World's Longest Water Slide Built By New Zealand Charity (VIDEO)

A New Zealand charity working to combat depression is building the world's longest water slide -- 650 meters of narrow white water -- on a private ranch land outside Auckland. Live More Awesome, the group behind the project, plans to open the temporary slide, along with two more slides nearby, for two days starting February 23.

LMA raised funding for their wacky project through the crowd funding site Indiegogo, where they offered supporters a variety of incentives, including tickets and the opportunity to enter a rubber ducky in a race down the flume. With 37 days left for supporters to offer the group money, LMA has received a little over $20,000 of its stated $70,000 goal.

When it debuts, the New Zealand water slide will be surpassing the Mammoth at Indiana's Splashin' Safari, a ride that -- rather surprisingly -- offers fewer chances for close encounters of the bovine kind.

Jimi Hunt, one of the brains behind this Kiwi answer to the Insano, claims he already built the world's biggest slip 'n slide. So he's qualified at least.
