These are couple of lil dudes made out of a conductive clay that was whipped up by one of the most talented YA librarians I know, Mari put on a workshop about simple circuits and as a bonus, we used cookie cutters that were printed on the 3D printer! We also made brushbots from a pager motor, a decapitated toothbrush and a watch battery. I hacked mine to become a “Whopperbot.”
