Hi All,

When working with one of my first coils, I put a clear ("Party Bulb"
stripped of it's color coating) bulb on the coil.  It glowed a pretty
yellow/green and made coil like pictures on the glass.  After shutdown the
glass would glow green for a little while.  A normal frosted bulb would just
glow purple.  A 4" decorator bulb would also make a nice plasma globe with
purple streamers.  I also tried a elongated reading lamp bulb that started
purple and changed to green, similar to above, and then to purple streamers
as the vacuum was compromised.
