Science Fair Project Idea
Do you like playing with squishy play dough or modeling clay? Wouldn't it be cool if you could add lights, sound, or even motion to your play dough creations? In this science project, you will make play dough that conducts electricity, which will allow you to connect lights, motors, and buzzers! This science project is the first in a three-part series on "squishy circuits," which can all be done with the same materials. We recommend doing the science projects in order. Read more

Time Required Average (6-10 days)
Prerequisites None
Material Availability This science project requires a Squishy Circuits Kit and ingredients to make conductive and insulating play dough. See the Materials and Equipment list for details
Cost Low ($20 - $50)
Safety Ask for an adult's help when using the stove to make the conductive play dough. Never connect the battery pack's terminals directly to each other; this is called a short circuit and can make the batteries and wires get very hot. Do not connect the LEDs directly to the battery pack without using play dough; this will burn out the LEDs.
