Sydney has quite a lot of water features, if you go looking for them, but these ones at Darling Harbour will keep you amused with their cool interactivity! Turn this wheel around, and watch it scoop the water up, and then see it flow through the middle into the drains on either side, and down the funnel. There’s also a corkscrew thingy, little dams, gates, pumps and other neat stuff for kids (and us big kids) to play with. This is a really nifty place to visit for a few minutes. It’s located not far from where Sega World used to be. There are also some cool fountains in the region too.
This is called a noria.
