Mary Reeser (1884–1951) of St. Petersburg, Florida was most likely a victim of the wick effect. It was suspected that she had accidentally ignited herself with a cigarette. The fat which over time had been absorbed by her clothing likely acted as fuel for the fire. At the scene, investigators found melted fat in the rug near Mary's body. An investigation of a 1963 case in Leeds included an experiment with a wick effect. A small porti… WebbSpontaneous combustion incidences increased when sailing ships were replaced by coal-fired steam ships despite the reduction in voyage duration.
