	You're wrong, it's right.  8)>>

	Where on the secondary was it?
	It may be too late to ask: was there previous
	damage to the insulation?

	(insulation may not be able to 'stop' corona,
	it can influence onset.)

	There is much on this in the archives.

	The classroom?  A Trailer?

	Would it be practical to unplug it and put it elsewhere?
	Also, how big is this coil, that affects the precautions.
	I'd run a dedicated power cord, with shortest possible
	dedicated ground for RF portion of coil.

	(I'm guessing grounding of the electric supply is a bit
	indirect, for the trailer.)

	(I get in trouble here with my views on that.... 8)>>:
	I don't think its much good for anything but light
	shows.  Others likely think differently.  (that's my view,
	debating it is likely OT.))

	There are many sites, not sure I'd want to pass judgement
	on which are 'good'.

	Related:
	Should 'we' have a condensed list of demos:
		fluorescent lights
		Same with antennas
		Lighting rod (?)
		remote power (diode small motor)
		ion motor
		???

	Uses:
		Has been used for vacuum system leak checks.
		Has been used for HV source for atom smashing.
	I'd spend some time on Tesla The Man...
