Hydrostatics - balls

Along the lakeside towards Zurichhorn, the parkland is dotted with various interesting objects, more of which anon. We already saw the Tinguely sculpture "Heureka". Close by is this sculpture/fountain/whatever
The ball weighs 1000kg (metric tonne) but is supported effortlessly by water pressure. You can spin it around with two fingers. A nice bit of fun
I love creative water features and fountains.
