Subject: RE: PUPT: Invisible Blue!


>To those interested in Invisible Blue:
We used Invisible Blue on some scenery used in a puppet show. The scene was 
one of mountains. We painted "eyes" directly on the backdrop so that when the 
lights went out and the blacklight was turned on the "eyes" glowed (as animal 
eyes might at night). It worked very well. While it's true that you might know 
where the "eyes" were on the backdrop, the audience didn't notice them at all.
