There is a men's urinal at the Champagne Creek rest area in the Cromwell Gorge with a rather energetic water flow which if you are close will wet you.
As a regular user some years back I added "Pull and Step Back" under the chain. Subsequently somebody has removed the last three words ... one day I may remember to have a felt tip with me to replace the words on the breeze blocks becuase the water still flows energetically Sorry no photo.
