Hi,


	Instead of connecting the bottom of your secondary coil to 
	earth, why dont you have it arc to the top of your secondary
	coil, just like a bipolar Tesla Coil, you can do this by placing
	piece of stiff wire( some clothe hanger wire will do), connect the
	wire to the bottom part of the secondary and place it some 6-7"
	inches away from the top of your secondary terminal, I`ll try to
	illustrate:



		 __________   .   .
	terminal(__________)./ \./O
		     II           I
         secondary   II           I
                     II           I
                     II           I stiff wire
                 ==========       I
	primary	 ==========       I	
          ________________________I__
		      \_________/

			Connect the bottom of the sec. 
			to the stiff wire.	
	


	I think you can also connect the bottom of the sec. directly to
	the primary but im not really sure, I think this will give you
	a much thicker, whiter arc but there`s a shock hazard with this
	config. 
	! Something we wouldnt want to have on a science fair !
