New equipment is popping up at playgrounds all over this summer, with more planned for next year. It's all about keeping kids safe, getting them to exercise -- and inspiring their imagination. There's a new, safer version of spinning activities, for example.

Rotating merry-go-rounds, where you stood on a circular platform while someone pushed you by running madly around you, have disappeared. Kids tended to fall off when going really fast. The newer merry-go-rounds have nettings, such as the one in Lindenhurst.
