No, not the fun kind where you plunge into a swimming pool, raising a huge curtain of icy cold chlorinated water to splash down on your soon-to-be-ex-friends who were toasting nicely on their dry towels.
This is the kind of cannonball that gets launched from a cannon (imagine that). It seems that a Pennsylvania history buff accidentally fired a two-pound iron ball through a neighbor’s wall 400 yards away while he was testing a French and Indian War replica he had built. Friends, that’s the length of four football fields! Apparently the round ricocheted off the cannoneer’s lawn and smashed through the neighbor’s window before landing in a closet. Ooops!
(Fortunately no one was injured…)
