Chinese "Hacky Sack" at the Temple of Heaven

We call these things Chinese hacky sacks... not sure what they are really called, but they are used much the same way as a hacky sack. They are a small bundle of colored feathes standing upright in a stack of metal rings, with a flexible plastic base. The rings sort of clink together when the toy is kicked and when it lands. We first discovered them on our adoption trip and brought a couple home for the kids to try. They were being sold in the Temple of Heaven park last week very inexpensively, like two for 5 RMB, which is about 65 cents. The kids bought them and had fun with them throughout the day. Here they are playing at the Circular Alter area. Somehow it didn't seem irreverent since they were a Chinese toy, and sold inside the temple park. Our guide, John, couldn't resist putting on a little show for the kids, demonstrating his superior skill with this little bunch of feathers and rings!
