I have a box full of glow-in-the-dark stuff There's even an old used toothbrush in there (with the bristles removed, of course).
I used to have it hanging around my room near a light source, but could never find a good way to get it all to stay. Hot glue, staples...it all just came right off. Maybe one of these days I'll have to tie it all to strings and make a mobile.
