I've always been curious as to how 'real' that wheel and the indoors mechanisms are. Are the wheel and the inside stuff all really directly linked, so they always all run together? And does the wheel actually get turned by the force of the pumped water flow - or is it a Disney cheat and the wheel and/or inside mechanisms run by motor and the water flow is just for show? It all looks very real and convincing... but then the Disney Imagineers have always been very good at making things look convincing.
