Turn any faucet in your home into a streaming fantasia of techie-bliss. Just attach to the end of your faucet, and when the water flows through the magic chamber, it simply turns on the LED array and illuminates the stream with soothingly powerful hues.
You get to choose between two different Faucets.
Blue LED - Always streams BLUE LED's
Blue/Red LED - Normally streams BLUE LED's until the water temperature hits 89 degrees after which the LEDs turn RED! Which is the real geeky toy! IMHO.
