When you wash your hands or rinse off soapy dishes under a running tap, most of the water flows out of the faucet and down the drain without being used. It’s a waste. That’s why a Swedish firm created the Nozzle. This tap atomizes water into a fine most. The result: clean hands and dishes and a 98 percent reduction in water use. “The world’s most extreme water-saving nozzle,” is simply attached to the end of an existing faucet in about 30 seconds.
