The Blue Planet’s Lifeblood: A Finite Flow


The Blue Planet Earth: Science on a Sphere shows views of earth.


"H20 = Life," a new exhibit at the Museum of Natural History, opens with a "cascade" of water in its vaporous state. Like few other substances on earth, water can exist as a solid, liquid and gas at everyday temperatures and pressures.

The exhibition is meant to have a global reach. It will travel to South America, Asia, Australia and other locations in North America. Its objects include a meteorite from Australia (containing 15 percent water), live Southeast Asian mudskippers (fish that carry water in their bodies as they slither onto land), and a display devoted to the environmental impact of the Three Gorges Dam in China.

It is impossible to enter “Water: H2O = Life,” the exhibition opening tomorrow at the
American Museum of Natural History, and not feel excitement at its possibilities. You walk into darkened space where a tumbling aqua-lighted waterfall seems to descend from the ceiling; letters projected on its turbulent surface spell “water” in multiple languages.
