Why do Thai monks have magical powers?

A monk in Thailand was sitting in an oil pan with a burning fire under it. Onlookers can see that the oil in the pot is tumbling, but the monk is calm and not hurt by it. Some people think it is a kind of "magical power of Buddhism", while Gessa Da, a science lecturer in Chulalongkorn University, Thailand, thinks it is a "trick" to make believers worship or buy amulets. The method of debunking is very simple, as long as the oil temperature is measured with a thermometer at the scene.
