The cannon may be a toy, but it can hold a 0.50-caliber round and black powder charge. A friend of the boy said they often filled the cannon with black powder and tinfoil cannonballs. But on Monday morning, the boy was looking down the cannon's 6-inch barrel when it discharged. "It was an accident that shouldn't have happened," says the boy's grandmother. "It was just a toy."
