Coanda in a private garden

An example of the Coanda effect in a private garden in south London. The water is allowed to spill over the edge of a bowl and adheres to its underside, converging towards the central trunk. The piece is 1.9 metres high and fabricated from cast, spun and rolled mirror-polished stainless steel.

I first noted this phenomenon occurring on one of the two fountains in front of St Peter’s in Rome, which was not perfectly level, so that water was spilling off one side. I could not resist the challenge to make a perfectly level and overflowing vessel that would enable me to achieve total coverage and adherence of the water from the top of the sculpture throughout its descent.
