Wet playing -- someone told me about doing this, maybe Steve Smolian but it could have been Art
Shifrin. They constructed a special "pan" with raised edges less in height than the distance from
the needle to the tonearm. The pan would then keep the fluid somewhat within the space taken up by
the record while the record was spinning, rather than flinging it off the edges. I forgot if they
played the record at full speed or a much slower speed (that would be my guess, given the mess that
78RPM of flying fluid would make). I forgot what they used for wetting fluid, might have been
distilled water or something more exotic.
