Shop Class; Monday, First Period [11/12].
"Morning, everyone," Amaya greeted the class with the usual nod, "welcome back. Today, we're going to try something that's apparently a staple for this kind of class at most schools," though is hardly seemed as exciting as some of the other stuff they got themselves into around here, "and that's going to be a potato-powered light bulb."
Zounds, electricity was weird.
"Essentially," Amaya explained, "how this works is that it creates a chemical reaction between the different types of metals we'll be putting into the potato, combined with the juices of the potato itself, actually creates a voltage powerful enough to charge something simple and small like a lightbulb, which is pretty neat, really, and probably something that could be useful if you feel you need a little energy but all you've got is a tuber, some coins, and some nails."
Because that's totally a situation that would happen all the time! So she walked them through the steps of cutting a hole in the potato, wrapping the pennies in copper wire, plopping that into the potato, do the same with a zinc-plated nail, being careful not to let the two different metals touch while inside the potato.
"Add more potatoes for more voltage, connecting the penny wire to the nail wire on another potato. Start with one, and then keep adding more until you're able to get your lightbulb to illuminate. To test it, just wrap the ends of the wires around the base of the bulb to complete the current. If it doesn't light up, you just need more energy, and you can get that by adding more links in the potato energy chain."
Electricity was weird!
"Different sized potatoes will yield different results; you can also use citric fruits, like lemons, to do something like this, and so if anyone also wants to try a lemon lamp, I've got some of those, too, so go for it. We'll have more than enough time to play around with different things. Any questions? If not, we'll just get right to it."

It wasn't a homemade foundry or anything, but using potatoes to power lightbulbs was still kind of fun.

He was also still a little bothered about never having figured out what the hell happened to that knife last night.

What? She said to play around with it, right?
