Put Kongming Lantern on your birthday. Can you put it on? What's the moral! I really want to hang Kongming lanterns this year. Please, great gods. We will post it on our birthdays, and how many will be posted when we are old.
Where can I buy Kongming lanterns in Jieyang? Come on, there are great god boutiques and gift shops. The price is not very expensive. I haven't seen any where to sell it. Basically, I still earn more by myself. . If you buy it, the price will be around 10 yuan. . I found a way to make it for you. I hope it's useful to you:) Make a lantern, very ordinary paper, and leave a hole at the bottom. Make a bracket horizontally with copper wire. The support can ensure that candles are placed. Of course, the candle should not be too heavy relative to the lantern, and the diameter of the hole left under the lantern should be larger than the cross-sectional diameter of the candle, so as to ensure that the candle has enough oxygen after burning. All right, it's done, it's done. Now find a wilderness, light a candle from below and lay it flat on the ground. In a minute or two, lanterns will be raised in Ran Ran. Note: the height of the lantern should be higher than the height of the candle to avoid the top cover being lit by the candle; There should be enough air intake space under the lantern, otherwise the candle will be easily extinguished; Of course, we should also pay attention to safety to avoid fire in dry season.
Please accept it, thank you!
Why did you put the Kongming lantern cage? Please, thank you. The principle of Kongming Lantern is the same as that of hot air balloon, which uses the buoyancy of hot air to lift the sphere. But why does hot air float? We can use Archimedes principle to explain that when an object has the same volume as air, but its weight (density) is less than air, it can fly, which is the same as the buoyancy of water. When the air in the ball is heated, due to the expansion of the air, part of the air in the ball will flow out of the ball, making the density of the internal air less than that of the external air, so that the ball filled with hot air will fly. The lift of the hot air balloon can be determined according to the calculation table without any conversion (Figure 1). But you must know the diameter of the paper balloon and the temperature inside and outside the paper balloon (calculated in degrees Celsius). For example, a paper balloon is 2 meters in diameter, the internal temperature of the balloon is 80 degrees, and the external temperature of the balloon is 10 degrees. On the left horizontal axis of the calculation table, we find a point of 80 degrees, and draw a line from this point until it intersects with the extraspherical temperature 10 degrees. Draw a line from left to right from this point until it intersects with the line marking the balloon diameter of 2 meters on the right. Then draw a line down from this newly obtained point and lead it to the semi-horizontal axis on the right side of the chart. In this way, how many grams of lift can be found on the horizontal axis. In our example, the lift is 400 grams. In the budget, the temperature inside the ball can be calculated as 75 degrees above zero, and the temperature outside the ball can be calculated as the average temperature at that time (above zero in summer 15 degrees). Now let's talk about the making method of Kongming Lantern: 1. Selection of materials: Any paper can be used as the material for making Kongming lanterns, but it is best to choose materials with high density, light weight and not easy to catch fire. For example: translucent paper. Second, the design concept (sketch design perspective): The design concept must take into account the position of the center of gravity of 1 sphere: try to avoid the design that the center of gravity deviates from the vertical center line, so as not to make the fire source burn the sphere during the lift-off. 2 Appearance, aesthetics and surface treatment: If the design is asymmetrical, be sure to pay attention to the location of the fire source and the center of gravity. 3. The weight of the sphere and the size of the fire source: the weight of the sphere is related to the lifting force, which determines the temperature of the air heated by the fire source and the size of the sphere. The ball is too heavy and the fire source is too small. 3. Manufacturing procedure: 1. Calculate the volume of the lamp body, and calculate the size of the split expansion 2. Using these unfolded dimensions, cut the template with cardboard. 3 use the template to cut the skin. 4 Bonding: (1) There are two bonding methods: (a) Overlapping bonding method: after bonding, the bonding place will protrude from the ball surface. (b) After bonding, the bonding place is flat on the spherical surface. (2) Bonding step: (a) First, two pieces are bonded. (b) repeating the combining step of (a) until the appearance is finished. 5. Installation of lamp base: A base made of thin iron wire or cardboard is attached to the bottom of the lamp body, and a fuel barrel made of aluminum foil or lighter aluminum can is installed on the base. 6. Test its stability: blow the lamp body with a hair dryer to test its stability and check whether there are holes. 7. Color it. 4. Launch procedure: The manufacturing method of Kongming Lantern is simple, but it is greatly influenced by the venue and weather when it is launched. When the wind is strong, it is easy to blow the lamp body obliquely and burn it out. It's easy to get wet when it rains and can't be released, so it's best to throw it when there is no wind. 1. First, turn on the lamp body and tie the control lines around and at the bottom. 2. Fill the fuel. 3. After ignition, the air inlet should be as low as possible to reduce the loss of hot air, but it should not be too low to avoid the flameout due to insufficient oxygen. At the same time, the surrounding control lines must be straightened. 4. When the temperature of hot gas in the lamp body is enough, slowly loosen the surrounding control lines to keep the lamp body rising steadily. The bottom control line must control the rising speed and height of the lamp body. 5. After the ball is launched, it can control its height and direction through the line, or it can float freely, thus completing the launch.
Can I put Kongming Lantern Cage in Mianyang, Sichuan? Please note that several places, such as forest parks, nature reserves, forest areas, cultural relics protection areas, and some chemical plants, are generally not allowed to be released before 10 at night, and the time period is clearly defined according to regulations.
Where can I buy Kongming lanterns in Heyuan City? Please don't buy Kongming lanterns for the great gods. It has always been stipulated that it is not allowed to put the Kongming lantern cage.
Why do you want to put Kongming lanterns on the Mid-Autumn Festival? Ladies and gentlemen, the 3Q Kongming Lantern, also known as the Sky Lantern, is said to have been invented by Zhu Gekongming (Zhuge Liang) during the Three Kingdoms period. At that time, Zhu Gekongming was besieged by Sima Yi in Yuping, unable to send troops out of the city for help. Kong Ming calculated the wind direction, made a floating paper lantern, tied with the message for help, and then escaped as expected, so later generations called this lantern Kong Ming Lantern. Another way of saying this is that this lantern looks like a hat worn by Zhu Gekongming, hence its name. Modern people put lanterns on Kongming lanterns as a blessing. Handwritten blessings from men, women and children symbolize the bumper harvest and happiness every year. There is no custom of putting lanterns on Mid-Autumn Festival in our local area. Based on the above, I am wondering whether I should express my thoughts and blessings to my distant relatives in this festival of "I miss my relatives more during the festive season".
How to make Kongming lanterns? Sorry, there is no map. I hope you can understand.
1. Kongming lanterns should be made of suitable materials. It's not like the factory is strict with materials when playing. As long as it is not heavy, you can choose, such as (plastic film, rice paper, copy paper, single-sided paper, etc. ). If the Kongming Lantern is made of other heavy materials and can't fly, then make it bigger and prepare it to be more than two meters high, hehe.
2. The shape of Kongming Lantern is preferably cylindrical. There is no other reason, but it is very simple for friends to do it themselves. Don't make it smaller. The diameter of the bottom is about 50-60 cm. The height of Kongming Lantern should not be too low, preferably around 0.9- 1.0 m, otherwise it will easily burn in mid-air, and the flying height and durability will not work.
3. If the Kongming Lantern is made into a cylinder, it will be very simple to bond it. It is best to synthesize a cylindrical Kongming lantern from two large pieces of paper. Remember that the proportion must be symmetrical, otherwise it is easy to swing. In order to facilitate stamping, you can fold the cut top paper into four parts, then fold the cylindrical shape of the Kongming Lantern flat and stick it on the top edge. Another method is not that I don't want to talk about it, but that it is very troublesome to have no map. Glue it firmly.
4. The bottom ring of Kongming Lantern is fixed with bamboo strips or steel wires, with a small iron wire in the middle and a small iron wire wrapped in the middle, leaving two terminals, so that the fuel of Kongming Lantern can be tied.
5. The fuel of Kongming Lantern should not be too heavy. It is most convenient to dye with thick paper (about 3 pieces is enough) and vegetable oil or alcohol. Cut the paper into half palms and remember to dry it.
6. It is best not to hang anything on the bottom ring of the Kongming Lantern, so as not to be too heavy or tilt it.
7. Because the homemade Kongming lanterns have not been professionally treated for fire prevention, remember not to fly above the 2-3 wind to avoid burns. (Selfishness: The lanterns of our Heen Kongming Lantern Factory are professional in fire prevention, and they can be released when the wind force is above 5. Our customers know they won't burn and fall. )
8. Kongming Lantern should be placed in an open environment without obstacles. When flying, the lights must be turned on as much as possible, preferably for two people.
How to make Kongming Lantern (Figure) 1? material
Bamboo stick, white paper, fine iron wire, alcohol, absorbent cotton, paste.
Second, the production method
1. Paste three thin white sheets into a sealed cylinder with a circumference of 225cm and a height of about 90cm.
2. Tie a circle with a circumference of about 220cm with bamboo with a width of 1cm and a thickness of 0. 1cm, and tie two thin wires perpendicular to each other at the bottom.
3. Put the bamboo ring on the bottom of the cylinder as the bottom, so that the edges of the two are close to overlap, and stick them with paste.
4. Tie a small circle with bamboo, with a diameter of about 15cm, and wrap absorbent cotton around it as the burning core, and then hang it on the intersection of two iron wires.
Third, fly
On a clear and windless night, one person holds the left and right sides of the lamp bottom, and the other person soaks absorbent cotton with alcohol and lights it until both hands feel that the Kongming Lantern is rising, that is, let go of both hands slowly, and the Kongming Lantern will fly slowly, and the rising height can reach 1000m or so.
I tried, and it worked.
Fourth, about combustion.
Newspapers should be chosen as re-fuel, so that the fuel of Kongming Lantern is not enough to fly.
What is the function of Kongming Lantern in Chibi, Li Xia? Pray for the great gods, the first function: Kongming lanterns move with the wind, revealing the change of wind direction and letting commanders know the change of wind direction. The second function: to boost morale. The light moves with the ship, with the momentum of sea and air marching together, which is very helpful to the morale of the army. The third function: dark scenery, a large group of Kongming lanterns, very beautiful. .........
