This quirky looking eco-friendly calculator is powered by free energy. Simply fill the three water-powered batteries to the brim and plug them in to the face of your calculator!
Water-powered batteries consist of two electrodes that are made out of special alloy. When you immerse the electrodes in water they produce electricity through an amazing chemical reaction!
Just refill the batteries as the water evaporates from the cell (typically every 2 or 3 months). It's easy to tell when you need to top up since the batteries are clear like the calculator. Very cool!
With eccentric green buttons and similar battery plugs, this calculator is a fascinating feature for your desk. The batteries will last for a minimum continuous life span of two years!
Recommended for ages 10 and up.
