The TED video highlights the importance of hands on learning and how conductive playdough is great way to introduce circuits to little hands as they plug in LED lights, motors or beepers to make their own artful playdough creations. Older kids can even use the conductive playdough to venture into coding. The link to Squishy Circuits has a video on how they work, just click on the "Education" tab on the top right. Get the recipe from the Squishy Circuits link and watch the video for making your own salty conductive play dough and sweet insulating playdough and download the colorful easy to follow directions on how to build many fun and cute projects from a light up rainbow to an airplane with a propeller.
