Handmade RocketThe following is a method to make a rocket by hand:
1. ** Material preparation **
- Choose an empty 1.5-liter soda bottle as the main body of the rocket. Make sure the bottle is clean and free of residue.
- Prepare an air pump to inflate the rocket.
- The cardboard was used to make the tail of the rocket.
- The tape was used to fix the various parts.
- Matches or lighters (used to ignite solid fuel).
- Safety glasses to protect the eyes to ensure safety.
2. ** Production Steps **
- ** Prepare the rocket body **: The empty plastic bottle is the rocket body.
- ** Making Tail Wing **: You can use three pieces of cardboard of the same width, one of which is slightly longer. He removed the middle part of the first piece of cardboard and turned it into a frame. He cut a strip from both sides of the second piece of cardboard and stuck the cut strip to both sides of the third piece of cardboard. Then, he stuck the first frame. Finally, he inserted the remaining second piece of cardboard and used two rubber bands to bounce them to both sides. Then, he decorated the rocket launcher. The rocket launcher was ready. He could also draw a few rockets and put them in the middle. He could pull them and launch them.
3. ** Propulsion system related (if involved)**
- The propulsion system of a rocket usually consisted of fuel and an oxidiser. Self-made rockets could use solid fuel, such as gunpowder or a mixture of sugar and potash.
It was important to note that self-made rockets were dangerous. Safety must be ensured during the operation and relevant safety regulations must be followed.

Rocket with SpaceshipRockets were used to carry spacecraft called space launch vehicles. Spaceships were space vehicles that could ensure astronauts to perform aerospace missions in outer space and return to the ground. They were single-use return spacecraft. Space launch vehicles could be used as a means of transportation for spacecraft into space. For example, the Long March series of launch vehicles could send Shenzhou series of manned spacecraft and Tianzhou series of cargo spacecraft into space; the Lijian II liquid launch vehicle would undertake the launch mission of the light boat cargo spacecraft.

model rocketModel rockets were made of a single soft material (such as textile, tissue paper, or plastic film) with a length to width ratio of at least 10:1. They were mostly used for indoor experiments and competitions. The largest supplier of rocket model kits was Estes. If he wanted to start from scratch, he needed to first determine the diameter of the rocket engine so that he could fit the "engine cylinder" on the rocket to prevent the engine from pushing up through the rocket. The engine had to be tightly fitted to prevent it from falling off when it rose. It was better to use a second-hand engine in the process. You could also refer to books such as Van Milligan's "Model Rocket Design and Construction" and "69 Simple Science Exposition Items with Model Rockets." You could also check the website of the National Rocket Teachers Association and NASA's website to obtain relevant knowledge. In order to improve the flight performance of the rocket model, the correct design and production of the streamer could be done to increase the resistance of the streamer when it descended and to reduce the weight of the arrow and the streamer. The streamer material can be selected to be light and have a certain hardness, such as gift wrapping paper. The size of the streamer is usually 90 - 110(mm) in width and 900 - 1200 (mm) in length. After the streamer is folded, each fold is ironed with an iron to increase the resistance of the streamer when it descends. In addition, there was a three-stage rocket model in commercial operations, including the concept of first-stage fuel user base, second-stage fuel conversion rate, and third-stage fuel fission layer.

A novel with a rocket launcherI recommend " Quick Penetration Cannon Fodder Counterattack Strategy " by Hongyan Nanfei Hy. This was a sci-fi space novel. It was about Xu Ran being abducted by the system after her death. She used immortality as a condition to go to various worlds as cannon fodder to counterattack. She would encounter all kinds of strange characters. This was a counter-attack and a slacker novel, not a strategy novel. The female lead was super independent and did not rely on men. Although the beginning was white and the ending was rushed, it was a cool novel without a CP.
" The Strongest Female Cannon Fodder " was not bad either. The author was a pretty girl. In a mystery detective novel, the female protagonist Ruoshui was ridiculously strong. She was very funny. The story was short and concise. The first few stories were average, but it was great from the end of the world. The interaction between the system and the female protagonist was very interesting. It was a very happy story.
" Mecha Hurricane " was a space science fiction novel written on the fourth day of the first month. The female protagonist was super strong. In the future where hot-blooded, conspiracies, and wars continued, the female protagonist's combat power was at its peak. The plot was tight, and the ending was rushed but still exciting. The style is tough, and the female protagonist's mecha battle is super cool. Don't miss it if you like female novels.
There was also " The Tsundere Cannon Fodder's Counterattack ", a work by Candle Ghost. The female protagonist was beautiful and inhumane. She shuttled through the story and fought with strange people. She was a growth-type female protagonist with light reasoning, supernatural, and sci-fi elements.
Finally, it was " The Net King: The Annihilator of Lihai University ", a light novel written by the ordinary Bell. The transmigration to the world of the Net King caused a huge change, and it was an interesting derivative of doujinshi.

Carrying Rocket GunsI recommend " The War of Resistance Against Japan ", a military war of resistance written by armored grenades. The protagonist Zhang Wei traveled back in time to 1937 and became an officer, and the story began. Although she was wearing it, it was realistic and not a drama. The author wrote from a carefully chosen angle, with a comparison between the tragic battlefield and the small characters. The disadvantage was that the update was slow. The rating wasn't high, but I personally felt that it was much better than those shocking war dramas. The details of the battle were very realistic.
" Anti-Japanese Iron-Blooded Manic Soldiers ", created by a madman who was not crazy enough. Leng Jian led the new recruits to defend the territory.
" My Kingdom of Money " was written in an urban language by Smiling Big Airplane. The male protagonist, Chen Hui's Rebirth 2014, came with a cheat. Later on, there was money, beauty, and power. The early protagonist was flawed, but later on, it gradually became better.
'Celestial Lord Xuanxiao' was a Xianxia essay written by Lonely Star in Dream. The main character, Liu Yuan, was carrying the immortal book and embarking on the path of immortal cultivation. The system was perfect, the writing style was good, and the ancient style was rich. Although there were a lot of poems, they were very tasteful. They were immortal herbs that were not popular.
" The Legend of the Anti-Japanese Army's Soul " was an anti-Japanese war story written with bullets and soup. The protagonist, Wang Xiaozhuang, was an interesting story of being stubborn and like a jinx.

Handmade Space RocketHere are a few ways to craft a space rocket:
** 1. Simple Water Rocket Creation **
1. ** Material preparation **
- A plastic bottle (a 1.5-liter soda bottle would be the best) would be the main body of the rocket.
- Paper board, used to make the tail.
- The air pump was used to inflate the rocket.
- The tape was used to fix the various parts.
- Matches or lighters (If you use solid fuel to ignite the fuel, you don't need to use water as a propellent, but it may be used in the production of other solid fuel rockets).
- Safety glasses, used to protect the eyes.
2. ** Production Steps **
- [Rocket body preparation: Choose a clean, empty plastic bottle with no residue.]
- Tailwing production: Cut out four identical triangular tailwings from cardboard and stick the tailwings evenly at the bottom of the bottle to ensure that they are symmetrical and firm.
- "Propulsion addition: Add about one-third of the bottle's total capacity of water into the plastic bottle. The water acts as a propelling agent. When the water is ejected, it can produce an upward thrust.
** 2. Making a more complicated soft landing rocket (Part of the materials and steps)**
1. ** Material preparation (Part)**
- Rocket body: 3 PET bottles (3L size, at least one is used to store soda water to withstand high pressure).
- 4x Balsa wood (200 * 25mm).
- 8x screw.
- 1x spray paint.
- 1x rubber band.
- 1x parachute (old parachute may be used, with ropes tied to each end of the cloth).
- 1x PC board (250 * 250mm).
- Electronic part: 4 cable ties, cardboard, 1 bread board, 1x accelerator (like MPU6050, including accelerator and pendulum), 2 Arduino boards (like Arduino nano and Arduino mega), 1x 3.3V voltage regulator (For example, the LM317 variable voltage regulator, if used, requires 1x resistance (390 Ohms), 1x resistance (240 Ohms), 1x servo-motor (for example, SG90), 2x NRF24L01 + module, 1x battery (for example, power bank, connection circuit board requires 1x USB-A female and male).)
- Tools: Hot melt glue gun, scissors, marker, electric iron, tweezers, measuring tape, staplers, etc.
2. ** Steps (Part-Parachute Making Illustration)**
- After calculating the radius of the bottle, measure the circumference and use the formula [r = c/(2 & pi)]. For example, when the radius is 60 mm, mark two circles with the radius of the bottle minus 1 mm (such as 59 mm) on the cardboard and cut them out.
- Draw a line on each circle, including a line passing through the center of the circle (Line 1), a vertical line (Line 2) measuring 40 mm at one end of Line 1, a point measuring 20 mm at the other end of Line 1, and then draw a dotted line (the length is recorded as L) between the point and the two ends of Line 2.
- According to the L value, a rectangular shape with a height of 110mm and a width of L×4 mm was drawn on the cardboard, and a vertical line was drawn every L mm. The big rectangular shape was cut open and divided into two identical rectangular shapes in the middle. The top layer of the rectangular cardboard was marked for folding, and hot melt glue was applied on one of the circle marking lines and the rectangular cardboard was pasted for reinforcement. The operations such as opening holes for the tie were carried out.
