I also have a problem with him and others calling such things "experiments." They aren't experiments, but demonstrations. We know what is going to happen--well, some of us do, and the rest could just look it up. An experiment implies the answer isn't known or hasn't been confirmed (as in checking another's work for repeatability). But anything you do on the Interwebs that's outrageous and science-y is an "experiment" these days.
