Setting up the Experiment

We have wanted to make electric play dough as long as we can remember. I think it was over a year ago when we saw this awesome experiment with squishy circuits and recipes for conducting and insulating dough.

Electric Dough Ingredients

For this experiment, we only created the conducting dough and we adapted the recipe just a tad by adding lemon instead of cream of tarter. For the full recipe be sure to check out the original recipe here.

What is Electric Play Dough?

Electric Play dough was originally designed by St. Thomas University and is known as “squishy circuits”. The basic premise is that the play dough acts as both an insulator and a conductor of electricity in order to form shapes and add with lights, sirens, and motors.

Electric Play Dough is a great way to teach basic circuits to children. You can teach a simple circuit or build on that knowledge to include parallel and series circuits, electrical load, and even squishy sound music! The possibilities are endless.

Here is one of the creators of Squishy circuits sharing more about the research, recipes and hands-on learning.


This video is great for showing you more about how to make electric play dough. We went a slightly different route. I  love this hands on science lesson with real kids, to show you just what it might look like in your home or in school.

For us, this was the beginning of our exploration on Squishy Circuits. What happened during our lesson was slightly different.

We had our dough made. Just one… the conducting dough because that Legoman (age 9) had an idea and was stuck. He really has to try things first hand to see if they work before changing his thinking and trying a new way. So, I ran with it. He wanted to use our Snap Circuits to make a circuit. They are one of his favorite toys and he was certain that the dough would work to create a new circuit.

First, he loaded up the battery pack and attached the wires. He checked that the circuits worked from the snap circuits kit and then replaced the snap with electric play dough. It WORKED! Now he wanted to cover the light with dough completely leaving only the LED showing. This is where trouble happened.

If you have watched the other videos I included you might know why this method didn’t work. I could have told him why it didn’t work, but instead we were problem solving. The solution he ended up with was not at all what I was expecting.

Remembering his potato Clock from Christmas, he decided to gather the materials and try to replace the potato with electric play dough. However, he didn’t just want a glob of dough… No! He wanted it to resemble his favorite thing on the planet.. Lego!

Materials for Lego Electric Dough Clock

Did I really just write “Lego Electric Dough Clock”? Is that even a thing? Apparently, it is now! See, not what I ever would have planned on my own!

Bottle Cap {to form the top of the head}

Googly Eyes

Marker {for the mouth}

To make a Lego Head out of Play dough, simply make a large clump of dough and roll it into a ball. Once you have it in a nice ball, roll it on the table until it is the height of a cylinder you prefer. At this point, you can pinch a small second on the top and shape it with the bottle cap.

Add your googly eyes and draw on a mouth and you are ready to go!

Now, its time to connect your potato clock materials. Following the instructions in the kit, you can create your circuits that run to and from the clock.

Since the circuit needs to run in one direction, you might have to experiment with which side to place your wires. Your Lego Head should now complete the circuit so you can tell time!

My son was pretty pleased with himself. Tomorrow…. adding the insulating dough and experimenting some more! We have some monsters we want to make and test! My son also has a helicopter he thinks he can build with electric dough. What do you think ?

We had a lot of fun putting together this little video while we were making and experimenting with our electric play dough! Have you ever made electric play dough? What did you do with it? I would love to know and see!
