The process of making Kong Ming lanterns!!!!! Process!!!!!

Check the material: any paper can be used as a material for making Kong Ming lanterns, but it is best to choose materials that are denser, lighter and not easy to catch fire. For example:

Translucent paper. 2. Design concept (drawing a rough design three-dimensional diagram): The design concept must take into account the position of the center of gravity of the sphere

Try to avoid the design of the center of gravity deviating from the vertical center line, so as not to cause the ignition source to burn to the sphere during liftoff. 2 Appearance, beauty, surface finishing: If the shape design is asymmetrical, it is necessary to pay attention to the position of the fire source and the center of gravity.

3.Weight of the sphere and the size of the fire source: The weight of the sphere is related to the lift force, and the size of the lift force determines the temperature of the air heated by the ignition source and the size of the sphere.

It is not suitable for the sphere to be too heavy and the fire source to be too small. 3. Manufacturing procedures: 1

Calculate the volume of the lamp body and calculate the size of the division. 2 Use these dimensions to cut the sample in thick cardboard. 3. Use the sample to cut the skin.

4 Bonding: (1) There are two kinds of bonding methods: (a) Overlapping bonding method:

After gluing, the adhesive will protrude from the surface of the ball. (b) After gluing, the adhesive is flat to the spherical surface. (2) Bonding steps:

a) First take two pieces as a unit and glue them. (b) Repeat the bonding step in (a) until the shape is completed. 5.

Install the lamp source: Stick the base of the lamp body with thin iron wire or thick cardboard, and install the fuel drum made of aluminum foil or lighter aluminum cans on the base.

The tutorial on how to make Kong Ming lanterns is as follows:Tools: heating guns, straws, small candles, large plastics.

1. Use a heating gun to heat in the middle of the scrapped straw, and paste another sue rock straw with a cross.

2. Then find a few small candles and use a heating gun to heat the bottom of the small candles.

3. Stick a candle on the freshly made straw until it melts, and the distance should be the same.

4. Fix the prepared large plastic bag on the four suction ports of the straw with a buckle, and light the small candle on the straw to burn the slag, and a Kong Ming lamp can be completed.

5. Finished products. <>

The tutorial on how to make Kong Ming lanterns is as follows:

1.Cut the 3-4 penitential sails of the birthday candle in half (6-8 in total) and scrape the wax off the head so that each candle has a long wick.

2.Cut the foil into 12x12cm squares.

3.Fold each side of the foil square so that the wax doesn't spill out.

4.Use a match lighter to melt the end of the candle and use the melted wax to glue the candle to the metal foil.

5.Take 3 straw connections (place one inside the other) so that the length of the straw is slightly shorter than the width of the bag.

6.Place a huge straw over the opening of the bag and glue it to the edge of the bag.

7.Place another giant straw vertically on top of the other, cross them in the middle and glue them to the edges, making sure the bag is tight.

8.Stick the aluminum foil with the candle to the center of the straw so that the candle is pointing towards the closed end of the bag.

9.Optionally, if you don't want it to float away, tie the rope to one of the straws.

10.Hold the tip of the bag and light the candle.

11.Once completely filled with hot air, loosen the bag.

The lantern floats because of physics. The use of hot air creates buoyancy that causes the fire to rise. The waxy blue hail candle on the foil heats the air inside the big bag, and this heated air creates lift through buoyancy.

The density of the air inside the bag is lower than that of the air around the bag. The difference in density due to the buoyancy created by the surrounding air causes the lantern to lift from the ground. This follows Archimedes' principle, which states that any object suspended in a fluid is subjected to an upward buoyant force equal to the weight of the fluid displaced by the object.

The principle also applies to objects in the air.

The specific method of simple Kong Ming lantern is as follows:

Tools and materials: plastic bags, straws, lighters, candles.

1. Prepare four straws and connect them in pairs.

2. Fix it into a cross shape with glue, find a few thin candles, and fix them on the straw with glue.

3. Find another plastic bag to fix on the four corners of the straw.

4. Lift the plastic bag and light the candle with a lighter.

Kong Ming lantern, also known as the sky lantern, commonly known as the wishing lantern and the prayer lantern, is an ancient Han handicraft.

In ancient times, Kong Ming lanterns were mostly used for military purposes. Modern people put Kong Ming lanterns, mostly for blessings. Men, women and children write their blessings with their own hands, symbolizing a good harvest and happiness every year.

Kong Ming lanterns are generally cast on major festivals such as the Lantern Festival and the Mid-Autumn Festival.

The drift direction of Kong Ming lantern is uncontrollable, and can only be "resigned to fate". Once the wind force and the direction of the spring are unstable or the fireworks are not properly set off after liftoff, the Kong Ming lantern will directly threaten the safety of aircraft, high-voltage power supply equipment, communication facilities, mountains and forests and various buildings, and pose a great danger to the fire safety on the ground.

Origins

Legend has it that in the fifth dynasty (907 960 AD), there was a Xin Qi Niang, when her husband was fighting in Fujian, she used to use bamboo strips to tie into a square frame, paste paper, make a headlamp, and place burning pine resin on the chassis, and the lamp flew into the sky by hot air to use as a military liaison signal. This kind of pine resin lamp is called Kong Ming lamp in Sichuan. The shape of this lantern resembles the hat worn by Zhuge Liang, hence the name.

Another theory is that it is said to have been invented by Zhuge Liang during the Three Kingdoms. When Zhuge Liang was besieged by Sima Yi in Pingyang, the whole army was helpless, Zhuge Liang came up with a clever plan, calculated the direction of the wind, and ordered someone to bring thousands of pieces of white paper and paste them into countless lanterns;

Then use the upward gravitational pull of the smoke to lift them into the air, small lanterns are raised, and the soldiers in the battalion shout: "Mr. Zhuge is breaking through with a sky lantern!" ”。

Sima Yi actually believed it and led his troops to chase in the direction of the sky lantern, and Zhuge Liang was able to escape. Therefore, later generations called this kind of lantern "Kong Ming lantern".

Modern people put Kong Ming lanterns, mostly for blessings. Men, women and children write their blessings by hand, symbolizing a successful harvest and happiness every year.

Kong Ming lantern, let's make a wish together!

Let's make Kong Ming lanterns during the Mid-Autumn Festival, full of blessings!
