Add blueberries, soda, and blue dye in a blender and blend them to get the blue layer cup. Then put it in a glass jar.
Add the raspberry, banana, and milk into the blender. Blend the mixture till smooth, then put the mixture in a separate glass jar. This mixture will give you a red color.
Put the ice-cream Frappuccino and ice in a blender and blend them until they mix well; put in a glass jar (this will give you the white mixture)
Into a glass, put ¼ of the blue mixture, followed by a white mixture, and top it with the red mixture.
Serve while fresh, and enjoy!
