How do I make one of those low voltage RubberDuck-Person1-Person2-RubberDuck circuits. The people hold hands and the rubber duck lights up. I've googled it but I'm not finding it. Maybe I don't know what to search on.
It doesn't have to be a rubber duck, but I saw that today at the Boston Museum of Science
