Use homemade conductive and resistant play-doh to build electronic sculptures that light up, move, and make sounds. Anyone who has ever tasted play-doh knows that it’s a salty substance. The salt allows electricity to flow through the dough. With the addition of a homemade dough that substitutes sugar for salt, the dough becomes resistive instead, and complex circuits can be created to power all kinds of objects. We use battery packs, LED lights, hobby motors, and buzzers to explore electricity in a fun, hands-on way.
We were inspired by this TED talk by AnnMarie Thomas to develop this activity.

We are passionate about sharing our work and developing a community of people interested in these activities, practices, and ideas. The guides below are free to download and use to help you get started with tinkering, whether it's at home, or in your school or educational institution.
