Sweet Lincoln's mullet, have a look at this. Insano, in Fortaleza, Brazil is the world's tallest waterslide at 41 meters. Ride this and you'll be travelling at over 100km per hour.
"You are about to live through one of the most extreme experiences of your life." says the official website.
"The Insano is the highest water slide in the world at 41 meters high, a record listed in the Guinness Book of Records. Its height is equivalent to that of a 14-storey building.
"As a consequence of its height and slope, this water slide provides an extremely rapid descent - taking between four and five seconds - at a speed of 105 km/h. Because of these characteristics, the Insano is considered the most extreme of this type of equipment on the planet. At the end of the track, the Insano provides you with a relaxing dive into the swimming pool."
Brilliantly they then list in the warnings: "There is only one position for going down this equipment."
