Too lazy to archive-binge, but at the lake house it seems to be implied that the hand has quite a bit of exposed metal.

Sure, but I'd always assumed that they're designed to detect a specific capacitive signature, which is why the styluses you can buy have rubber tips.

They do look for something that's about the same size as a finger (so a narrow piece of metal wouldn't work), but a piece of metal that's the size of a finger would work fine. In fact, just for the hell of it I just tested it with a 1/2" aluminum rod and my cell phone. I'd post a video to prove it, but I'm not sure how to make my cell phone take a video of itself.

I have a stylus with a hard transparent plastic tip.

Oh, that's easy; you just use your other cellphone.
