I use the end of a plastic ketchup bottle that I bought at walmart for .99 as a funnel... I tub the tubing thru the holes in the bator in my jars and then on the other end (outside the bator) I attach the funnel and a little duck tape, and i can fill it with a cup of water anytime I need. You dont have the duck tape if your tubing is small enough... Make sense?
