Designed by Yonggu Do, Dohyung Kim & Sewon Oh, this faucet allows the user to see exactly how much water is left for usage. I love the concept because it helps reduce the amount of water that's typically wasted. According to Dornob, most faucets can waste up to six liters of water in half of a minute if left unchecked. There's quite a few flaws with this idea, but aesthetically, this design is incredibly sleek and modern, which is exactly what I love. via Source.
