NARRATIVE
            Paper wrapped around a brass rod will not burn because heat is conducted away by the brass. Paper wrapped around a wooden rod will burn because the heat remains at the paper, rather than being conducted. Wrap gummed labels to the brass and wooden rods. When heat is applied to the labels, the paper on the wooden rod burns, the paper on the brass rod does not.
