Circuit Clay - The Easiest Way to Learn About Electricity
The Circuit Clay activity book will teach you about circuits and electricity, all with the use of clay, LEDs and a battery pack. With four different colors of conductive clay, and a fifth of insulating clay, you'll be able to create your own clay structures and then watch them light up as you insert LEDs and the battery pack wires into the appropriate clay. Start with some easy projects, learning about basic circuits and how to properly use the insulating clay, and then progress to some of the more difficult models before designing your own!

While they have definitely outgrown that office, their galactic headquarters is still staffed entirely by human beings. At least, it is for now.
