This document introduces circuits that can be built using conductive play dough and includes instructions for making the play dough. It describes two experiments involving building a basic circuit with an LED and constructing a simple switch. It also provides credits and links to related resources for learning more about squishy circuits.

6. Conductive Play Dough
Mix:
¼ cup water
½ tablespoon vegetable oil
food coloring
Stir that into:
1 cup flour
½ cup salt
Mix it, then knead it with extra flour until it is the consistency of fun.
