In Gleamer’s previous post, “Why does the soap have a spring in it?”, she mentions that I would post some explanation of the soap dispenser. Well I just don’t have enough time to do a detailed explanation so in the mean time you will have to settle for the explanation in the video. I’ve found doing life-sized demostrations of complicated phenomena and mechanisms is a great way to involve the children in learning. It also keeps my mind fit as I try to figure out yet another unintended use for one of their toys or some random piece of junk. (Incidentally, the idea to use the green alligator tube as the spring was Gleamer’s and she shot the video, a true collaborative effort!)
Enjoy the video!
