Explore the power of microbes with the Kidder MudWatt Classroom Pack STEM Kit 80MW10051. Simply fill the vessels with soil from your backyard (or someone else's backyard), along with anything you find in your refrigerator and watch as within days the attached LED light will start to blink using only the power produced by the electricity-generating microbes in your soil!

The MudWatt is a fun and educational science kit that uses the natural micro-organisms found within the dirt to generate electricity! Within a few days, the MudWatt’s LED light will start to blink using the power generated by bacteria within your dirt. Within a week, you’ll be able to power a digital clock and thermometer - no batteries needed!

Experiment with different types of dirt (and things in your refrigerator) to see which are most powerful through open-ended scientific investigation. Track the growth of your MudWatt's power and bacteria population and unlock new chapters of a comic with the free MudWatt Explorer App (available on iTunes and Google Play)! Dig deep into the science with tons of lesson plans and other educational RESOURCES available for classrooms and science fairs! Enjoy discovery with one of the most creative, interdisciplinary STEM educational toys for the modern world: Microbiology, Energy, Chemistry, Physics, and Environmental Engineering, all in one experience! (MudWatts are reusable and can last for years!)

Note: MudWatts are reusable! They just need to be cleaned between uses.
  • A BIO-ENERGY PET: This Award-winning STEM kit lets you build your own living fuel cell that feeds on soil!
  • FUN: Light up an LED and power a clock using microbe power. The more microbes you grow, the faster the LED blinks!
  • ENGAGING: Experiment by adding stuff from your fridge (like Gatorade) to maximize your MudWatt's power
  • SMART: Track the growth of your microbe population and unlock chapters of "The Electric Microbe" comic book with the free MudWatt Explorer App
  • Use the natural energy generated by bacteria found in soil to power a digital clock and a thermometer
  • All you need to get started is included, save for the soil
  • Includes the equivalent of 10 Core Kits, allowing you to run multiple tests simultaneously
  • Use the app to track the size of your bacterial colony and the power it produces
  • More power unlocks more pages of the comic found in the app
  • An excellent science fair project idea
  • MudWatt Explorer App (available on iTunes and Google Play)
  • No
    MudWatt Anode: The MudWatt Anode is designed to maximize the active surface area to foster a healthy community of microbes. When the Anode is placed within the MudWatt, electricity-generating microbes will develop on its surface.
  • Material: Graphite Fiber Felt
  • Thickness: 0.2” (0.5 cm)
  • Diameter: 3.15” (8 cm)
  • Connection: 9” Titanium Wire
  • Insulation Color: Green

    MudWatt Cathode: The MudWatt Cathode is designed for maximum active surface area for the cathodic reaction to take place. At the Cathode, oxygen and protons interact with the electrons being generated by microbes at the Anode, forming water. This completes the circuit of the MudWatt Microbial Fuel Cell, and allows electrical current to be generated.
  • Material: Graphite Fiber Felt
  • Thickness: 0.4” (1 cm)
  • Diameter: 3.35” (8.5 cm)
  • Connection: 7.5” Titanium Wire
  • Insulation Color: Orange
  • 10 MudWatt CORE KITS
  • 10 MudWatt VESSELS
  • 3 MudWatt Digital Clocks
  • 3 MudWatt MAXTRACKERS (Multimeter and Resistor sets)
  • 18 Alligator Clips (for connecting MudWatts together)
