Water-Powered Robot Bath Thermometer 444487. The robot thermometer uses water-based technology. With its fun design, the thermometer is ideal for the office, home, or anywhere else. Just add water to the "bathtub" and the water battery cells generate electricity.

The thermometer can be placed in the bathtub with magnetic electrical connection points that ensure the energy generated in the "bathtub" powers the thermometer display, which is built into the water robot's head. Fun and educational! Place the robot in the bathtub as shown in the diagram so that the two screws at the end align with those of the bathtub. Add water and watch it measure the room temperature. Change the water? One filling lasts up to 2 weeks.

Package size: 11*11*11 cm.
