Are you sure about this? I have found the opposite to be true. If you 
take a neon sign transformer and connect it to an adjustable gap and 
set it just to where a spark can't jump then hold a match several 
inches under the gap a spark will immediately jump the gap and 
continue to arc until the match is removed, then it will stop.
Also if you measure the gap distance and construct a glaas tup with a 
gap of equal length and connect it to the neon sign transformer while 
pummping down the tube again the arc will jump the gap as the air is 
rarefied then continuing to pump out the air it will spread out into 
a purple glow which will get fainter and fainter untill the glow will 
stop and no further conduction will occur.
