Helter Skelter
A helter skelter is an amusement ride with a slide built in a spiral around a high tower. Users climb up inside the tower and slide down the outside, usually on a mat or hessian (burlap) sack. Typically, the ride will be of wooden construction and, in the case of fairground versions, designed to be disassembled to facilitate transportation between sites. The term is primarily used in the United Kingdom. Original public domain image from Flickr
