Clint,
As I pointed out in my comment on your "Wisconsin Idea" video, your Wonder of Physics shows are the very embodiment of "show me the physics"!
If I had some criticism to make, it would be that sometimes, the demonstrations go too fast and there is not enough "explaining" of what is going on, so that the uninitiated spectator is left mostly with the "magic trick" aspect of the demonstration. For example, the moving spool that can go either way depending on the angle of the string pulling it (at the 6 minute mark) comes out almost like a magic trick instead of as a wonderful application of the concept of torque (as you nicely explain in your own book "Physics Demonstrations: A Sourcebook for Teachers of Physics" when you present this demonstration). Of course, your target audience is quite young and a detailed explanation would go over their heads, but some brief mention of the physics might convey the message that physics is much more than neat tricks! Similarly, a little bit more exposition about the concept of pressure might have made the spectacular bed of nails demonstration (around the 25 minute mark) even more instructive.
Overall, though, congratulations for a dazzling one-hour journey through some of the best demonstrations that physics can offer. I hope your videos do well in this contest. Good luck!
Marc
P.S. If you have a chance to view, comment and vote on my trilogy of videos entitled "This Is Physics" --- where I try to convey the "fun of physics" by focusing on some of the greatest moments of its history --- it would be quite appreciated!
