The concept is 《vertical》.
This work drops about 1000ℓof water from a height of 7 m through a pipe and sprays water only by the water pressure generated there. Water is spraying up to a height of about 3m.
The injected water is sucked up by an electric pump and returned to the tank at the 7m point. In this way water continues to circulate.
Through this circulation, trying to create a "space" where the work is installed.
