Robin explains, "Take a plastic pop bottle of any size and cut it off about 1- to 2-inches below the neck of the bottle. (It will look like a funnel). Save the bottom of the bottle for another project. You may decorate it or label ownership with a permanent marker. With the lid off, dip the other end (cut edge) of the bottle into bubble solution in a shallow pan and gently blow air through the neck of the bottle. You have an instant bubble blower."
