Action or a game walk on hot coals without injury is often seen. There are allegations of people who do that using magic because the body does not burn walking on fire.
But there is a scientific explanation of why a person could walk on coals without burning?
The first, most of the action goes on fire use traditional fire originating from the pieces of wood.
Pieces of wood are composed of many carbon compounds, some volatile organic molecules, including water evaporate.
These organic molecules would be easy to evaporate when heated, due to the heat released by the fire will vaporize any volatile organic compounds (volatile) and also water. Thus obtained only a nearly pure carbon compounds and carbon is one of the lighter elements.
Structure of lightweight carbon is a poor conductor of heat, so it takes a relatively long time to transfer heat from the coals to one's skin.
But if coal is produced from metal, then heat transfer will occur in real time and someone will get severe burns.
Second, the ash produced from combustion processes can also act as a thermal barrier or insulator layer, so that heat transfer to a person's skin will become slower.
Not that it is impossible burn at all, because the heat transfer can still occur. If someone stood on the coals for some time, then the person will get a pretty serious burns.
But if someone is limiting skin contact with hot coals for example, in a very short period of time or walk quickly, then the legs will not get hot enough to burn skin.
That is why the actions of walking on fire does not make someone burn. But it's not easy to do and it takes a certain expertise.
The burn itself will occur when the body exposed to a substance of high temperature and one of the major causes of burn accidents are exposed to fire.
Based on the degree of tissue damage, so burns can be divided into three types, namely:
First-degree burns, which damage the lining of the epidermis which is characterized by mild swelling in the area, redness and blisters.
Second-degree burns, which covers damage to the epidermis and some dermis (deeper skin layers), arises a sense of pain, infection and sometimes dehydration.
Third-degree burns, which covers damage to all layers of the dermis, the layer of muscle and bone as well as infection.
