I'm going to try to add a video clip. It's of Noam in a thing that we call a "Happy Ball" - at least that's what it was called at this one park we visited. They seem to have this kind of activity at a variety of public parks or nature preserves. In the video it's a pretty small venue but we've also seen a Happy Ball at this big lake - you can ride the ball all around the lake. No life jackets - safety is seen differently here in China where most people never learn how to swim. Yikes! Anyway, Noam wanted me to make sure to tell you that later on in the adventure he learned how to stand up and run like a bear on a log. Hope you also enjoy the sound effects of a typically noisy day in a Xi'an park.
