A half a kilometer off the west coast of O'ahu, Matthew Solomona is in the midst of an esoteric explanation of why the water is so blue. It has something to do with the Pacific Ocean being a prism that captures and concentrates the wavelengths of all the azure in the visible light spectrum. It's very informative. But really, all we want to do is submerge ourselves in this aquarmarine stuff. So, my wife and I and our 15-year-old daughter grab the snorkel gear provided on the Hawaii Nautical catamaran tour and take the plunge.
