How Papuan Made The Fire, Imitated Of Eagle

When I was a little boy, My grandmother said to me the history about, made the Fire. Circa 1891, ancestors of Papuan observed natural phenomena to the eagle. When the eagle was flying, sometimes the Eagle stop just a moment and makking action. By my language is called “Yige”

 

What is The Meaning of Yige?

Yige is a making action and producing the flash of light ( Sparks). Grandmother Says, They analyze and Imitate an action of bird eagle, and They result in the Fire.

 

Tools and Materials They Need

The energy of a Man

Temperature

Oxygen

clamp of wood

dry grass

Rattan rope

How to they done

They Put the rattan ripe as the main thing at under and dry grass between clamp Of wood, after that a man attracting

Rattan rope uses the energy of a man going to produce the flash of light ( Sparks) and then, give oxygen by blowing until the Fire burn. 

Chemical Composition of Fire

Fire is the result of a chemical reaction, it’s called combustion. At a certain point in the combustion reaction, called the ignition point, flames are produced. Flames are beside the liquid state, gas state, and solid-state. It consists primarily of carbon dioxide, water vapor, oxygen, and nitrogen.

State of Matter of Fire

In a candle flame or small fire, most of the matter in a flame consists of hot gases. A very hot fire releases enough energy to ionize the gaseous atoms, forming the state of matter called plasma. Examples of flames that contain plasma include those produced by plasma torches and the thermite reaction.

Why Fire Is Hot

Fire emits heat and light because the chemical reaction that produces flames is exothermic. In other words, combustion releases more energy than is needed to ignite or sustain it. In order for combustion to occur and flames to form, three things must be present: fuel, oxygen, and energy (usually in the form of heat). Once energy starts the reaction, it continues so long as fuel and oxygen are present.
