The " Sparkers" that you found are called Tesla coils.
They are available from the following scientific supply companies:
Fisher Scientific Item AJ543504 $150.00
Sargent-Welch Item WLS-30978 $154.02
Science Kit Item 61157-02 $129.00
By the way ... I spent some wonderful months as a grad student
at the University of Arkansas at Fayetteville, not far from you.

Here at Tech we had two 14" handheld "sparkers" (dated 1963) that we
used for electricity demos. They were brown, with a 3" metal tip and
a variable button resistor to adjust the size of the sparks. They
produced a spark that lit a fluorescent lamp. The current was low
enough that we used it to "shock" ourselves painlessly (kind of; it
left tiny red marks that dissapear in 24 hours).
The "sparkers" are dead now. They sound as if they are working but
no sparks are produced. We need to replace them ASAP.
1. What is the correct name for this apparatus?
2. Where could I find a replacement?
I have search the Internet, but without the proper name I have been
unable to find a replacement.
Thanks in advance,
