Reading up on the boston molasses flood nanora, this sounds like an amazing anti siege implementation although it would cost us massive amounts of sugar. Luckily we definitely have a surplus nora! Imagine a force of wall breechers who thought they've found the weak spot of the stronghold walls only to be smothered by a tidal wave of sugary molassses as their battalions are trapped underneath hundreds of thousands of gallons of liquid sugar. Others try to help them but they too are trapped, leaving them exposed and defenseless to archers and taking out dozens of troops nanora!
