Not to derail the thread, but the idea that airplanes fly by the Bernoulli effect is actually something of a minor peeve for me - yes, it can produce a minor amount of lift (if you don't have a symmetrical airfoil, like any military or aerobatic aircraft) but mostly those shapes are abou avoiding drag - an airplane flys because the shape of the wing, angle it's traveling at relative to the air, or both, make it push the air down from the bottom and behind it, and good old Equal & Opposite Reaction pushes the airplane up in return. How else could a paper airplane, or one of those dollar-store balsa wood rubber band powered kits fly? For Arthur, I'd tell him to stick his hand out flat to one side while riding a broomstick, and play with cupping his fingers to see how the air pushes it up and down. IRL, you can do the same thing from a car window at 35-40 mph - doing this is how I learned to visualise the way my RC airplane would react. There was an essay I wrote for an English Composition class on the topic titled "Learning to Fly" that I really regret losing with one of the computer failures six or eight years back.
