Re: [TCML] Capacitor Conundrum

[David Speck <dave@xxxxxxxxxxxxxxxx>]

Phil,

I've seen the dissected capacitor demonstrated very impressively at Ed 
Wingate's Teslathon.  His uses flat metal plates, and a thin sheet of 
mylar as the dielectric. 

You can pick up the mylar sheet, and if you run your fingers along the 
sides, you can feel a static charge.  Because the sheet is an insulator, 
it would be unlikely that you would totally discharge it by touching a 
small portion of it.
