No, those sparks are not "discharging through the air"
as mentioned in the quote above.  They are resulting
from a momentary arc that occurs when you pull two
conductors (that were formerly part of an a.c.
circuit) apart.  Usually when I've done that I've seen
pieces of luminescent burning metal (from the arc) fly
out of the outlet.  I think those are the "sparks" you
are refering to...they're quite different than the
sparks you get from say a 12kv NST arcing across the
bottom of a jacob's ladder...and a completely
different animal than the high frequency RF discharges
from your tesla coil.
