In the 80s, I was in a kindergarten where we had a "bird cage" like structure, maybe 2m-3m tall, not sure if it was fixed to the ground. There were a lot of accidents, I barely remember anything about it, beside maybe being painted in blue, but it was fun and scary at the same time. I remember also a few accidents, generally it was mainly kids crashing on different school benchs, ending up bleeding....
