Essential Info:

• The work (an installation of three urchins) requires one 10 amp power point for all fans and lights 

• The work uses water as internal ballast - so a hose and good water pressure is essential (450 litres for the whole work)

• The work must be staged on a surface that is reasonably flat, ie not a sloped hillside, but can be grass, cement, gravel etc.
