At the end of last week Rod had promised everyone he would make a pickle glow the following week. Everyone was excited to see if this wonderment would actually take place. Well, he didn't disappoint. Amazingly, Rod managed not to shock himself, one pickle was so exciting that we all rallied him to try three. We were running back and forth to turn off the lights and take pictures in a flurry of pickle burning delight. It was so fun to see the pickles glowing like crazy, as well as smoking and stinking up the room for the rest of the day. He did give a very scientific explanation of the phenomenon, complete with illustrations, but I am not going to do a fine job of repeating it here, maybe he will chime in at a later date.
Following up on the paper circuits we decided to delve into squishy circuits. I found recipes on line from University of St. Thomas for conductive and insulating dough that I could make so we could build three dimensional conductive work, using little AA battery packs and LEDs.
For some reasons, no matter how many times I tried, I could not make insulating dough, but the conductive dough was working well. I ended up just assembling a melange of insulating materials from around the house - legos, cork, balsa wood, etc - to take in to use for insulating. I can't fathom why everyone else on line seemed to have no trouble with the formulation of both doughs and I endlessly struggled, but the kids seemed to have fun regardless.
