Rolling the Sphere

This is in Tomorrow land at Disneyland. They installed this giant stone sphere back in 1998 (I think) when they re-opened Tomorrow land. That was the first time I took my oldest son to Disneyland, I had won passes for the grand re-opening by calling up KLOS and having our pet parrot answer the phone for them. Every time the phone would ring, the bird would say "Hello... Hello, what's up???" Anyway, I've always been fascinated by this sphere. I can't go by it without going over and playing with it for a while. It sits on a stand with pressurized water underneath it, so it is semi-suspended and always moist. You can come up to it and push it in various directions and eventually get it spinning that way. There used to be water jet fountains all around it that would do dancing water patterns, but I guess they probably got tired of people complaining about getting wet and having park visitors trying to spend soggy money or something.
