In the laboratory of Bakerland Company, Chen Qiang was holding a tennis line in his hand and kept pulling it.

"How is it, it's very good, right? I've tested it. The tennis line I made is worse than the unreal gut line in terms of toughness." Bakerland said enthusiastically.

"I think we can change our name, such as artificial sheep intestinal thread. What do you think?" Chen Qiang asked.

"Artificial goat intestine line? This is a good idea. It sounds much more high-end, and maybe it can be sold at a higher price." Little Beckland nodded.

"Is this a single core and single layer fiber structure?" Chen Qiang asked again.

"You are right, this is done according to your original idea." Bakerland replied.

Traditional tennis lines are made of goat intestine lines. Goat intestine strings are made of goat intestine fibers as thin as hair. After chemical treatment, washing, glue, they are rolled into thicker strings, and then several thicker strings are wrapped into a complete string. Finally, a protective film is applied to the surface.

The sheep intestine line constructed by this craft is a tennis line, which has a "sucking" feeling at the moment of hitting the ball, with a pleasant sound and a stable and fast rebound force. Therefore, even in the future, many professional players will use the sheep intestine line as a tennis line.

The artificial sheep intestine thread is made of plastic, which is slightly inferior to the natural sheep intestine thread in terms of batting feeling, but in terms of waterproofing and lifespan, the artificial sheep intestine thread is much better. What’s more important is that the artificial sheep intestine thread is much cheaper than the natural sheep intestine thread and can be carried out on large-scale industrial production.

Chen Qiang fiddled with the artificial sheep intestinal thread in his hand, and then asked, "Are there any tennis rackets, let me give it a try?"

"It's been done long ago." Little Beckland asked someone to bring a tennis racket and hand it to Chen Qiang. The tennis racket was made of artificial sheep intestine thread. Then the two of them came to the open space outside the laboratory and began to evaluate the effect of artificial sheep intestine thread making tennis rackets on the spot.

After a few beats, Little Beckland couldn't help asking, "How do you feel? Is it a big difference compared to the previous racket?"

Chen Qiang lowered his head and thought: "There is still a clear difference in the feeling of hitting the ball."

Little Beckland immediately took out his pen and notebook, made the way he wanted to record, and said at the same time, "When I was studying, I just copied it according to the physical characteristics of the intestinal thread, but I didn't consider the feeling in actual use. You can tell me what the differences are. I'll record it and see if it can be improved from the manufacturing process."

Chen Qiang thought for a moment and expressed his opinions from the perspective of professional tennis, while Beckland recorded them one by one.

In the future, with the development of the materials industry, artificial sheep intestine line is almost no different from natural sheep intestine line in terms of the feel of hitting the ball. Perhaps only professional players at the Grand Slam level can distinguish between artificial sheep intestine line and natural sheep intestine line. Ordinary tennis players cannot distinguish it at all. The technology in the 1940s was not yet reached this level.

Then Chen Qiang asked again: "Can this natural sheep intestinal thread be carried out on a large scale in industrial production?"

"Of course," Bakerland continued: "In fact, it is not difficult to make this thing. There is a nylon core in the middle and a layer of polyethylene material wrapped on the outside. The process is very simple. If we don't apply for a patent, there are probably many companies that can imitate it."

"Then we must apply for a patent." Chen Qiang said.

Little Beckland nodded and then continued: "But now the supply of raw materials is a problem, and I mainly refer to nylon."

"Is nylon supply insufficient? I said that there are fewer people wearing nylon stockings on the street recently." Chen Qiang said with a smile.

"It's not that there is insufficient supply, but that there is supply control. Nylon is now a controlled strategic material." Bakerland began to explain.

Since the outbreak of the Pacific War, the United States has established a committee dedicated to managing strategic materials, such as steel, rubber, oil, etc., which are all controlled by this committee. At the same time, the production of materials such as weapons, military trucks, aircraft engines, etc. was also coordinated by this committee. From 1939 to 1945, the United States had 187 billion US dollars of strategic materials produced under the overall control of this committee.

In the early days of the war, only strategic resources such as steel and rubber were controlled. As the war progressed, more and more materials and industrial commodities were also included in the control ranks. Household appliances such as refrigerators were also included in the controlled goods because they consumed a lot of steel. For example, radios were also controlled because of their radio wave reception function.

As air combat over the Pacific became more and more intense, nylon became a controlled commodity. In the 1940s, nylon was a high-quality material for parachutes. The strength of nylon fiber was twice as strong as cotton and five times higher than that of wool. Although nylon was not very heat-resistant, when used as parachutes, its strength and toughness were much better than that of cotton parachutes. Therefore, under the control of the US government, the nylon produced had to be limited to supply to the US Air Force to produce parachutes. These parachutes saved the lives of many American pilots.

Air combat at that time was different from modern times. In modern air combat, missiles were locked from a long distance. Once the aircraft was hit by a missile, it would basically explode instantly. The pilot had no chance to parachute and escape. In the air combat during World War II, if the aircraft was shot down, as long as the pilot was not shot, he would have a chance to parachute and escape. Therefore, a parachute is equivalent to the second life of the pilot. Pilots are much more expensive than ordinary soldiers, so the US military naturally has to spend a lot of energy to ensure the safety of the pilot's life. In order to make more pilots survive, nylon must be controlled, and the US Air Force must have a stronger parachute. As for those ladies who love beauty, say goodbye to nylon stockings for the time being!

It is worth mentioning that in addition to parachute ultraviolet, American pilots at that time had another powerful weapon to save their lives, which was the so-called "life-saving belt". This life-saving belt contained gold rings, gold chains, and precious watches. Sometimes they would directly put some US dollars in it. The purpose of putting these valuable things was to allow the pilot to save his life after landing.

If an American pilot is shot down, it will land on land. If you encounter ordinary people, these valuable things can help the pilots; and if you encounter an enemy, these valuable things can also bribe the enemy and let the enemy save the pilot's life. The US Air Force will prepare a registration belt for those pilots who perform missions. Even if the US Air Force does not prepare for the pilots, the pilot will buy some gold rings and gold necklaces and wear them on their own.

In the 21st century, American pilots still have the habit of carrying valuable weapons with them when performing missions. So if you are lucky enough to catch an American pilot, don’t be polite. You can search out the valuable things on him first.

Back to the topic, nylon control has a great impact on ordinary people, especially for women who love beauty. Nylon stockings have become a shortage of goods.

The artificial sheep intestine thread newly developed by Beckland also uses nylon as the main material. After all, nylon has very good toughness and can withstand the force of tennis ball hitting. However, the control of nylon has caused bottlenecks in the production of the artificial sheep intestine thread.

Chen Qiang lowered his head and thought for a long time, suddenly thought of a solution. He asked, "Since nylon can be used as sheep intestinal thread, then there should be no problem using it as a rope, right?"

Little Beckland thought for a while and answered: "Theory is this. The rope is nothing more than woven with multiple cotton threads, so if you use multiple nylon threads, you should be able to braid a rope."

"Then let's try to make a few nylon ropes. Then send samples of the nylon ropes to the US military's procurement department. The US military will definitely need ropes when setting up camps on weekdays, and the field army will also need ropes to climb high grounds. If the rope made of nylon becomes military supplies and we produce them, the military will naturally allocate us the raw materials for nylon. At that time, we will divide the materials a little bit, which will be enough to produce artificial sheep intestinal threads." Chen Qiang said.

"A good idea, maybe you can make a profit in producing ropes for the US military. I'll go and do the experiment immediately to see if I can make nylon ropes!" Little Beckland was obviously an actionist. At this time, he had no intention of paying attention to Chen Qiang, but ran to the laboratory directly."

Looking at the little Beckland's departure back, Chen Qiang shook his head helplessly.

There is definitely no problem with producing ropes in nylon. If you search for "nylon rope" on Taobao, there will be many options.

In the future, nylon ropes will also be widely used. In the 1940s, although material technology was not so developed, nylon ropes still have many advantages compared to traditional material ropes. At least they must be better in terms of wear resistance. I believe the US military will definitely be able to use them.

...

After leaving Little Beckland's laboratory, Chen Qiang returned home.

At this time, Esther was lying on the sofa and reading the script. When she saw Chen Qiang come back, she immediately jumped up from the sofa.

"Dear, MGM sent me a new script, saying it was tailor-made for me, a water opera," Esther said.

"Oh, water opera? This is quite rare." Chen Qiang replied with a smile.

After Hollywood movies entered the audio era, a large number of singing and dancing movies soon appeared, and gradually became the mainstream of Hollywood movies at that time. Many excellent singing and dancing movies had emerged in the 1930s and 1940s. In the early 1950s, due to the maturity of special-art color technology, singing and dancing movies ushered in the most prosperous era. The most representative one is undoubtedly MGM's "Song in the Rain". Many people should have heard the name of this movie even if they have not watched it.

In the late 1950s, the song and dance movies declined. In the 1960s, although there were excellent song and dance movies such as "The West Side Story" and "The Voice of Music", it still could not stop the decline of song and dance movies. In the 1970s, with the development of film special effects, the rise of great directors with extra-tech skills such as George Lucas and Spielberg, song and dance movies were completely marginalized in Hollywood. On the contrary, in Bollywood, India, singing and dancing became the standard for movies when singing and dancing were disagreement.

The reason why the song and dance films declined was that the production of song and dance films was relatively high and grand, and the large number of actors cost a lot of money. On the other hand, the social and cultural background at that time was not suitable for song and dance films. Too many things happened in the United States in the 1970s, the Vietnam War, the Watergate Incident, the oil crisis, the proliferation of liberalism, etc., all made song and dance films so unsociable.

In the era when singing and dancing movies were popular, various types of singing and dancing movies emerged one after another. From the mid-1940s to the mid-1950s, water singing and dancing movies set off a craze. Because the scenes of water singing and dancing are relatively complex and the actors are relatively large, water singing and dancing movies are more expensive and the scenes are larger than ordinary movies. In that era when there were no special effects of movies, water singing and dancing movies were equivalent to special effects blockbusters of that era.

In the future, many of the audiences who go to the cinema to spend money to watch movies are also aimed at special effects. When it comes to how awesome the special effects of this movie is, the plot is not important. Many bad movies will also hype how good the special effects they have in order to attract audiences. They spent hundreds of millions of dollars for the special effects. However, when they walk into the cinema, they all have special effects for 50 cents.

Water singing and dancing movies are special effects blockbusters from the 1940s and 1950s, which attracted audiences very much. Film companies are also rushing to shoot water singing and dancing movies, which has made water singing and dancing movies unprecedented prosperity.

The script Esther received now is a water singing and dancing movie.

Esther was originally a swimmer and had also learned water dance, so it was easy for her to shoot water singing and dancing movies. It is not an exaggeration to say that this kind of movie was specially tailored for her.

Chen Qiang felt that Esther was very interested in the script, so he asked, "What is the name of this movie?"

"The name temporarily set is -ed." Esther replied.

"mr-co? And ed? What's the hell name!" Chen Qiang frowned.

ed is the abbreviation of male dysfunction, which is commonly known as "impulse", so Chen Qiang naturally understood the name of the movie as "Mr. Co is impotence".

"No, no, not mr-co,ed. But mr,-ed means coeducation." Esther explained.

"So that's how it is." Chen Qiang nodded. He felt that he had gained knowledge again, but Chen Qiang still couldn't understand what the name of the movie "mr.co-ed" means.

So Chen Qiang asked, "What kind of story does this movie tell?"

"The movie tells the story of the famous songwriter Steve and swimming coach Caroline falling in love, but broke up because his agent interfered with it. Caroline returned to the girls' school where she used to work in anger. In order to recover her girlfriend, Steve used the loopholes in school rules to study into the girls' school where Caroline worked, and became the only boy in the girls' school. There were many ridiculous stories during the school period, and Steve finally won the beauty." Esther introduced.

"The male composer went to girls' school to pursue his girlfriend. Why does this plot sound so familiar!" Chen Qiang thought of a classic Hollywood movie he had watched that he had been impressed with.

So Chen Qiang casually said: "This plot is interesting. If a man goes to girls' school, then does he need to wear a ballet tutu and dance with the girls in Swan Lake!"

"How did you guess that there would be such a scene?" Esther asked in surprise.

"It's true?" Chen Qiang reached out to grab the script, and then quickly started reading it.

Halfway through this script, Chen Qiang was convinced that the script in Esther's hand was the classic water singing and dancing movie "The Lotus from the Water" that he had watched.
