Such an awesome installation!
The Waterfall Swing is a collaborative project between Mike O’Toole, Andrew Ratcliff, Ian Charnas and Andrew Witte.
Towering steel swing set holding arrays of mechanical solenoids that create a water plane falling in the path of its riders. Formed from a tangent of ideas raised from the study of interactions of water as space, the swing is the first in a series that play with interaction in rides and installations. Riders pass through openings in a waterfall created by precisely monitoring their path via axel-housed encoders, creating the thrill of narrowly escaping obstacles.
How the Waterfall Swing works:
Water recirculates through 273 independently controlled solenoid valves at the top of the structure to create a wall of water. This water starts from a collection pool on the ground and is pumped up to a large pipe that feeds the solenoids. Sensors mounted on the swingset gather information about the angle and speed of each swing. That information is sent to a computer that predicts the action of the rider. The computer then creates a hole in the wall of water, allowing the rider to swing through without getting wet.
