Waterfall Swing

Swing through a waterfall

This computerized waterfall with attached swing set gives you the feeling you are about to get soaked by a falling sheet of water, only to have the water part at the last possible moment, allowing you to stay dry. That cycle of suspense and relief, the basis for drama, repeats every 2.3 seconds.

Printing in water

The waterfall is created by an array of thousands of computer-controlled solenoid valves that can be individually actuated to produce patterns and shapes in the falling water.  The video shown here demonstrates the waterfall printing hearts, swirls, letters, and other patterns.
