The question at hand is whether firewalkers accomplish their spectacular feat (!) by way of an altered state of consciousness or by way of simple thermal physics. You already know the correct answer, but the video puts a dramatic exclamation point on that answer. And Wiseman tells the story well.
The clip as it exists at Google Video is here.
Wiseman warned us that the emcee of the program was also the announcer on an extreme sports show. So his empathy leaves something to be desired. Take out a stopwatch and measure the delay between the word, "commiserations," and his call for "Next!" Upon repeat viewings, notice that Wiseman holds back a smile or two while he describes the setup. I would not have done so well. Imagine multiple takes and me bursting out with laughter every time. It would take a day to shoot.
This clip is a great follow-on to Jearl Walker's Kinetic Karnival episode on The Leidenfrost Effect. I enthusiastically recommend Walker's series for high school physics classes. Note to teachers: you will want to preview the tapes and you might want to hit the mute button once or twice during in-class playback.
The content of Kinetic Karnival is fantastic and highly engaging. But you do have to endure the fact that Walker drinks beer and smokes cigarettes on film. If your students are unaware that adults engage in such behavior, Kinetic Karnival may not be for you.
