People can go on fire

Professor physics David Willey, University of Pittsburgh at Johnstown (USA), who received the award for best teaching this year by the US president, recently instructed students how to walk on fire in surprise and surprise. admiration of many people.

It has been known to organize barefoot walking ceremonies on mystical fire for thousands of years. The fire road of about 10 m or more was burned from coal, the temperature reached about 600 ⁰ C. The Willey Professor set a record on fire at a temperature of about 1,100 ⁰ C.

Professor Willey explained that people could walk on fire without legs being burned because when stepping on coal only a very small amount of heat passed through the foot. He reasoned that the thermal conductivity of wood is low, the ash on burning coal insulates heat from burning coal, so only a little is transmitted through the foot. It is important to keep the pace steady, so that the skin of the feet will not be swollen when traveling on coal. As you walk, one leg goes over the fire, the other is up into the air, so the dead skin under the foot is very fast and protects the foot from getting hot.

Those who have normal health can go on fire - concluded Willey - The problem is that you have the courage to control your feet on fire like walking in the pasture right from the first step or not.
