I've been wondering what the "hanging copper plate" demonstration would look like if you were just seeing eddy currents. I kind of assumed you wouldn't see much movement because otherwise that makes the whole demonstration seem dumb. ...and based on that demo, it really does seem like a dumb way to demonstrate your miracle material. Really doesn't inspire confidence.
