Tilt-a-Whirls are a flat ride that is aimed at families. It comes in permanent and transportable forms. They are identifiable by their hooded cars which are free to spin on individual poles via small wheels. The 'tilt' of the ride comes from the tilted area often on the back end of the ride that the cars are drawn up, giving them the momentum to spin. The floor rotates at a moderate pace to move the cars up and over the hill.
