MythBusters (2003)

Answer: A more complex and complete answer probably isn't possible here, since we're dealing with fluid dynamics, pressure, boundary levels, etc. A simply answer would the air in the bed is kept there by the fast moving air coming off the roof of the cab. If there was no "secondary bubble" of air, you would have a vacuum in the bed. When air comes off the roof, it needs a place to touch down, which it is able to do with the top of the tailgate. The fast flowing air moving over the bed keeps the air that's already inside the bed from "escaping." However, the air in the bed is still moving and creates a vortex in the bed, which is described as a bubble. When the tailgate is down, the air coming off the roof will gather at the back of the cab and create drag.

MythBusters (2003)

Star Wars: The Myths Strike Back - S13-E13

Question: When the Myth Busters were testing whether higher ground does give you a huge advantage in sword fighting. Adam and Jamie do the sword fighting themselves, then they ask a sword fighting expert to train them. Why didn't they ask skilled sword fighters to do the fighting instead? It would have been much to easier to determine whether higher ground gives you an advantage by asking experts to do the fighting. Did it actually make sense to ask an expert train them instead of asking experts to do the fighting? If so why?

Answer: Much of the show Adam and Jamie would do various tests themselves to see how much of an advantage something has. The idea being Jamie and Adam are not relying on skill but the advantage they are testing. Even though they do get some training, both their skill levels are essentially at 0. Plus, doing it themselves allows them the chance to talk about the experience. While the experts could have done the tests and discussed the results, some may wonder if the 2 experts were evenly matched to begin with.
