Re: Teach Kids Electronics Using Dough: Light Up Caterpillar Project
#2We 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.

#3Someone gave one of my kids a dough-based circuit activity once. I recall it was hard to prevent the various globs of dough from touching and we burnt out most of our components within a few minutes. The experience was very poor compared to something like snap circuits, or even just using a bread board.
If the LEDs and whatnot were in modules with polarity protection there might have been something there, but I'm not convinced the dough adds much over just a bag of random components for teaching kids about circuits.

#5Corrosive salt dough is very much not "the perfect material for a circuit". When you put two wires into salt dough, it becomes a battery; when you pass current through it, that destroys one of the wires.
