Okay, maybe not this long:
Builders in the old part of the Canadian city of Quebec have unearthed a live cannonball fired by the British during a siege in 1759.
They posed for photos with the large, 90kg (200lb) projectile, unaware that it was still potentially explosive.
Army bomb disposal experts later collected the device, saying there was still a danger, CBC reports.
Let’s face it, they built bombs better in the old days.
Quebec City archaeologist Serge Rouleau, who examined the munition before the army and noticed that it still contained a charge, said it was more an incendiary bomb than a cannonball, Le Soleil news site (in French) reports.
Finding live ordnance from World War II is not uncommon. Even World War I stuff can still be turned up. But from the French and Indian War? Amazing.
