I was on hackaday
earlier this year and I found an article on squishy circuits. I thought making circuits from play dough sounded like a very interesting idea. I did some research into it and it seemed simple enough; different ingredients created different values of resistance and so on. I thought about it, and decided that I had to make some for myself. I threw some together and it worked great! In this instructable I will provide the recipe for conductive dough, insulating dough, as well as some ideas for circuits you can build out of it. I think this has enormous potential in a classroom setting, being able to teach students how circuits work, something that I didn't even understand until about three years ago. I can just imagine a whole class of students showing off their creations that glow, and make cool noises.
