We've heard a lot about the world's tallest water slide—but now you can watch exactly what it's like to ride the thing as a member of the public.

The Verrückt—which means "insane" in German—stands 168 feet and 7 inches tall. It's so big that even its designer admitted to being terrified of riding the slide. And holy shit, he wasn't wrong.

In the video, the guys on the slide hurtle down the chute, reaching 43 mph and their heart rate soaring to over 120 bpm. Just watching it, yours will rise a little too. [YouTube]
