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

[Herbert H Gottlieb <herbgottlieb@JUNO.COM>]

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.
