MudWatt STEM Kit - Grow Your Own Living Fuel Cell
Electricity from mud. That's the game, or rather, the challenge your kiddos will get from a MudWatt STEM Kit. The kit comes with all the groundwork for building a living fuel cell, and all you'll need to add to start cultivating your electricity-generating microbes is, well, some ground.
The MudWatt invites kids to experiment with different types of soil, plus food from the fridge, to nurture the natural microbes living in them. As the bio-pet begins to thrive, the MudWatt app allows mad little scientists to measure their power, track the microbes' growth, and power a digital clock and other electronics.
