The Amazing Water Clock: a glass for you, a glass for Father Time

The Amazing Water Clock doesn't want your batteries or power from an outlet — it's asking for a glass of good ol' aqua, or any liquid really. Once filled up, the Water Clock's LCD display will show you the time and date, as its energy converter continues to draw power from electrons in the water molecules.

It's a no frills clock for $13, and you're really just paying for the novelty of an alternate power source. If you love the idea so much that you want them all over your house, you can buy them in pairs for a discount at $20.
