this is really cool. i think i would like to know whether im going to be handling hot or cold water.

everytime i go and wash my hands i always burn my hands because i never know wether the water will be scorching, and its not that simple. i never think about the temperature, so now i can the temperature.

the price is up now for 19.99

hows it work actually, its a series of LED lights that remain blue until the temperature hits 89 degrees F, the light turns red.
