I’d also add: a TODO item on my list is to make my own followup question for Expansion of Nothing that presents rings of different materials (i.e. something like a ring of water, a ring of jelly, a ring of concrete, something like that), and asks “in any of these cases, do you get a different answer than the Iron Ring?
I don’t actually know currently whether there exists a material that gets you a different answer, so this is a bit of a research question. Crafting the final question such that it somehow gives you enough information feels like part of the exercise. [by which I meant the meta-exercise of “creating an exercise”, which I think is also a useful thing to learn]
I actually created a doc where people can add their own confusions and answers for Expansion of Nothing: https://docs.google.com/document/d/1cleM-QuO9R9_jRqDZMMKzobpWcf-k9KHBe91fUMWhuQ/edit
I’ll edit it into the OP.
