Insano water slide, Beach Park, Fortaleza, 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. 
Insano can be found in Fortaleza, Brazil, and for those not distracted by the significant drop below it offers great views of the Atlantic Ocean from the top. The Brazilian beach park website describes the Insano as the most extreme equipment of this type of the planet.
