The shortage of water is becoming an increasingly severe problem facing the whole world. Faucets are everywhere in our daily life. The Drop Faucet has a tumbler in the shape of a water-drop, which controls the output of water. When the tumbler is swaying left and right, water runs out. When the "Drop" gradually becomes upright, the water flow becomes smaller and smaller. In this way, water could be saved even if someone leaves the tap on.
