It's getting closer, but I'm having trouble getting the central core of the
spark to connect to the terminals, regardless of what size I scale the large
spark to.

The distance between the terminals is 24, so I'm already oversized here.

//The tight core, purple-white
#declare Discharge_Spark = object { cylinder { <-2,0,-13>, <2,0,13>, 1}
