Materials required:
Clear plastic phone case
Nail polish in three different shades
A large bowl filled with water
Conceptualizing DIY
Toothpick or paintbrush
Steps:
Use the nail polish brush to drip a few drops of the color onto the surface of the water. You'll want to work quickly but carefully; drop from just about an inch or so above the surface of the water.
Quickly continue in the same manner with your second and third colors, dripping a few drops of each over the top of the first color.
Use a toothpick to gently swirl the polish around a bit more, creating a marbled effect on the top of the water.
Take your cell phone case and hold it so that the outside of the case is face down toward the surface of the water. Gently touch it to the surface of the water so that the nail polish starts adhering to the case.
Once the case is fully covered in the marbled polish, remove from the water and let it set out to dry.
