MudWatt STEM Kit: Clean Energy from Mud!


Discover the POWER beneath your feet! MudWatt engages kids in STEM in a whole new way, using the power of electricity-generating bacteria living in the soil beneath our feet! Kids experiment with different types of soil (and food from the fridge) to maximize their power output. The MudWatt Explorer App lets kids measure their power, track their MudWatt’s bacteria growth, and unlock an awesome educational comic book! Microbiology, Energy, Chemistry, Physics, and Environmental Engineering, all in one experience!

MudWatt is a bio-energy pet that runs on living microbes and offers long-term fun and learning. Kids maximize their MudWatt's power by experimenting with different soils, different foods from the fridge (like Gatorade), and different temperatures. Along the way, they learn about renewable energy, sustainability, microbiology, electricity, and more.

As your microbes grow, the LED blinks faster and faster! The free MudWatt Explorer App lets kids measure the blinks to discover their MudWatt’s power level and microbe population. Kids track their MudWatt’s growth over the course of two weeks, and unlock a fun and educational comic! (Available for smartphones and tablets). If apps aren't your thing, there is also a calculator spreadsheet for tracking your data manually.

Dig: Any dirt will do! Your soil already has electricity-generating microbes living in it! Try out composts, topsoils, and sediments to see which is most powerful.

Build: Kids construct the MudWatt and learn a ton along the way. Moreover, kids blend creativity with science by designing their own experiments to maximize their power and microbe community.

Analyze + Expand: Beyond the amazing MudWatt Explorer App described above, kids can power a digital clock or connect multiple MudWatts together to try powering other electronics. Kids can also join our online community to share ideas and results with the world!
