The world's tallest waterslide has been tested by two brave - or foolhardy - men and the pair have lived to tell the tale.

The slide, at the Schlitterbahn waterpark in Kansas, is 51.38m (168ft) tall and is called Verrückt - which means 'insane' in German.

It is 2.38m higher than the previous tallest slide, Kilimanjaro in Barra Do Pirai, Brazil, and taller than Niagara Falls and the Statue of Liberty.

When engineers first tested the drop, the raft fell off the slide, prompting the addition of a safety net as precaution.

Waterpark innovator Jeff Henry, who developed the ride, and ride engineer John Schooley agreed to be the first to trial the thrilling slide.

An earlier video shows the run from a first person perspective, albeit from an unmanned raft.

Verruckt was meant to be operating when the park first opened on May 23, but thrill seekers were left disappointed. It is believed ongoing safety checks are the reason behind the delay.
