What does it mean to drill wood for fire ?

In fact, it is very difficult to drill wood for fire, if you don't believe me, you can drill for me? You're likely spending a lot of money.

's strength, the biggest achievement is to drill the wood into smoke, but it's still not **!

Drilling wood for fire needs to choose very dry, easy-to-burn wood, such as dry elm, dry willow wood, the drilling process is also very long, and next to a lot of dry leaves, dry straw and other flammable substances, once wood.

With a slight spark on the head, the sparks can fall into extremely dry materials and gradually ignite them, resulting in thick smoke.

Finally, there was a fire.

For this reason, drilling wood for fire is a time-consuming and laborious task. Later, people sharpened the copper mirror into a concave shape and used it to gather sunlight and make it ignite the material, and this kind of copper mirror was become"Impotence", which appeared around the time of the Western Zhou Dynasty.

Time limit. However, the restriction of impotence fire is relatively large, and it must have sunlight to achieve fire.

Later, the fire chain was invented, which is made of iron that is prone to iron filings, like a sickle, and in addition to it, it is also equipped with a stone, this stone is called flint, and it is easy to produce sparks when it collides with the fire chain.

There has to be a fire wool, which is a cotton lint that burns easily, and when the fire chain and the stone hit the spark, the fire fire.

When the star falls in the cotton wool, the cotton is quickly ignited, and then how the spark produced by the cotton becomes a fire.

story. It is said that by the Song Dynasty, the fire cotton had been treated with sulfur, and the efficiency of igniting the fire was greatly improved.

Take a piece of wood and drill it into another piece of wood, and the drill will catch fire.

It is to use a long, pointed wood at one end, drill on the other wood to achieve the purpose of friction and heat, and finally make fire!

Drillwood 取火 (zuān mù qǔ huǒ) Explanation: A hardwood stick is rubbed against wood or drilled into it, and a fire is made by rubbing.

Source: "Guan Yinzi Erzhu": "Those who are born in the form are like drilling wood to get fire." ”

Example: He lives a life on an isolated island.

Rub for fire. It shows that a person has a lot of willpower.

Mechanical energy is converted into heat energy!

The principle of drilling wood for fire is friction to generate heat.

The principle is that the hardwood stick rubs against the wood or drills into it, and the invention of drilling wood for fire is in ancient Chinese myths and legends, in ancient times, the area of Shangqiu, Henan Province is a forest, and the Suiren who live in the forest often prey on wild beasts, and often produce sparks when the stones that hit the beasts collide with the mountain stones. Inspired by this, the Fusiliers struck stones against stones, and the resulting sparks ignited the velvet to create fire.

This method of making fire is still used in the countryside of Shangqiu 30 years ago, at that time, there was a saint who was inspired by the spark from the bird pecking at the flint, so he broke off the flint branches, drilled the wood to make fire, he taught this method to people, human beings have since learned to make fire artificially, use fire to bake food, lighting, heating, smelting, etc., human life has entered a new stage, people call this saint Suiren, worship him as "the head of the three emperors".

Drilling wood for fire uses a hardwood stick to rub against the wood or drill into it, and the fire is made by friction. The invention of drilling wood for fire ** in ancient Chinese myths and legends, in ancient times, the area of Shangqiu, Henan Province is a forest, the Suiren who live in the forest, often prey on wild beasts, Suiren found that the stones that hit the beasts often produce sparks when they collide with the mountain stones, so they are inspired from here to hit the stone with stones, and ignite the velvet with the sparks generated, and make fire. He taught this method to the people, and human beings learned to make fire artificially, use the fire to roast food, lighting, heating, smelting, etc., and human life entered a new stage.

Drilling wood for fire is generated according to the principle of frictional heat generation. The wood itself is rough, and when rubbed, the friction is large and generates heat, and the wood itself is flammable, so it will cause fire. The invention of drilling wood for fire is based on the myths and legends of ancient China.

The Suiren clan is the legendary man who invented drilling wood to make fire. How human life evolved from primitive people to clan communes in the early days is also known in ancient China. Legend has it that there are some big names, and these people tend to be both chieftains and inventors.

Most of these legends were imagined by the ancients based on the lives of primitive people in ancient times.

The primitive man's tools are very simple, and there are many fierce beasts around him, and they will be harmed by them anytime and anywhere. Later, they saw birds making nests in the trees, and the wild beasts could not climb up and could not harm them. Primitive man followed the example of a bird and made a nest in a tree, that is, a hut in a tree.

It's much safer that way. Later people called this "Tsugi for the Nest" (nest cháo, that is, bird's nest). Who invented fire?

Of course, everyone figured it out together. But in the legend, it is said that there is a person who taught everyone to do this, and his name is "Youchao".

The earliest primitive people didn't know how to use fire, everything was eaten raw, and eating plant fruits raw was not counted, even the beasts that were brought in were also eaten alive, and even the hair and blood were eaten. Later, the use of fire was invented (traces of fire have been found on the site of Peking Man in Zhoukoudian, indicating that the use of fire was known at that time).

The phenomenon of fire has long existed in nature, volcanic eruptions, and fire; When there is thunder and lightning, there will be ** in the woods. But primitive people began to see fire, and they would not use it, but were terribly afraid. Later, I occasionally picked up a beast that was burned to death by fire, and I took it to taste, and it tasted very fragrant.

After many experiments, people gradually learned to use fire to burn things to eat, and thought of preserving the fire so that it could not be extinguished all year round.

When the frictional heating temperature reaches the ignition point, it is **.

What was the first thing that humans did with fire after discovering that they drilled wood to make fire, I tell you.

Rub the hardwood stick against the wood or drill into it to make a fire.
