Magnetic nail polish is a great way to experiment with different nail designs. The polish contains iron particles, which can be manipulated using a magnetic tool. It's known as the cat-eye effect, as the results can display a band of concentrated light going across the nail. Simply apply the polish on top of a base coat and hold one or two magnets over the wet polish for 10 seconds. The magnet pulls the iron particles in the polish upward and reveals mesmerizing designs.
