This is a great party centerpiece that everyone can afford. Liquid is pumped from the lighted bottom bowl to the top. Then it cascades back down in a waterfall effect from one tier to the next through holes around the outside of the bowls. You can stack 4 tiers and top it off with a dancing girl (included) or other floater of your choice. Or, you can stack two tiers, attach the clear plastic pipe and top that off with a water faucet (included) or tea pot (included) and the liquid magically appears to be coming from the faucet/tea pot. Holds a little more than 1 gallon of liquid. Interchangeable Water Faucet & Tea Pot fountain tops included!
