These kids look so thrilled every time they make something that lights up. This is definitely something I need to do, given that I’m just a big kid myself. I’ve got lots of little tweeters, LEDs, motors, battery packs, et cetera. And homemade play-doh is easy enough to make, and I suspect I could even make it with different resistances. Oh, ideas are germinating already!
