water rocket competition

"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. "Legend of the Flying Apsaras" is equally exciting.

The following is a video tutorial on how to make a water rocket with a parachute from a coke bottle: 1. ** Creating the engine compartment ** - ** Draw positioning lines **: Take a 1.25L Coke bottle, tear off the packaging paper, and draw four tail positioning lines in the middle of the bottle with a marker. - ** Making Tail Wings **: Take four plastic tags, draw the shape of the tail wings according to a specific shape and cut them out with scissors. After folding them, stick double-sided tape inside the tags. - ** Assembly **: fix the tail along the positioning line outside the bottle with double-sided tape according to the specified direction, and then fix both ends of the tail with electrical tape. 2. ** Making parachute cabins ** - ** Cutting Coke Bottle **: Take another 1.25L Coke bottle and cut off the head and tail of the bottle as shown in the picture. Make sure that the head can just catch the tail and ensure that the head can slide off when tilted. - ** Making rocket head **: Take a transparent file, cut a circle with a diameter of 20cm with a compass knife, divide the circle into three equal parts, and take one of them and glue it into a cone shape with electrical tape. - ** Assembly **: Use electrical tape to fix the finished arrowhead to the top of the umbrella cabin to complete its structure. Take another 60cm length of the yarn, one end of it is stuck at the joint between the engine compartment and the bottom of the umbrella compartment and fixed with electrical tape. The other end of the rope passed through the bottle of Coke inside the arrowhead and locked the lid to secure the rope. After the rocket head was assembled, it was fixed with electrical tape. 3. ** Making parachutes ** - ** Cutting plastic bag **: Take a larger and better quality plastic bag and cut it into an octagonal shape. - ** Parachute Rope installation **: Take eight 45cm long strands of Velon wire, and use electrical tape to stick them to the eight corners of the parachute, then tie the other ends of the ropes together. - ** Fixed parachute **: The parachute rope is fixed in the middle of the parachute cabin's neon rope. Finally, the parts were assembled and beautified. There was also a simple way to make it: first prepare a plastic bottle, fill it with an appropriate amount (such as 3/4) of water, and make a pressurizing plug.(For example, use a nail to punch a red wine cork so that the air pump can pump air and pressure into the rocket through the small hole). Then, fix the bottle on the launch pad and start pumping air. When the air pressure increases to the limit that the cork can withstand, the water rocket will rise into the air. One could also prepare a plastic bottle in advance, which was filled with 3/4 of water. Then, he would aim the Butane gas tank at the plastic bottle mouth and fill the bottle with gas. Then, he would turn the plastic bottle mouth upside down and relax it. A powerful thrust would instantly push the plastic bottle into the sky. He could also choose three bottles, punch holes, and connect them in series to serve as the power compartment. Before take-off, water would be added to the interior and air would be filled at the same time. The moment of launch, the water would spray down, and the rocket would fly through the reaction force.

The following are some of the key points about organizing the Water Margins Hero Image Design Competition: ##1. Study the descriptions of the characters in the original work 1. Song Jiang - Song Jiang's image was often misunderstood. He wasn't a simple black, short, and thin man. In fact, he was "black, short, and fat". He had "plump skin","a tiger's face", and silkworm-like eyebrows and phoenix-like eyes. 2. [Lu Junyi] - Lu Junyi's appearance was not the image of a gentle and refined councilor that the public knew. His facial features were more ferocious. The book described him as "a man with bright eyes, a pair of eyes, eyebrows, and a body nine feet tall like silver." The word "jung" implied big eyes, and his eyebrows matched with his impatient and reckless personality and the nickname of the Jade Kylin. He should have a rough appearance. 3. ** Wu Yong * - Wu Yong's image was easily misunderstood in terms of age. Although he was often painted as a handsome man, in the original novel, his face was white and his beard was long. In ancient times, his beard was only counted as long as his chest. Combined with his relationship with Chao Gai and other factors, he was about 35 or 36 years old. 4. ** Gongsun Sheng ** - In the original work, Gongsun Sheng looked similar to Lu Da,"Slanted eyebrows, a pair of apricot eyes, square mouth, a full beard." He was nine feet tall (about 1.96 meters in modern times) and did not have the elegant appearance of a sage-like man. 5. ** Guan Sheng ** - Guan Sheng only had three strands of beard, which was different from the modern image of Guan Yu. ##2. Take reference from classic paintings 1. ** Mr. Dai Dunbang's painting ** - Dai Dunbang's "Water Margins" album was very suitable for the original work in terms of character design. For example, Li Kui in his works had a masculine and brave image, with muscles full of strength and explosive power. He drew 188 design drawings for the 1994 TV series Water Margins, which included the appearance of the characters, temperament, scene coordination, clothing colors, styles, and many other aspects. The characters he designed were vivid. The lines of his characters were bold and rough. The eyebrows, hair, and expressions of the characters could express their thoughts and express their unique personalities. Moreover, he had been constantly striving for perfection when designing Wu Song's image, and he had designed as many as seven styles. ##3. Competition Rules 1. ** Original ** - The entries must be original works and must not be copied from the existing designs of the Water Margins heroes. If he borrowed some elements from other works, he needed to carry out reasonable innovation and integration to ensure the uniqueness of the work as a whole. 2. ** Understanding and interpretation of the original work ** - The judges would focus on whether the understanding of the hero image of the Water Margins in the works was in line with the spirit of the original work. For example, whether the appearance, personality, identity, and background of the character were accurately reflected in the image design. For example, Lu Zhishen's chivalrous spirit and courage, Li Kui's rugged masculinity, and other personality traits should have corresponding visual presentation in the image design. 3. ** Originality ** - On the basis of following the original work, the contestants were encouraged to be creative. It could be an innovation in the style of the character's clothing, such as combining the traditional Water Margins clothing with modern fashion elements, or it could be a unique design of the character's posture, expression, and other details to make the character more vivid. 4. ** Technique of expression ** - The artwork could be expressed in a variety of ways, such as painting (traditional painting, digital painting, etc.), sculpture, hand-made, etc. Different methods of expression had their own characteristics when presenting the image of the Water Margins hero. The contestants should choose the appropriate method according to their own strengths. ##4. Awards 1. ** First prize ** - It could be set as a cash reward, a professional painting tool set, or an opportunity to exchange and learn with a well-known artist. 2. ** Second and Third Prize ** - The second prize could be a high-quality art book or a limited edition Water Margins collection, and the third prize could be a custom-made souvenir badge or a cultural shirt. 3. ** Excellence Award ** - For some contestants who did not win the first, second or third prize, but whose works had certain characteristics, they could be awarded an excellent prize, a certain certificate of honor, or a small gift. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The 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. The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!

Rockets 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 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.
