If you find yourself bored someday and want to create a little colorful magic, try this. Get a macro lens, grape juice, gatorade and diet orange drink. The important thing is that the drinks be different colors and different sugar content. The one with the highest sugar content, the heavies liquid, goes in first and then the next heaviest and finally the lightest. The liquids separate in a nice colorful gradient. Using a macro lens right up close to the glass surface, I shot this simply for the fun colors.
