We wrote up a fun little project where you make a light-up caterpillar using conductive dough, a 9V battery, and LEDs. It’s simple enough for kids to build (and safe with supervision), but still highlights core electronics concepts like polarity, circuits, and conductivity.

The post includes step-by-step instructions, photos, and some notes on why the dough works as a conductor. We think it's a fun way to introduce kids to electronics or just to play around with a squishy medium for prototyping.
