Plastic Bottle Cap NozzlesHere is a way to turn plastic bottle caps into nozzles. You can then use them for paint, batter, cake decorating, etc. Using metal tongs, put cap over low heat for a few seconds while moving it in a circular motion. Quickly get the thin metal or wooden tool and slowly push plastic out through the middle. It will form a point. Cut the ends with scissors and screw them on desired bottles.
