Seems like magic, powered by science! This amazing clock functions by way of power generated simply by adding water to the unit’s resevoir. The water becomes an electrolyte, allowing the metal probes within to act like a battery. An excellent demonstration of the conversion of chemical energy to electrical energy, as well as a fascinating and unique way to tell time. Keep one on your office desk as a conversation piece, or to tell time anywhere in the home. Makes an excellent gift.
NOTE: clock may not work immediately - give the water time to function properly, and always be sure to refer to the fill lines indicated on the back of the clock
