Apparently J Naudin of France, (an emminent
experimentalist with many web pages) has been able to
use  pencil lead, (graphite) to produce a stable
plasmoid, ( Ball Lightening?).  He uses  a microwave
and the standard Tesla coil quarterwavelength method
to achieve this. At
http://jlnlabs.imars-dot-com/plasma/gmr/index.htm
he notes the following;
The frequency of the magnetron is 2.45 GHz, its wave
length is l = 12.2 cm, this gives the height of the
1/4 wave microwave antenna : l/4 = 3 cm

This looks like a easily reproducible experiment if
the materials were available.(pyrex glass globe might
be a problem) The page is nicely done.
