I originally found the idea for squishy circuits in the book Design Make Play. Squishy circuits are constructed from two different playdoh recipes. One which allows electricity to flow through it (conductor) and one which does not (an insulator). Recipes for both types can be found here
My itty bitty maker helped me make the dough. She likes to spoon out ingredients and stir them up. And then she got to knead the dough. I colored the conducting dough green (go!) and the insulating dough red (stop!). We then connected a battery to the dough and started putting in our LEDs. LEDs are directional. This means that they only allow current to flow in one direction, so if it doesn't light up right away, try turning the LED around.
