Clint,
Your Wonder of Physics shows are the very embodiment of "show me the physics", so they truly belong in this contest! The young kids that are your target audience certainly seem to enjoy themselves. In this Wisconsin Idea program, I particularly enjoyed the infrared light/greenhouse effect demonstration around the 12 minute mark: it was intriguing and made an interesting use of infrared detectors and cameras. You are lucky to have so many great demonstration materials and equipment that you can use!
The military guy, the "General of Relativity" (!), was also quite good, although some prospective science students might be disappointed to learn that most physicists do not regularly blow stuff up! The nitrogen cannon was great, and there was a clear explanation of the third law, so there was some "tell me the physics" to go with the "show me the physics". (On the negative side, it is a little unfortunate that some demonstrations do not translate well to video, because of the limitations of the camera, like the shoot-the-monkey demo at the 42 minute mark.)
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!
