Insano water slide in Brazil

If you suffer from even the mildest hint of vertigo, look away now. For the images below are alone enough to send even those who don't have a fear of heights into a spin. The Guinness Book of World Records has officially listed Insano, a 41-metre high water slide in Brazil as the world's tallest of its kind. Equivalent in height to a 14-storey building, the ride plunges swimmers from sky to pool in just four or five seconds travelling at speeds of around 65 miles an hour. [Source]
