This Nails Inc. magnetic nail polish is amazing. The polish itself contains magnetic particles, after you apply it you wave the magnet that's on the top of the polish bottle over the nail and it creates these wavy 3-D images. What? Yes, it's true. The future is now. You can watch this video to get a better idea of what I'm yammering on about. Sold at Sephora. It's $16.00 but I think it's worth it!
