Black Holes are probably one of the most exciting and misunderstood phenomena in the universe. First off, whoever came up with the name should have slept on the idea for a night or two because they really aren't holes. They're just the opposite. Maybe Mega-Masses would have been better and more accurate. And there are big ones and little ones, ones the size of a million suns, and some that would fit in the trunk of your car...briefly.
Anyway...this fountain is shown here with the optional LED back-lighting, which adds a bit of dimension and magic.
