The Turn Of The Century Electrotherapy Museum http://www.electrotherapymuseum.com The Real Use For Brass Bed Balls Many thanks to Steve for sending me these! My "Jackson Coil" reproduction setup with the addition of a static collector for the Phantom Streams. Note the brass Bed Ball! Power supply is to the right. Effluves and phantoms are soft, sparks are harsh The sparks crackle like a static machine Reaching... These sparks turned out great.  The bottom spark (white and jagged) gives a real feel for the static effects. Thanks Steve!! Update:  Evening Some photographs barely showing Phantom Streams
