Boomerang

On this impressive big slide, you'll have to plunge down 16m at the beginning, only to come out just as high on the other side. Like a skier in the halfpipe, you use gravity to swing from side to side as often as possible with a lot of momentum. But at some point, this will also end and you'll have to climb the hill all over again.

Hints:
Size restriction: from 1,20m
Age restriction: -no restriction-
Weight limit:up to 110kg alone 200kg in pairs
