I just had a crazy ass idea... unfortunately one i dont have time to play with yet. Perhaps someone has already tried this already.

I was thinking.. since the smoke tubes sit in the high velocity air flow, couldn't you simply shape a notch cut or tab over an orfice hole about an inch before the nozzle end and the let the high velocity air passing the orfice create a negative pressure on the fluid draw side of the tube that would suck the fluid from the tank? As the fluid passed the orfice it would be pressurized to spray out the nozzle. Does this seem possible...? If this worked alls you would need is a soleniod to stop and start the flow. Perhaps I just invented a pumpless, self pressurized smoke system...? Ha... it may be worth playing with in the kitchen with some straws and a leaf blower..

My wife loves when I use the kitchen for experiments.
