There is movement wherever you go in this Constellation. Spouting out from the stabiles are the Musca and Satellite Spinners, challenging children to explore the forces of rotation as they spin around. Linking the two stabiles is the Moon Belt overhead, which flexes and rocks as it is crossed. Even the blue tube rocks back and forth as children climb up it or glide down. In the core of the stabiles the Play Shells provide a place to sit, lay or climb on, to watch the others or have a rest on the way through the Pollux constellation.
