Quantum Tap gives you a good reality check on how much water you think you use and the actual. Working on the lines of how syringe works, the tap activates by pulling up a pump action-handle. Scaled markings on the stem of the handle indicate the amount of water that will be released by pulling the handle to a specific correlating height. You can choose how much water you want to use and pull up the handle accordingly. The faucet looks neat and the idea pretty simple; my only concern is soapy hands and a messy tap.
Quantum Tap is a 2011 red dot design concept winner.
