I built a TC to take to my son's elementary school.  I built a wooden
box with a switchgear grade fiberglass top.  The primary was mounted
inside the box (i.e. on one side of the fiberglass, flat spiral), secondary was
mounted on top.  Powering transformer was a 9kV 30mA.  It worked
flawlessly and would provide streamers up to 12" long, was using doorknob
caps (~4.2nF tank capacitance).  All high energy HV was within box and
out of sight.  The unit looked very nice (clean appearance with no primary)
and was somewhat magical to see sparks with no apparent method to
create the energy.
