And you can see how dense the beam through one is in comparison to the other one.
That's what I was trying to tell you earlier. Possibly if the Amber CS was 500 PPM or larger it might make a difference, but the clear cs was 8.5 PPM and the amber one was only 12.5 PPM.
I saw the laser beam on the CS, but in both cases it was just a line through the jar. I couldn't tell one from the other.
