(PHOTO NEWS) — People enjoy riding a 350-meter-long water slide on a street in Seoul’s Seodamun Ward on July 19, 2015. The ward office operated the water slide, the longest one in South Korea, in a festival aimed at helping people cool down in the summer heat. No, it is NOT the longest water slide in the world. The world’s longest water slide was a temporary installation in Waimauku, New Zealand, in February 2013 — constructed with a length of 650 m, of which 550 m functioned properly, according to Wikipedia.
