Remember those commercials back in the 80s of the angry red hot pot that suggests you turn the handle in to avoid burns on small, curious hands? Well, a German company called Hansa has taken a similar cue by designing temperature indicating faucet heads. As the water passes through the faucet, the lining reads the temperature, and an LED emits a corresponding color to represent the water’s temperature. Red is hot, cold is blue, and pink is warm.
