When no one wanted to build the world's tallest and fastest water slide, Jeff Henry built it himself. 

So when Verrückt was completed, and it was time to test the 168-foot coaster in his Kansas City, Kansas, water park, the choice of test riders was rather easy. 

The guinea pigs: Henry, owner of Schlitterbahn Waterparks and Resorts; Henry's assistant; and head designer John Schooley. 

"It was terrifying," Schooley said. "It was great fun, but it was actually terrifying." 

The slide finally opened to the public on Thursday, July 10, after several weeks of delays. Technical glitches forced the original May 23 opening date to be pushed back three times, a park spokesperson said. 

Officially certified by Guinness World Records in May, Verrückt -- which is German for "insane" -- is 5 feet taller than the previous record holder, a water slide at a Rio de Janeiro country club. 

Verrückt is precisely 168 feet 7 inches tall. To put that free fall in perspective, it's longer than a plunge at Niagara Falls. 

Schooley stressed, however, that the ride is more than a single drop, calling it an "extreme thrill" without comparison. 

"You have three or four experiences on the ride," he said. "There is a 3-second free fall before you get launched into a weightless situation for a few seconds, and then you come down like a roller coaster and have a long splash down." 

The origins of Verrückt are as extreme as the ride itself. 

According to Schooley, owner Henry was at a trade show and simply decided he wanted to build the tallest, fastest water slide at one of his five Schlitterbahn water parks. He immediately shopped the idea to vendors, who declined, but he refused to be denied. 
So, is it just one big fall?
"You have three or four experiences on the ride," he said. "There is a 3-second free fall before you get launched into a weightless situation for a few seconds, and then you come down like a roller coaster and have a long splash down."
