Jun 30, 2026 · 23m
Summary
This episode investigates the phenomenon of spontaneous human combustion, using the infamous case of Mary Reeser as a starting point. The hosts explore historical accounts and scientific explanations, debunking the myth of internal ignition in favor of the "wick effect," where body fat fuels a slow-burning fire. They conclude that while humans don't spontaneously ignite, factors like smoking, alcohol, and immobility can create conditions for such tragic, contained fires.
