Meet the Waterfall Swing. A unique and fun swing that does not get you wet. Even though the water falls down, those who go for a ride don’t get too wet. This swing was shown at the 2011 World Maker Faire at the New York Hall of Science. This is how it works:
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.
Pretty special if you ask me though getting a bit wet sometimes is not bad either.
