One Liter Faucet Concept Begs You To Conserve

A bit goofy, but I like it.  The concept faucet pictured above holds about one liter of water in the viewing tube.  The idea is that you should be able to use that much water for a good hand and face washing, a great way to visualize conservation.

Once the one liter of water has been used the faucet refills itself, so technically you can use a much as you like but isn't the point.
