Later that evening, feeling mildly pleased with myself for actually getting a voltage I though, "lets see what voltage a "spit cell" (a spit soaked wad of paper between two different coins) makes. That's when I felt depressed about my wasted hour, because then I made a voltage of 0.28 in about 20 seconds. This is what I made the next day:
voltaic piles, same idea as a spit cell except multiplied a couple times over. This one also took me about an hour, and again I felt depressed that I'd wasted a lot of time because this puppy cranked only 0.5 volts at maximum. In hind sight, I've learned a lot. And gained a new appreciation for the batteries re-charging on my wall, powering my phone, laptop, electric shaver, wireless headphones, car starter, remotes... it's impressive.
