This is truly amazing. The Amazing Water Clock doesn't use batteries or power from an outlet — it uses a glass of H2O, or any liquid really. Once filled up, the Water Clock's LCD displays the time and date, as its energy converter continues to draw power from electrons in the water molecules. No word on how long one glass of water lasts.
