water feature

I bought this in Carcassonne when we visited in the late 90s. Drove all the way back (well not from Brive to Calais as we got the train) with this and a lot of French wine straight from the winery in plastic bottles. Even then was thinking ecological! I have tried to have it weather, putting yoghurt on it to encourage moss, but to no avail, Never mind, still looks fine, and makes a welcome noise in the garden.
