Hi to all . I was playing with my new laser from Daguin (really good product 150 mw blue ray with flex drive) when i discover that if you point it at a plain paper with some writhing on it with a highlighter the hall think starts to glow like . The glow was so strong that it light up the paper in an very bright orange colour the paper was glowing not only from the site where i was pointing the light but from the opposite side too.
