Poured me some resin yesterday, opaque yellow and blue. Wanted to make a tube caller. Added something to the resin, so I won't lose it before the dawn. Next time I am going to pull vacuum on the resin while it is drying to get rid of the air bubbles, but the thing really is bright in the dark. I used blue Glow in the dark photoluminescent pigment powder. This stuff comes in several colors I am going to pick up some green and red and go to town with it. The dark pics are not doing this tube justice, it really glows bright, it will last eight hours once subjected to the sun all day.
