Flying Water Rocket"Flying water rockets" may refer to water rockets in various water rocket activities or experiments, which can take off and fly.
Water rockets were also known as air-pressure water-jet rockets and water-propelled rockets. They were toys or experimental devices designed with beverage bottles and air pressure. During production, the rocket's power compartment, arrow body, arrowhead, tail fin, and other parts were made from discarded beverage bottles in daily life. After the production was completed, a certain volume of water was poured in, and then air was pumped into the air with a pump to reach a certain pressure before launching.
The launch principle was to inflate the rocket body that stored part of the water. When the air pressure difference between the inside and outside of the bottle reached a sufficient level, the water rocket body was pushed out by the reverse force of the water pressed out by the high air pressure in the arrow body. Water was equivalent to the fuel in the space rocket. The rocket mass and the pressure in the cabin played a key role in the rocket launch. Other principles could also be used, such as the absorption of water heat by the helium gas when it floated up, which would stimulate the expansion and generate a huge thrust to launch (but this method had certain safety risks).
In some events, such as TikTok Water Rocket Science Day, participants made water rockets and launched them. The event was announced on July 4,2024 and was divided into two stages: online pre-selection and offline exhibition competition. participants could post water rocket videos according to the rules through the TikTok platform to qualify for the offline exhibition competition. During the event, many teenagers and technology enthusiasts successfully launched their own water rockets.

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.

black and white rocket" Black and White Double Demons " was a term with multiple meanings. The specific meaning depended on different cultures and context. In anime, legends, literature, and movies, there were their own black and white twin demons. In the anime series Detective Conan, the Black and White Double Demons referred to the characters Heiji and Kidd. In ancient Chinese legends, the Black and White Double Demons referred to the Black and White Impermanence. They were the messengers responsible for taking away the souls of the dead. In the literary work " Water Margins," the Black and White Double Demons referred to Zhang Shun and Li Kui. In addition, the Black and White Double Demons could also be used to describe two people or things with opposite personalities. In short, the specific meaning of the Black and White Double Demons varied according to the context.
Rocket design principlesThe rocket's design principle mainly included the following aspects:
- The reaction force of force: The rocket was a jet propulsion device that ejected backward at high speed with hot air and used the resulting reaction force to move forward.
- Mass change: During the flight process, the rocket's mass will decrease as the propellant is consumed. It is a variable mass flying body. By continuously reducing its own weight, it could achieve flight.
- inertia: inertia also plays a role in the rocket's flight.
There were also some special rockets, such as water rockets, which used water and air as power. First, he filled the bottle with 1/4 - 1/5 of its capacity with water. Then, he pumped it with a pump to release the spout of the bottle instantly, and it flew out like a rocket. There was also a rocket developed by SpinLaunch. Its principle was like a hammer thrown at a sports meet. It threw the object through the centrifugal force generated by high-speed rotation. Before starting, the rocket was tied to the tip of the suspension arm, and then the air in the launch cabin was sucked dry to form a vacuum to reduce resistance.
