This is an outdoor hanging water wheel decoration. You need a pair of supports for each wheel. Glue two sides onto each wheel so that the "washers" are on the outside. Glue the peg end of one support into the hole end of the other, and chain together as many as you need. The funnel goes at the top of the chain. I used #10 copper wire to attach the wheels and funnel. As long as the wheels are free-spinning, when water enters the funnel it will pour onto the topmost wheel, which will then spin and cascade the water down the chain.
