One Liter Limited

1ℓimit faucet looks more like an elegant test tube inverted on top of a tap. The glass tube holds exactly one liter of water, sufficient for a quick handwash. The theory being that we waste almost six liters of water and use only one, while washing hands. Once the stored one-liter is used up, you have to turn-off the tap till the next one liter fills up the tube. A cumbersome rationing process that will hopefully drive home the point of conservation!
