Author's Note: How big can hail get (and how is that even possible)?

Apparently, back in medieval Europe, would-be weather modifiers rang church bells and fired cannons into oncoming thunderclouds in their attempts to disrupt oncoming hail. Some skeptical scientists maintain that cloud seeding with silver iodide is little better than those early methods. Not living in a hail-ridden region, I had no idea how destructive this form of precipitation can be. Now that I do, it makes more sense that people throw whatever they can at the sky to stop it, even if those efforts come up short.
