[Phys-L] Re: Looking for electricity demo apparatus

It sounds like you're looking for Tesla coils. I googled "Tesla coil",
and several sites appear to offer Tesla coils for sale.

Hello all:

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,
