Lead wire,

I believe that lead is toxic so perhaps not a good idea?

It is, but we're going to be listening, not tasting. And it would have to be insulated with something. 

Sodium wire on the other hand. Interesting stuff.  I'm still trying to find information on it, too. Any and all, just looking for "what works"

MYLAR??? What about mylar? Got um' on the moon, RIGHT???
Shorts out Highline wires all the time!!!

We used to have a press for making sodium wire, it was used to dry various solvents. It’s pretty soft stuff but worse than that is the fire risk, it’s a trifle combustable itself and generates hydrogen if you get it wet and also enough heat to potentially ignite the hydrogen though not as much a potassium would. Magnesium is a bit less reactive, stable enough to make wheels from for instance, at least when alloyed, but these have a limited life. In wire form you have a relatively large surface area so its reactivity matters more, the bright light it emits when burning is quite impressive.
