Drain strawberries. Place drained liquid in a saucepan and sprinkle with gelatin. Cook over low heat, stirring constantly, until gelatin dissolves. Mix strawberries, yogurt, and gelatin mixture in a blender until smooth. Place cups on a tray or in a baking pan. Fill with blended mixture and cover cups with a sheet of aluminum foil. Insert stick for each popsicle by making a slit in the foil over the center of each cup. Freeze popsicles until firm. Run warm water on outside of cup to loosen each popsicle from the cup.
