I think you've confused St. Elmo's fire with ball lightning.  St.
Elmo's fire is merely corona discharge, easily demonstrated with a
small HV coil and a sharp object.  Electrons will ``spray'' off the
point of a pin attached to a Tesla coil, for example.  (I have a
four-foot secondary wrapped with AWG30 wire I used to play with...)
