H2O 8 Digit Waterpowered Calculator With Replaceable Cell
This fantastic calculator is a marvel of the, erm, water-powered age. To power this aquatic adding machine, simply fill the battery with water, and due to some wonderfully clever science, the calculator generates enough power to last for up to 3 months. When the water evaporates, simply add more, and it starts all over again.
