Test-Riding World's Tallest Water Slide
The opening of the world's tallest water slide has been postponed but a test-ride video shows the thrills of its steep descent.
Verruckt, which means "insane" in German, is a 17-storey, 168ft-tall (51m) water slide - taller than Niagara Falls.
The Kansas attraction sends riders on four-seater rafts plummeting at speeds up to 70mph.
News reports said the two test-riders were designer Jeff Henry and ride engineer John Schooley.
"John and I were the first people down; I'm still recovering mentally," Mr Henry was quoted as saying by USA Today.
"It's like jumping off the Empire State Building. It's the scariest thing I've done."
The ride's initial opening date was moved from May 23 to June 5 to allow for more testing, then pushed back again to June 29.
Then Schlitterbahn Waterpark in Kansas City further delayed the opening, and no new date has been announced.
The park has not given a reason for the latest delay.
Two media sneak preview days were cancelled because of problems with a conveyor system that hauls 100-pound rafts to the top of the slide.
But the company's test ride - with video - aims to prove the slide is safe.
