Glow in the dark

My glow in the dark finger nails photographed in the dark. A 20 second exposure. The red glow is from my mobile phone.
I'd had this polish on for a few days and it glows like crazy all night. Every time I open my eyes in the night (which is often with 2 kids to keep an ear on) my nails are still glowing away. By day the glow in the dark is clear, it doesn't show at all. I'm wearing it over a lovely pale colour shift gold with red flakies and glitter.
