Abstract
Daniel's paper on the possible thickness of the Glass Sky made the assumption that rainbows are caused by the glass sky and that its thickness can be determined with rainbows. Of course, this assumption can only work if rainbows are not caused by something else. If they are, then the Glass Sky has nothing to do with the rainbows, and Daniel's paper which rests on that assumption must be discarded. Experiments with artificial light shining through fog reveal the true cause of rainbows to be water droplets, not the Glass Sky. Ergo, Daniel's paper resting on this faulty assumption is incorrect here.
Experiment
On July 16, 2009, at Tuula, Estonia, Marko Krusel shone a bright light through some heavy fog at around 2 AM: www.atoptics.co.uk/fz273.htm. Marko did this with a powerful lamp and found a surprising result: an artificial rainbow. To capture this artificial rainbow, Marko used a Canon 350D with a 15s exposure and an 8mm lens.
As one can see, there was even a faint display of the colors of the rainbow. This demonstrates that rainbows caused by the sun are most likely caused by its light passing through water droplets, as was the similar circumstance with Marko's experiment. Thus, rainbows are not caused by a Glass Sky at all.
Summary
Daniel's paper suggests rainbows are caused by a glass sky. However, the white light of the sun passing through water is enough to create rainbows. Such was the case with an artificial experiment done by Marko Krusel. Since rainbows are not caused by any glass sky, Daniel's paper suggesting they are must be discarded.
