This is one pretty cool swing/waterfall. Tell ya the kids these days just have the "coolest" toys and gadgets. A guy named Mike O'Toole created this beauty.
"Water recirculates through 273 independently controlled solenoid valves at the top of the structure to create a wall of water. ... Sensors mounted on the swing set 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."
