this reminds me, i forget the chemical that does it but blue glow pigment is very persistent, its visibility lasts even longer than zinc sulfide

i hope you have fun with this

i believe there is semi-invisible glow pigments too, i seem to recall the blue pigment was nearly white in normal light, so you colud scribe it onto a surface that is normally white and nobody can see it except in the dark or under UV light
