A Fun, Environmentally-Friendly Green Product! A Working Clock that Runs on Water!
This amazing amalgam of science and engineering uses no batteries, no solar cells, no electricity! Instead it is powered by water, fruit juice, soft drinks, coffee, or just about any electrolytic fluid.
To run, simply select the “fuel” of your choice and use it to fill the clock's “fuel cells”. Set the time and date and off you go! Experiment with different fluids to see which works the best and/or the longest.
Features a cool translucent “iMac” style body with silvery chrome face and huge digital display. Applies concepts of over-potential and charge transfer across interfaces - or just use it to tell time. Very, very cool.
