Glow in the dark paint for styrofoam balls
I made a Zelda-style fairy (as seen in this guide https://www.instructables.com/id/Zelda-Style-Fairy-In-A-Bottle/). I was thinking that I might be able to give the styrofoam ball a little more character when not lit up if I could give it a light coat of paint. If there's a glow in the dark paint I can use for this, even better. I don't want to add so much paint that it will smother the light when it's switched on.
I know spray paint will melt styrofoam, so that's out. Would I be able to sort of dry-brush acrylic paint used for miniatures onto it? I have a few pots of Citadel paint on hand, or I can always run to the craft store. Heck would food coloring work?
Or is the whole idea more trouble than it's worth?
Thanks for any help
