My wife gave birth to a philosopher. If you come up with an experiment I can show my 6-year-old son I’d appreciate it.

Water absorbs red and infrared (and to a lesser extent yellow and orange) better than other frequencies of light and is almost transparent to blue and cyan. White light minus the red looks blue or greenish blue. The more water light passes through, the more noticeable this gets; deeper water even filters out the green leaving only the deep blue. This is why clear seas, especially in the tropics, seem to go from green to turquoise to dark blue as you get farther from shore and more and more of the non-blue wavelengths are absorbed.
