The main motive power comes from a bucket chain lift (what's the proper name?). The now lofty custard starts its slow liquid journey downwards through a series of water wheels and other such wonders. The wheels provide the power for the next stage - the angled vibrating plate.

As the custard pours onto the plate it is jostled stiff and begins to tumble off the plate down a series of bumpy paths, into chutes where it is accelerated and launched in graceful arcs. It finally makes its way to the model town square, where the now grit sized particled slide into eachother and slowly ooze down the highstreet and into the pool beyond where the viscosity monitor adds water as necessary.
