i got a couple of nozzles from the end of a soldering gun that i founf laying around and am thinking of trying them! at the mo i had drop size up at way too high (85) thinking bigger drops would give me bigger coloums but gonna go small now and add a few drops of rinse aid to tray and some glycerin to the drop bottle maybe 50/50.
still not got ir, sound or lightning going i just cant get my head around emm at the mo ... maybe i need to put my lucky space invaders tshirt back on 
lol
