This is water marble nail art. get a small container of water, toothpicks, tape, and two or more nail colors. Cover your finger with tape (except the nail) and drop about 5 drops of the colors, alternating between each one. with a toothpick, go from the outside of the circle to the middle. stick your finger in, and keep it in until you gather all the outside nail polish out. Take it out, and voila!
