Office workers and shoppers are having to be careful of any sudden wind change if they are to avoid getting an unexpected soaking.

The giant fountain was set up in the Middle Dock, where visitors can operate it from a power bike to keep the pressure up.

Those with the longest cycle times can win a weekend in Geneva, including flights, water sports on Lake Geneva—and the chance to turn on the real Jet d’Eau!

The original Geneva landmark is visible from the air at 33,000ft, with 132 gallons a second jetted 459ft up by pumps using a megawatt of electricity.

There are 1,849 gallons in the air every second, leaving the nozzle at 124mph.

Unsuspecting visitors to the fountain, which can be reached by a stone jetty from the left bank of Lake Geneva where it pours into the Rhône river, are often surprised to find themselves drenched after a slight change in wind direction.
