"Little One" as we affectionately our youngest daughter loves science experiments. This one she decided to do on her own after seeing something similar in a store. She was comparing regular nail polish to Piggy Paint. The regular nail polish are the blue and a glow in the dark and the Piggy Paint is white. A picture is worth 1000 words. Science experiments like this have such application. It made me want to go out and buy Piggy Paint for myself!!
