People enjoy the muddy thrills and spills on a waterslide dug into a hillside in Waimauku on Feb. 23, 2013 in Auckland, New Zealand. Only 2000 people will have the honor of riding the water slides, with one measuring 650 meters long built by New Zealanders Jimi Hunt and Dan Drupstee, of the "Live more Awesome" charity this weekend. The world's longest slide will be open for only two days to  raise funds and awareness of depression.
