So I have a paper that I sprayed with glow in the dark spray paint. It charges very fast under blu-ray even with small amounts, but doesn't last that long. I've tried it with a 100mw green and it left a faint, but rather visible trace when I moved the laser dot around. I finally got around to trying it with a 50mw red a few days ago to see how it is able to "erase" by diming the paint. Ok so it worked like usuall and just made a black spot in the dark....until I decided to move it across quickly.....instead of dimming it it made a slightly brighter line that faded back after like 30 seconds....like it was charged up. I waited to my eyes adapted and the paper was drained a bit more. I tried it again and it did the same thing. It wasn't red or anything it looked greenish to me. I mean it's only faintly noticeable , but either way this shouldn't be happening...right? I mean it can't just charge it and drain it depending how long it's exposed to the red.(there should be no light at all espically green light since red is above the range to charge it.) I'll see if i can get a pic or vid, but my camera might not be able to pick it up.
