Is there no end to the psychological warfare of the eco-zealots? This gizmo is supposed to teach children about that to save polar bears you must wash your hands in goldfish waste. Or something.

Well here’s a clever way to encourage people to conserve water while they’re washing their hands. As you use the Poor Little Fish Sink, designed by Yan Lu, the water in the fishbowl slowly drains away. So if you use too much the goldfish will meet an untimely demise. According to Yan the “Poor Little Fish basin offers an emotional way to persuade consumers to think about saving water, by making consumption tangible” though I’m sure there are still a lot of people who would value clean hands over the life of a small fish.

It’s actually a con, because although the bowl drains the water is really coming out of a tap and the bowl simply refills from the mains. But TheEye is a keeper of fish, with several large tanks around the casa, so this might make for a talking point addition to one of the bathrooms….but for entirely different reasons to the one intended.
