Gather Materials

Start with a bowl of clean, room temperature water. Gather your supplies and have all of your ​nail polish nearby and open. Once you start, you’ll need to work fast so that the nail polish doesn’t dry out too soon. It is recommended to read thoroughly through all the steps before beginning the project.

Supplies Needed

Clear plastic cell phone caseNail polish in three different shadesA large bowl filled with waterToothpick or paintbrush

Add Color

Choose your first polish color. 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 (any higher and the polish will sink to the bottom). You’ll notice that the polish will start to spread once it hits the water.

Layer More Color

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. Spread them around the surface of the water at random. They should start to swirl around each other a bit.

Create a Marbled Effect

Use a toothpick or the handle tip of a small paintbrush to gently swirl the polish around a bit more, creating a marbled effect on the top of the water.

Dip the Case

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. You shouldn’t need to fully submerge the case in the water.

Let It Dry

Once the case is fully covered in the marbled polish, remove from the water and let it set out to dry. You may need to gently massage out any water droplets that got caught under the nail polish. If this is the case, just lightly press on the areas with water and work the water out toward the edge of the marbling.
