The Rotor amusement ride was designed and patented by German engineer Ernst Hoffmeister in 1948.

The ride still appears in select amusement parks in Europe, although travelling variants have been surpassed by the Gravitron.

The rotation of the barrel creates an inward acting centripetal force supplied by the wall's support's force, equivalent to almost 3 g. Once the barrel has attained full speed, the floor is retracted, leaving the riders stuck to the wall of the drum.

In the United States, two main companies were responsible for production; the Velare Brothers and the Anglo Rotor Corporation.

The yellow lines on the barrel wall indicate the level the floor is at during different points of the ride; the higher line is level with the floor when the ride begins.
