That's an interesting experience. I'd say that the idea people have about water in pipes is probably overly simplistic as well, and an analogy to an equally poorly understand concept can't help very much. To pick up your example about electron speed vs. signal speed: Water pressure is transmitted at the speed of sound, which is much, much higher than the speed of water flow -- water taps wouldn't work otherwise.
