My friend Miana dedicated months to turning her dream of glow-in-the-dark tattoos into reality. She started by finding a power source encased in silica, making it water-resistant. The critical factor was that the silica coating should also be body-safe. The original tattoo idea gave way to scarification, which could accept the sand-like powder. I acquired one of these at Grindfest 2025, and although the lines are spotty, the π is perfectly visible and legible.
