I took on a teacher's tone as I began my lecture. "I know I've been saying this word one too many times tonight, but imagine the vats in the Furnace. Those things are leak-proof on top of being sturdy enough to hold molten metal, correct?" The nods all around prompted me to continue. "Now imagine if they were filled with water, then we put it over burning Black Ore. What do you think would happen?"
"Uh... Nothing?" Ruby valiantly answered. "The water wouldn't turn into steam, but I can't see how it can make enough power to rival a rifle."
"Ohh... But what if during this time, a small hole suddenly appeared in the vat?" I sagely pointed out. "All of the steam building up inside the vat has nowhere else to go, and thus...."
I trailed off, hoping that someone would get what I was insinuating. Sure enough, the first person to get it was Lise.
