Lionel ships these Disposable Plastic Graduated Dropper Pipette with new engines which are widely used for feeding birds, etc. I got on the bay and bought a bag of 100 or some such in the 1ml size. Since Mike advises to fill the dropper to about 2/3 of the first line on the 3ml dropper they supply, I figured a 1ml dropper would be perfect. And the 1ml pipette has a longer skinny tip on it that fits right down into most of the smoke fill openings. I think the 100 or so cost me less than $5 with free shipping.
They are what I use.
