Gary,

Can you describe your bug zapper coil? That sound like table top fun. Hmm,
my neighbor welds with argon...

I was fortunate to have had access to a large welder's cylinder of argon
(thanks Steve!).  We found a spool of ~1" diameter clear polyethylene
tubing, kind of a continuous thin plastic bag.  I filled a ~5 foot length
with argon, and holding the inflated tube against my very small bug zapper
transformer-powered coil, achieved several foot-long surface arcing along
the interior of the tubing.  It was similar to a plasma globe.  I suspect
that if I had used a higher powered coil, the plastic would have melted.

I also tried filling an aquarium with argon and running the coil in there,
but it didn't seem to do anything special, not sure why.  I'm pretty sure I
let enough gas flow to displace the air.  Based on that, I doubt the smoke
ring trick would work.
