I still remember going to this park as a kid, I'm talking young, just before it closed. There were these electrically powered counter-rotating foam cylinders, large diameter, rotating into each other. You were supposed to bop your friends with foam covered nunchuks while maintaining balance.

As a little kid, I was able to easily identify the danger of falling into the middle and getting pressed down into the very shallow ballpit below. Anyone more than 4ft tall would probably get hurt.

And this little monstrosity, like 10ft in length plus a little ball pit around it, was just chilling in the middle of the path, like there was nothing out of the ordinary. Sun beaming down on it and all. Just wow.
