Its an old post, but did you video these? Seems like they would also make good graphing stories for depth against time, where the line will be curved. I’d video some myself but I don’t have such a wide array of glasses!

Student: “You mean 5.4 isn’t 5 foot 4 inches?”
Teacher: Agh.

I wonder if there’s something similar about surface area. It’s hard to control thicknesses I guess.
