Calculator powered by water

Batteries will never be needed again, especially for applications like making simple calculations, all that is needed here just to power this up is a little water poured into the back of the device.

This is an amazingly neat little device which gives everyone an idea of what is possible by using a bit of technology and lot of eco friendliness. This water powered calculator is quite safe, has a fair sized screen and basic functions.

Priced at $8.99
