Now that's a good idea --- I'll just have to make sure I don't jab
anyones eyes out on the subway (I'm car-less in Canada). I'm trying
to imagine just how bulky it will be, hmmm --- I should be able to
manage it, I think.


1/8" brass welding rod is soft. If I were you, I'd cut the elements long
enough to turn the ends into little loops, for eye protection.
