The Squishy Circuits team developed this activity so that young children (including my own daughters) would have a playful way to explore circuits. Squishy Circuits use two different types of dough as circuit-building materials—one that conducts electricity well, and one that does not. Both doughs are made with readily available ingredients such as flour and salt, and they can be prepared in a pot on the stove. Because of the playful nature of the dough, this activity is suitable for children of all ages.
About Squishy Circuits
The Squishy Circuits project is part of work done by the undergraduate research students in Dr. Thomas’ Playful Learning Lab at the University of St. Thomas School of Engineering. This lab, staffed by undergraduate research assistants, looks at ways in which engineering concepts can be explored through play. In particular, former students Samuel Johnson and Matthew Schmidtbauer were integral to the development of the Squishy Circuits project.
