Objects crashing down from the heavens apparently has its place in history. Spiders, hard boiled eggs, mice, frogs, crosses, blood, and more have been reported by reliable sources. Villagers in one town in Honduras take out pails each year to collect the fish that fall during the rainy season. Scientists guess why this occurs, but every answer has problems.
It's a fascinating read for your students and children. Even more fascinating might be the stories they create to explain this phenomenon.
