It is a usual practice to walk on the burning coal in certain occasions in rural India. But how is it the people are not affected when they walk on the burning coal is an interesting question wondering how? Then read the logic behind this phenomenon.
Generally those people who are willing to walk on the coal wet their feet several times before walking on the burning coal. Hence when they start walking this moisture evaporates and forming a protective thin sheet against burning.
People walk on a protective layer when avoids severe burns on the feet. The persons also complete the process quickly to avoid further damage.
Furthermore coal is a bad conductor of heat when compared to other metals. If we walk on the iron or a steel surface at the same temperature as that of the burning coal the damage would be much higher as the heat transfer is more. Moreover the skin of the human feet is coarser and is made of different texture. This hellps the skin in withstanding heat for a matter few seconds.
