Conceptualized and designed by Baek Uyeol, the Faucet Buddy brings your boring old sink to the next level. Simply attach it to any standard faucet, turn on the water and the Faucet Buddy will tell you how much water you are using as well as the current temperature via a nifty looking display. You will never get burned again by sink water because the Faucet Buddy actually illuminates flowing water red or blue depending on the current temperature.

The Faucet Buddy concept is actually meant to help you conserve water by telling you how much water is going down the drain but I think geek consumers might actually use more water just to see it in action. This is only a concept for now, but I wouldn’t be surprised to see something very similar hit the market sooner than later.
