My claim here that placing bubble wrap on a single pane window results in an efficiency gain somewhere between untreated window, and a cheap thermopane seems pretty obvious. What I meant was that the results of my not-too-scientific study were that numbers seemed to post in the center between an entirely different thermopane window, and the untreated single pane window.
This is my visual thinking final project. I wanted to create a solar powered bobble head. unfortunately, i messed up on one step, and that’s adding a second battery and not putting clay over the other magnet. But is easily fixed. Just make sure you put negative and negative side together so that the one can pull and push to turn the magnet on and off. Remember it needs to reject something for the magnet to swing back and forth. Thanks! hope you learned something from my video! lets see what kind of bobble heads you can make!
