Explore the power of microbes with the MudWatt Grow a Living Fuel Cell. Simply fill this kit with soil from the backyard and follow the instructions. Within days the attached LED light will start to blink using the power produced by the electricity-generating microbes in the soil! Track the growth of your MudWatt's power and bacteria population and unlock new chapters of a comic with the free MudWatt Explorer App! The MudWatt makes a perfect educational kit for classrooms and hobbyists since it incorporates a wide range of scientific topics. It's easy to incorporate the MudWatt into a class discussion on microbiology, soil chemistry, electrochemistry, or electrical engineering. Microbial Fuel Cells (MFC) are bio-electrical devices that harness the natural metabolisms of microbes to produce electrical power. Within the MFC, microbes munch up the sugars and other nutrients in their surrounding environment and release a portion of the energy contained within that food in the form of electricity! A fun and educational kit for any age!
