Poor Little Fish Sink
Visualization is always a handy way to teach new concepts and get people to reconsider their habits, which is the idea behind this Poor Little Fish Sink. As you take longer and longer to wash those hands, the fish water appears to get lower and lower. It’ll be a big reminder to shut off that water before it causes any harm. However, thankfully the fish is never actually in danger of running out of water.
It has some hidden plumbing that lets the water drain a bit, up to a point. Then it’ll very slowly fill the tank up again to keep the fish safe from going into shock. Sure, people will eventually figure out that the fish is completely safe and they can wash their hands as long as they like, but it’s a nice reminder for those that are trying to remember to conserve waster. This is a concept design by Yan Lu, so right now it’s not actually up for sale.
