Actually, the fact that a body of water reflects the "blue sky" and that is the only reason it is blue... is wrong. Common misconception. If you consult a somewhat detailed physics book (or perhaps look in an encyclopedia under "water" or "color" ) you will find that a water molecule, H2O is in fact "colored" blue... ie: white light striking the H2O causes it to emit a "blue" wavelength photon. The reason water doesn't look blue, if it's in a shallow container, is similar to observing tinted glass... if you look through 1 panel of tinted glass... it looks clear, if you look through a stack of 10 panels, it will look colored... (probably brown). Just as one may ask... how many panels of tinted glass do I have to look through before it "looks" brown? A person (ie: myself, or my old grade 12 physics teacher) may wish to ask how deep water must be for it to "look" blue... Of course, the whole matter is complicated by the fact that every body of water we look at, is not completely H2O... Owell...
