A great gift for the home, office or dorm!

This eco-friendly clock is powered by water, and has four functions: Time, Temperature, Countdown Timer, and Alarm. The H20 Multi-Function Clock incorporates a revolutionary patented water-powered battery -- just top it up with regular tap water and see it spring to life!

That is not all that makes this clock so cool. It also incorporates an ingenious "gravity" sensor – rotate the clock 90 degrees to instantly change from Time to Temperature to Alarm and then to Countdown Timer.

To maintain a constant supply of energy simply refill as the water evaporates, typically every 2-3 months. All the components of the H20 water-powered battery and Multi-Function Clock are recyclable and the benefits over traditional batteries are countless.
