Half pipe

In Nordic countries, only in Norway you can find a similar kind of slide. Slide alone or with a friend from one side to another, in a chute more than 10 meters high. This is totally mad! The maximum combined weight of sliders on one ring is 140 kg, and there can be max 2 persons / ring. Sliding is allowed in a sitting position, facing forward. The pool depth is 0.40 m.
