All these are certainly impossible things. Yet they happen, again and again, in all parts of the world. And these events are witnessed by scores of people. Steering a clear course between blind belief and simple skepticism, fortean researcher Ulrich Magin delves into these stories with both a critical eye and a great fascination for the wonders of our world to unravel the many mysteries held by the air, earth, fire, and water.
