The Poor Little Fishbowl Sink by designer Yan Lu encourages water conservation in a rather unconventional way. Turn on the faucet and the water in the fishbowl drains. Turn off the faucet and the water level returns to normal. No need to worry for the fish, the water will never drain entirely, but hopefully the user is a little more aware of the amount of water being used.
Haha I love this!!
Tho some people will be sure to TRY and drain all the water in the bowl
