H2OTM introduces The "Waterboy" Thermometer using H2OTM water power technology. This fun design thermometer is a real eye catcher on your desk at the office, at home or anywhere else. Simply add water into the "bath tub" and the H2OTM water battery cells generates electricity. The waterboy thermometer can be attached to the bathtub with magnetic electrical connection points, which ensure the energy, generated in the "bath tub" powers the thermometer display, which is integrated in the head of the waterboy. Fun and educational!
