I made a wacky interactive widget thingy to illustrate the gas laws. Change the property with the slider and it draws the graph. Just for fun really. A preview may be seen on my web site. Please note: in order to provide a rich interactive experience, my interactive resources are mini-web sites local to your computer. After unzipping, they comprise a folder containing the main .html file and another folder containing the graphic resources and my coding to make the resource work. Double click on the .html file and the resource will work. If, however , you move or delete any of the files from this hierarchy, the resource will not work. stdobbs.com ©D&D production

I made a whacky revision cartoon thingy about the motor effect and fleming’s left hand rule. Just for fun really. (the youtube version has narrative)
