I was experimenting on my cat last night, CAREFULLY using red, green, and blue
laser pointers to try to determine which she preferred. The results were
inconclusive, as she desperately wanted to attack any color. Anyway, when the
blue laser hit a green leaf of a house plant, i noticed the dot turned RED. It
was pretty cool. Perhaps some of you would verify the observation. There is
a demo where you grind up spinach and make a green solution of chlorophyll and a
bright white light will fluoresce as it passes through. This blue laser on a
green leaf may be easier.
