The Verrückt (German for insane) is set to become the tallest and fastest waterslide in the world when it officially opens this summer (grand opening is May 23, 2014). Located at the Schlitterbahn Water Park in Kansas City, the waterslide is 17 stories high (good for 170 ft).

Thrill-seeking riders will have to ascend 264 steps to reach the top. However getting down will be much faster as people (in 4-man inflatables) are expected to reach speeds in excess of 65 mph (105 km/h). The current title holder for world’s tallest slide belongs to a Brazilian ride named ‘Insano‘. You can read more about the waterslide in a previous article on TwistedSifter.
