Here are a few links to demonstrations of the OA dribble. The first is from University of Guelph Honey Bee Research Centre which is a consistently reliable resource. The other two are basically demonstrating the formula and method from Randy Oliver's scientificbeekeeping.com. Each video has value. Jayson of Jaycees bees does a nice job of converting the recipe down to treat a smaller number of hives. Emmy of Emmymade uses small syringes but I think you have better control with the more widely recommended 60cc irrigation type syringe available in farm supply stores or online. Hope this helps!
