Water-Powered Digital Clock

You read that right, it's water-powered!

You will probably have a hard time believing that the water power clock is literally powered by water. But it is true.

Of course science has a big role to play in this. The internal converter simply extracts electrons from water (or other liquid) molecules and provides a steady stream of electrical current acting as a fuel cell to generate power to the clock. In fact, you can use any other electrolytic fluid such as soda, coffee or beer.

So if you're ever tired of having to go to the grocery to buy batteries for your clocks at home, well, tire no more! Give it liquid and you're all set to go.

Go ahead and order your own water (or cola? beer?) powered clock, and help save the world from battery-pollution in  your own little way.
