Remember the fascinating Rain Room installation in London? The Dash7 Design studio created a similar interactive installation, presenting a swing set with water pouring down… but never actually touching you! The Waterfall Swing is a brainchild of Mike O’Toole, Andrew Ratcliff, Ian Charnas, and Andrew Witte and was first presented in the World Maker Faire in 2011.
The essence of the trick are the 273 solenoids valves on the top bar of the swing. Not only do they pour the water, but their computerized mechanisms keep track of the speed and the movement of the swing, in order to stop the water just when the people are going right under the bar. That way the wall of water forms a gap for the swing to go through. The thrill of getting caught in the rain must keep the adrenaline high!
