What Ah Yuan is depicting is the most old-fashioned popcorn machine, and he has been squatting in front of the old man for a long time in his previous life, and those machine parts are clear in his mind.

Big belly hoist, head screw, big elbow, small elbow, cover, afterburner rod, afterburner tube, cotter pin and rocker, in addition to being able to stand on the furnace fire, two brackets at the front and rear are also required.

The old-fashioned popcorn machine is actually a pressure vessel, and the processing raw materials are generally corn, rice, broad beans, yellow rice and other common grains, add some sugar or a few saccharin, put it in the machine, and cover the machine cover. Use the afterburner rod and afterburner tube to work together, and rotate the head screw to pressurize the cover to facilitate sealing.

Then the popcorn machine is racked to the stand, and the bottom is heated with a strong stove fire, and at the same time, the popcorn machine is turned by shaking the hand to evenly heat and soften the ingredients inside the machine.

Due to the heat, the pressure in the machine slowly rises, and when the required pressure is reached, the heating is stopped, the popcorn machine is twisted to one side, and the machine opening is covered with a sack. The afterburner tube is sleeved on the small elbow, and the small elbow is pulled hard to loosen the buckle of the large elbow, so that under the action of the pressure in the machine, the cover is opened, and the high-temperature and high-pressure gas in the machine is sprayed out together with the processing raw materials. During the injection process, due to the rapid drop in external pressure, the gas inside the grain expands rapidly, and the grain is burst.

You also have to design a sturdy mask, and it's not good to hurt someone when shiyan.

Then draw a thick cotton five-finger glove sewing drawing, which should be big and can be used on the stove at ordinary times.

To make the rice balls in your memory, you still need to boil the sugar juice to stick, so you can ignore it for the time being.

Right now. Ah Yuan couldn't hold back and wanted to go to the blacksmith to make a popcorn machine. this era. Thanks to the blessing of the founding emperor, there has long been a good thing like corn, which is more fragrant than rice flowers, and it will be produced!

Three or two children sat in the movie theater, holding a large container in one hand and throwing a big-flavored popcorn into their mouths with the other, their eyes staring at the screen, and their feet could be pressed on the back of the seat in the front row. If you are lucky enough to have no one in front of you, you can even occasionally lean your legs into the seat and lean comfortably on your back, then enjoy it, there is no general wonder!

called Steward Xu in, arranged for him to find a blacksmith, and specially instructed him to make the protective mask before trying.

Steward Xu then recounted the process of receiving "Mo Bao Zhai", and Scholar Han was really generous, or he didn't think of taking away the valuable things in the shop, and there were a lot of various types of paper left. Even Dongba paper left six sheets.

"The county lord. The shop is good, but the area is small, the space between the two, do a big business shop can't be opened, the paper shop can't be done, the target group is not right, you see? ”

Originally, he was an old housekeeper who played with a black belly in the princess's mansion, but now, when it comes to doing business, it is a set, in fact, the old guy's family is not tight, and people like to use their brains to make money now.

"Let's go around together in the afternoon, at this time, you go and explain the drawings clearly, and then, you have to go to Lord Han's mansion and send - two hundred taels of silver, just say that we can ask for the shop in vain, and those papers must be paid, otherwise, I won't be able to sleep well." Ah Yuan laughed again as he spoke, and when he was in a hurry to deliver the shop, he was scratching all over his body, and he had to give money to be at ease.

Steward Xu took the order and left, the county lord was in the head, he was embarrassed to say, the general ledger of the county lord's mansion was about to be consumed, the surplus of Zhuyang County was invested in the brick kiln factory and paving in Qiyang County, the brick kiln factory and the off-season vegetables in the capital changed hands again, the farm was left, and the chicken and eggs could not be killed to give disaster, the newly zoned field has not been officially taken over, and it is impossible to have a profit in this season. No amount of silver was thrown into it, and not a single sound could be heard!

The tricycle was sold very hard, and the county lord had to think of a way.

On the way, I met the idle moldy old John, and I heard that Steward Xu was going to the ironsmith workshop, so he had to follow him to see and see, anyway, it was within the county lord's mansion, and it was not against the rules.

However, the talent of the county lord could not be stolen by foreigners, the drawings were not shown to John, the blacksmiths were even more stingy, and the parts of the two-wheeled car were reluctant to let John move.

The poor man was very angry, and went directly to Ah Yuan to complain: "I don't want to steal any craft, it's too idle, I'm uncomfortable!" ”

The most spiritual thing is to direct the season of building the skating rink, to be reused and trusted by heroes, and to feel that the air in the county lord's mansion is fresh.

"You bear with me, the big ship is almost built, and it is being repaired over there, and when Jack and the others set off and come back, I estimate that the emperor will be able to believe in your sincerity, and your free life will begin!"

Ah Yuan stood and spoke without backache, and suddenly pointed Old John into an endless wait.

It turns out that men can have a nervous breakdown when they are locked up all the time, and old John began to jump high: "Don't you dream! Those who have never been to the sea understand that if Jack sets out according to your instructions, he may not be able to return home after a year's walk! ”

"What are you kidding? Now that we've figured out the compass, the ship is stronger than your original one, so why can't we get there? "Ah Yuan is in a hurry, if he doesn't play like this, he curses that other people's ideals can't be realized, he has no conscience!

Old John "hehe" smiled strangely: "You help me find something to pass the time, and help me persuade the emperor to give me freedom earlier, and I will tell you weishenme-".

Isn't that easy? There's so much work to do at home!

Ah Yuan patted the table: "The ironware workshop is not suitable for you, don't say it hard, it's not safe for sparks to splash, I will allow you to go to the woodworking workshop as an apprentice, whatever you want, whatever you want, whatever you want, whatever you want, it is not impossible to say a few good words for you." ”

Old John's eyes rolled around a few times, and the figure retreated, and when he reached the door, he stepped out with one foot, and then said: "Go back to us, the wind is not in the right direction now, the wind on the sea is regular, and it will blow for half a year, and it is best to wait for the second half of the year to think about it-".

The wind is not in the right direction? At this time, shipbuilding jishu was restricted, and it could only rely on manual rowing, if it was to go with the wind and grasp the direction, then it would be no problem. If it was a headwind, a hundred and ten sailors would not be able to row far if they were tired.

The glory of ancient Chinese maritime history depends on the progress of ancient Chinese maritime science. In the Tang Dynasty, there were methods for measuring the height and distance of the topography and features in the sea, which had a profound impact on the surveying and mapping of navigation charts in the future. It is said that the earliest use of the compass for sea navigation on Shijie was in the first year of Xuanhe of the Northern Song Dynasty, that is, in 1119 AD, recorded in the book "Pingzhou Can Talk": "The boat master knows geography, watches the stars at night, obscures the sun, and obscurities with the compass." ”

Now, the Great Song Dynasty only has a name that is the same as in history, and during the reign of the founding emperor, he also made great efforts to instill new scientific knowledge in all walks of life, and the current era is still 1088 AD, and the use of the compass has long been advanced by several decades.

In fact, at this time, the Great Song Dynasty not only solved the problem of direction, but also innovated the rudder, such as cutting many holes in the rudder blades to reduce the resistance of water, and the West did not adopt this kind of "open rudder" cargo ship until the 20th century.

Also, a hinge was used under the mast, and the angle of the sail could be adjusted to suit the direction of the wind, and the mast of the ship that John Sr. and his party piloted and thought was the most advanced in Jishu, and the mast could not be moved.

At the stern, a balanced rudder is used, and part of the rudder surface is distributed in front of the rudder post to shorten the distance between the rudder pressure center and the rudder shaft, making it easier and more agile to operate.

Rows of nail caps are exposed on the hull, indicating that the shipbuilding used "nailed tenon" jishu, and old John's ship was only tied with leather strips and ropes.

It should be said that this time to build a merchant ship, it was also a light to occupy the identity of the county lord, so he borrowed the advanced equipment of many official ships and warships.

In addition, Ah Yuan once couldn't sleep at night, repeatedly recalled how the cabin of "Titanic" leaked and died, and came to personally operate the compartment design: use partitions to divide the cabin into several disconnected spaces, once the cabin leaks, it will only be partially affected, and the whole ship will not sink.

After all this preparation, now you're telling me that the wind is not in the right direction? Ah Yuan raised his eyebrows and stomped his feet violently, Old John knew that he was not in a good mood, so he immediately ran away.

This guy did it on purpose!

However, I am too muddy! Just thinking about building the ship and having Jack lead the way, I didn't have to pay attention to the direction of the wind.

When I was in junior high school, I talked about the monsoon in geography class, because the continent and the ocean heat up and cool down differently throughout the year, a wide range of winds between the continent and the ocean, and the wind direction changes regularly with the seasons, is called the monsoon. The phenomenon of opposite wind directions prevails in a wide range of winter and summer seasons with a one-year cycle.

The warm spring day is just right to usher in the warm and humid southeast monsoon.

Ah Yuan squatted on the ground, grabbed a carbon rod and began to draw a map of Shijie, is it really the wrong direction of the wind?

From Hangzhou Bay, the nearest route should be to go southwest, cross the Strait of Malacca, enter the Indian Ocean from the Pacific Ocean, then cross the Red Sea, the Suez Canal, enter the Mediterranean Sea, and then pass through the Strait of Gibraltar, like driving north, you can land safely on the island of England.

Only those who lack the heart and eyes go east against the wind!

The sailing career is still a blank, old John, they actually floated to the Great Song Dynasty It's really amazing, and it's even more rare that they don't know where they are, and what direction they started from, and now they are still relying on that little sailing experience to make fun of themselves, sister can draw a complete shijie map with her hand, can you? Haven't seen it at all? (To be continued......)
