide and organically combine it with nitrogen, oxygen and carbon, and what kind of octagonal structure, will this cost be very high?"

Alice's soft laughter rang out from behind.

"Didn't you tell me about the raw materials yourself? Electrolysis of water to heavy water and then decomposition, there are liquid nitrogen and liquid oxygen tanks sold everywhere, and carbon can be extracted directly from graphite, which can't be cheaper!"

"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 try to refine it to 99% purity. ”

Alice triumphantly took the explosives from Maiya, and she had to wrap them up again.

"This is a simple process problem, more precisely, a problem of experimental procedures, a very basic and basic field, but the most test level. ”

"Just like you soldiers learn grappling, it's all so simple to punch out, but it's always the recruits who are knocked down. Is the cost very high? The cost is not high at all, and the process is very simple, but it is my punch that can knock you down, but your punch is crooked by me. ”

Saying these things in her mouth, what Alice thought of in her mind was the battle of Juxianzhuang in "Dragon Babu". Aunt Qiao Feng's set of Taizu long fists, how many heroes and heroes have been beaten to find their teeth, this is a typical example.

Sure enough, even Maiya nodded.

"I don't understand pure chemistry, but if you want to talk about grappling, that's exactly what it is. ”

Watching Alice prepare for the second demonstration, she chuckled: "Unlike when I first went to West Point, I can knock him down with one move when I see a rookie coming over now!"
