I have very fond memories of riding a similar ride to this one in the mid to late 70s when I was much younger. I loved this ride. Of course, it’s nearly, if not completely, impossible to find this ride anymore in the US because, I’m sure, it’s “too dangerous.” There are attractions similar to this at Oktoberfest which is always fun to watch those who’s have a liter or two of beer riding.
For those who’ve never seen or ridden one, essentially, it’s a cylinder. Riders enter and stand against the wall. The ride starts spinning and once it reaches a certain speed, the floor drops away, leaving the riders hanging on the wall. Pure physics.
