So my wife and I have been playing science lately!
I know some people might feel compelled to let me know that the power these batteries generate is too low for anything too practical. But, the thing of it is. We have all this stuff already, and putting them in series is not that hard so...
At any rate, learning to make them has been fun to say the least. I mean, it's garbage, and it's doing stuff, I find that fascinating.
