For each freeze, in a blender combine 3 scoops orange sherbet and 1 scoop vanilla ice cream. Add 1/4 liter lemon lime soda or lemon lime seltzer and 4 ice cubes to the blender. Set blender top in place and blend on high setting until frothy and smooth. Pour into fountain or tall glass and garnish glass rim with a round of lime and a straw. Repeat with remaining ingredients.
