The slide for that certain tingling sensation in your stomach. In the “Robby Robbe” play paradise in Hörstel / North Rhine-Westphalia, you have to conquer a 4.80 metre high climbing hill to experience the unique experience of a self-supporting arch slide with an initial gradient of 60°. A drop of this height usually requires a centre support. However, because this slide was designed as a continuous arch shape and specially welded, it is self-supporting at atlantics.
