I like movies with special effects about as much as the next guy, but I wonder if these contribute to the problem. The hero on TV and in movies is always defying the laws of physics. It's the cool thing to do -- why shouldn't every 16-year-old give it a whirl?
I know it's not completely new, but if James Bond does it while wearing a tuxedo, or of Burt Reynolds does it why trading wisecracks with Dom DeLuise, I think people can see it as a fantasy. But some of the stuff I see on youtube (kids trying to jump over moving cars, for instance) makes me think that kids no longer see a line between fantasy physics and reality physics.
