This is frim the machine room for a water jet system with many nozzles. A computer dirigates the dancing water cascades, which vary from 1 meter high to more than 15 meters. A ver complicated servo system decides when a nozzle operates: direction, time, pressure, nozzle number are components. The spinning sound you hear is from one of many water jet pumps, which idle most of the time, while they suddenly must work at maximum speed. The water jet playing use idling pumping so that pressure can rise momentarily. This is a pygmee water jet player compaared to those in Las Vegas, but the principles are the same.
