Re: 2 Questions for the experts here
I believe the yellow and violet are reversed. Yellow small, violet smaller, clear smallest.
Brown and red are just higher concentrations of yellow.
Blue/Gray and Green come up for me if I don't make it on the full moon and/or I don't use HOT water.
I am not writing my observations down, so I am saying this from memory. I am a bad, bad scientist and sometimes my hypotheses are way off, or there are factors I have forgotten and/or filed to consider.
So take everything I saw with a grain of salt peter and conduct your own experiments.
As long as you can by those little red lights that cats love to chase you can make your own particle beam and see the particle size changing and beam density changing. I am going out and buy a dozen just as soon as I have the money in case the FDA starts requiring a prescription for cat toys.
