Even in the ancient Ming Dynasty, with the level mastered by Zhu Zilong, plus a little modern stuff in the past, hydrogen can easily be produced on a large scale.

In the modern 21st century, smaller hydrogen balloons are currently mostly used for children's toys or festive releases. Larger hydrogen balloons are used to float advertising banners, also known as empty floating hydrogen balloons. Meteorologically, hydrogen balloons are used to detect high altitudes, and militarily hydrogen balloons are used to set up communication antennas or distribute leaflets.

It's a versatile cheap all-purpose product!

The only thing to pay attention to when using a hydrogen balloon is that the friction of hydrogen with other objects will produce static electricity and encounter open flames, high temperatures, and electric sparks, which will cause flammable and explosive hydrogen combustion and explosion.

For example, take cartoon hydrogen balloons such as "Pleasant Goat", "Big Big Wolf" and "Bald Strong" on the market as an example.

The gas in the balloon will immediately turn into an "incendiary bomb" when it encounters fire, and the moment the flame touches the balloon, the balloon will spew out a flame one or two meters high, which will burn instantly, and burst out with a pungent smell. During the combustion process, the flames of the balloon are scattered, and there is a small combustion explosiveness!

The world's first hydrogen balloon was born in 1780, when the French chemist Braque poured hydrogen into the bladder of a pig to make the world's first hydrogen balloon.

Of course, pure hydrogen will not explode on its own, so as long as you don't die by yourself and control it well, you are still not afraid.

In my own villa, I did a DIY day.

Zhu Zilong asked the secretaries where the suburban firecracker factory that he bought a few months ago was.

After being brought there, Zhu Zilong drove a large car back on the grounds of checking samples and inspecting them.

The factory was also part-time responsible for part of Zhu Zilong's logistical support when the gunpowder guns of the Ming Dynasty ran out of ammunition. At the same time, it also solves the work problem of some migrant workers in Nanjing!

Zhu Zilong, who returned to the villa, poured pure modern black powder into the tin can.

The inner diameter of the tank is five centimeters, and the wall thickness is less than half a centimeter. The height is five and a half centimeters, and the outside of the mouth of the tank is turned with four or five threads (about half a centimeter in height). The lid of the can is also similar to the can!

A three-millimeter through hole was drilled in the middle of the lid of the can to put the fuse, and the weight of the black powder contained was about 517 grams (fortunately, it was just over a catty, and the density mainly depended on whether the black powder was loose or not).

In other words, the total weight of this big iron cannon is about three to five kilograms!

After making a few samples, Zhu Zilong drove to a no-man's land further away in the suburbs.

The fuse was lit and the explosion was observed behind a dirt slope about 30 meters away.

I only heard a loud bang!

That sound is comparable to ordinary firecrackers, it's a big bomb! The deafening sound was terrifying to hear from a distance of more than thirty meters, and the explosion formed a crater more than half a meter deep and more than three or four feet wide!

Seventeen pieces of various sizes were dug up at the bottom of the pit, and the others were found at a distance of a kilometer or two.

Pierced into the bark of a tree, it takes a lot of force to dig it out, and this will pierce into the human body, and it will definitely hang up a long time ago.

"This modern refined black powder is more than the Ming Dynasty's hanging bombing. The effect is N times stronger! Zhu Zilong felt a chill in his heart, this is much more powerful than a dozen grenades!

Tried to check the information on the Internet, and Zhu Zilong's heart was even more frightened.

It turned out that some video netizens tried it personally. said that if it was replaced with a pound of silver medicine in a firecracker (only to know that it was high chlorine X potassium, and silver X aluminum powder or something), the same weight of the charge, it is estimated that Zhu Zilong stood thirty meters away just now, and he may become a disabled person lying on the ground!

In addition, the old 12-pounder gun of 117 mm caliber had a grenade charge of only 500 grams of black powder.

When he calmed down, Zhu Zilong thought about it.

The modern formula and materials of black powder are indeed interesting enough, but if there is no ignition device, even if the hot air balloon is taken off and brought to the territory of the Qing army. It's really hard to say how many explosions there will be when this falls.

If you make it the same as a grenade, it might work, but the lead is a problem.

These tens of thousands of meters of air fell, I'm afraid most of them were either dumb fires or exploded halfway, right?

Isn't that a waste in vain, and return the samples of explosives to the Qing army to study?

Can't you buy modern real explosives?

If you really go to buy aerial bombs, it is estimated that within a few days, there will be relevant Chinese departments in the 21 st century to check on themselves. So, you can only think for yourself!

Try and try, check and check.

In the end, Zhu Zilong set his sights on fertilizer explosives.

In 2008, the five fishermen of Wenchang were arrested for using 170 catties of chemical fertilizer to make explosives.

According to the police handling the case, Zheng, Cai, and Zhou, who were suspected of illegally manufacturing explosives, were from poor families and all went to sea to fish for a living, but often returned empty. When Zheng heard that chemical fertilizer could be used to make "fertilizer explosives", he decided to take a risk and try it.

He bought a package of about 80 kilograms of fertilizer from Chen at a price of 60 yuan, set up an iron pot in a cottage by the sea, poured fertilizer and diesel fuel to fry nearly 80 kilograms of explosives by himself, and made light yellow granular explosives.

It's just hanging and frying, and the explosives are still fried in the pot. Sweat!

This fertilizer explosive is not sensitive to blows, collisions or friction, but it will explode under extreme conditions of high temperature and high pressure changes and in the presence of substances that can be oxidized, and safety regulations must be strictly observed in production, storage, transportation and use.

When a hot air balloon is dropped from a high altitude, it is a perfect match.

For a while, Zhu Zilong was very happy in his heart.

Fertilizer or something, it's a panacea. Before it is fried into explosives, it is used as nourishment in the field, and it is fried as explosives in wartime.

What a TM cow ratio!

So far, Zhu Zilong's hot air balloon Ming Dynasty copycat ICBM program, all necessities have perfect substitutes and production methods.

In the blink of an eye, he was happy and began to give the newly factory Zheng He Baochuan No. 4. In addition to all kinds of materials and medicines that had to be transported back to the Ming Dynasty, a large barge was added to hang behind, which was full of fertilizer and hydrogen production equipment!

Wait until Zhu Zilong finishes this, and then turn back.

I saw Xiao He driving a car with a strange thing and came over.

Zhu Zilong stepped forward to inquire only to learn that Xiao He saw that Zhu Zilong seemed to want to import and export ceremonial flowers, and for this reason, he also acquired a large suburban firecracker factory (obviously, he misunderstood. ）

No, he also has a friend who is a donkey friend, and Jing Ran is a professional maker of fireworks and fireworks.

Now let him pull a cart of samples over, one gang of bosses, two of friends, and three of them to earn some extra pieces for themselves, which is really a triple win.

Zhu Zilong sighed and patted Xiao He's shoulder, admiring his cleverness. At the same time, he came to his car and glanced at the sample of the salute bomb on the car.

In the next second, Zhu Zilong's brows twitched.

At this moment, Zhu Zilong's heart was like 10,000 divine beasts and mud horses galloping by, thinking: Alas, my numbness, Comrade Xiao He.

Are you sure it's a fireworks? And not a bomb?

This big ball with a diameter of 1.2 meters is really a gift for the festival? -
