An Interesting Idea For A Toy

Last night I dreamed of a toy kitchen for kids that had real running water. It had a reservoir in the bottom (which also served as a weight to anchor the kitchen) and used an Archimedean screw to get the water up through the faucet. The water then drained back down into the reservoir (I'd assume through a filter, if the inventor knows kids at all). In the dream the screw was powered by a hand crank that had to be cranked by a second kid so that the first one could use the running water, but I'd imagine that someone more inventive than I could use "advanced spinning-wheel technology" to make it powered by a foot pedal instead.
