With my recent mobility and newly acquired workload I've had little time to prepare as well for the classes with the children as I would have liked. Still, they continue, though at this point I'm not sure the kids would let me stop. Particularly after this most recent lesson.
The initial discussions had centered around what could be considered a functional tool or weapon. The obvious answers were of course given before some of the older students got creative. My personal favorite was 'Logs. You could rig them up in some sort of trap that would crush something between two that swung down from trees on either side of a trail.' Not the most coherent, but certainly a valid response. I asked whether food and drink could be considered a weapon. There were a few gently shaking heads as the others considered it. Most finally agreed that it's presence could be removed as a form of weapon but that generally it in and of itself was poorly suited.
I smiled, pulling out a clear glass bottle that Dresdor had made for me. We were short on glassmakers and he'd had some skill and took up the post for my special project. Next to it I set a small glass, only half a hand high and filled it most of the way with the clear liquid from the bottle.
"Anyone know what this is?"
"Is it booze?"
I nodded. "Aye, it's alcohol, drink, moon-shine. Pick your name for it. But this isn't your normal stuff. Anyone want to take a swig?"
One of the boys, an older son of our brewer stepped forward boldly. "Ah'll take a swig. Nothin' me's ma kin make that ah can't drink." He reached for the bottle. Stopping him I handed him the shot glass and indicated he should face the group. He drunk it slowly as and then all at once as he tried to get it down before the burning took over. He coughed twice and gasped but tried to surpress any other reactions. Small tears came quickly and were quickly wiped away as he shook his head, handing me the glass back. He'd done better than I expected. I tried the stuff myself and could do no more than sip it slowly. It was strong. Distilled alcohol in it's pure* form was not something to be taken lightly.
"Whooooo-wee. That's strong. Ain't got no flavor though. Just bite."
I couldn't fault him there.
"This is pure alcohol. I want to teach you today about a weapon. Keep in mind that fire is a dangerous tool. It cuts both ways and can be used as easily against us as for us. I've got two demonstrations I want to show you. The first is with another mixture, one I wouldn't drink. So, let's head down to a room I've had prepared."
We funneled down to the very bottom of the north tower. It was unused and unoccupied, but I'd had a room specially prepared. There was only one way in and one way out. There were no cracks to speak of and I'd had a door installed that fit so smoothly the room was almost air-tight. A heavy greasing of the doorframe and edges of the door ensured a near-perfect seal. But the door was special. It wasn't the standard stone door. It was thinner, I intended it for a demonstration and it would only be good once. A large stone basin stood in the room filled with an oily mixture and a bucket full of water stood next to it as well as a large bag of sand and a heavy damp blanket. Three more bottles of the purified alcohol stood against the wall with rags stuck in the tops and into the liquid. I brought the only torch and stuck in on a rack on the wall as we entered.
"Now keep in mind this is still food we're talking about. Oil, fat, drink. These things don't mix well with fire."
I set the tub of alcohol/oil ablaze and it quickly took.
"So, first things first. Fire is dangerous. What's the best way you all know of to put out a fire?"
One of the kids raised a hand and quickly spouted off "Water!". The expected response.
"Good. Water works for most cases. Keep in mind it's not always the best thing though. When you put out something very hot with water you get a lot of steam as the water boils. That can be as deadly as the flames if you get too much of it. Anyways, go ahead, here's a bucket. Douse that fire in the tub. Everyone else take a few steps back. Don't want to get splashed."
The girl picked up the bucket and from a few feet away happily threw the water at the fire. Predictably the water hit the burning oil with a sort of hiss, splashing it all over the basin, but the oil quickly settled atop the water and continued. Some of the oil had splashed out and was blazing merrily on the stone next to the basin.
I patted the girl on the shoulder.
"Good job." She looked down at her feet disappointed.
"I mean that. Some fire you can't put out with water, so keep in mind the things fire needs to burn. Air and fuel. We can't go taking away all the oil from the flames but we can take away they air." I grabbed the damp blanket and tossed it over the burning tub, smothering the flames.
"Another way, short of using all our blankets could be to toss dirt on it. Here, you all give it a try."
I passed the bag of sand around letting them each get a handful before I poured a long line of alcohol on the floor from my bottle. When I was ready I tossed a little bit more to connect it with the small patch of burning oil on the floor and with a 'whoosh' the whole thing burst into flame down the line. The children's faces lit up and they went to with a will, emptying their hands and the bag onto the small trail of flame.
"Ok, now for this last demonstration I want you all to stand against the wall as near the door as you can get. You, you and you. I'll need you as volunteers."
I handed each of them a bottle from the floor and went to grab the torch.
"Now, keep in mind that we've only been playing with little fires. Things that can happen when you cook, or maybe hang around the furnaces. Alcohol can do much more though. These three bottles are an example. They're full of the pure alcohol, as soon as they're burning well I want you to toss them against the far wall as hard as you can. We'll all have to leave the room rather quickly after that and we can continue to discuss it in the next room over. All ready?"
A dead silence filled the room as I took the torch and lit the rags sticking out of the bottles. As soon as the fire took I nodded to the three throwers, I'd picked older children to reduce the liklihood of one of them dropping a bottle accidentally, and on my command they threw the bottles towards the far wall some thirty feet away. The silence was only broken by the sound of glass hitting stone and the loud 'whooompwhoompwhoooomp' that followed as three fireballs erupted from where only black obsidian had been moments before. As the room filled with the light of three bonfires we filtered out in silence to the other room sealing the door behind us, the children strangely silent as they took in the massive potential of such fireballs.
We discussed the usefulness of such tactics in combat only briefly, spending more time rather discussing what could be done were such things used against us. Using such a weapon offensively would undoubtedly lead to the need to protect ourselves from such things as well, and as I pointed out, some creatures like fire-imps were known to be able to magically conjure up fireballs to throw at things, and they were equally dangerous as the alcohol-based ones we had made.
The final lesson came after our discussion, and though compared to the fireballs, was somewhat anti-climactic, it still served a useful point. The door was warm to the touch, but not hot, and I gave it an experimental tug before being convinced it would work for my lesson.
I chose the largest of the children and asked him to open the door. He tugged on the handle, and pulled before finally the stone handle gave way to the stress and snapped off in his hand, the door still firmly shut.
"I just wanted you to see this as well. Call it an after-effect of such a fire in an enclosed space. I mentioned earlier that fire needed air to burn, and in burning it heats it up. The room there only had so much air. I've sealed the door and now there is air out here, but very little in there now that it's cooled. That's called a vacuum. The air out here is pushing against the door so hard that even Tun here can't open it."
I smiled.
"But that doesn't mean it can't be opened. It'd be nearly impossible to open just pulling on it. But if we can introduce a flaw in the door, a small crack or dent, it might be sufficient to break the door down."
I picked one of the girls in the class, the daughter of a marksman and one I'd seen playing with a sling before to throw the stone.
She whirled it around her head a few times before letting loose with a snap and the eyes of the class followed it. It struck the door nearly center, and with a massive 'CRACK' the door shuddered and buckled inward, air rushing back into the room with a gentle 'whooosh'.
It was a good lesson, and what child doesn't like to play with fire from time to time. It also served to let them know what to do about combating fire and got them thinking. Almost anything could be a weapon in the right hands. Or rather with the right mind.
((*technically water and alcohol form an azeotropic mixture at roughly a 9:1 alcohol:water ratio. Purification of ethanol after that is extremely difficult and can't really be done on a normal distillation setup. Sorry there's not much actual game-content, but I'm catching up with some other things. Besides, science lessons can be cool. These demonstrations can actually be done in real-life. I've seen a 50-gallon steel drum crushed with nothing but a good vacuum. I haven't used a Molotov cocktail personally, but I have made contact-explosives in small batches for demonstration purposes. Oh, and by the way, I'm a chemist in real-life, hence the geeky stuff.
