A roundabout for performing acrobatic figures such as barrel roll comprises a main arm rotatable around a central axis A and having a longitudinal axis C, a second arm rotatable about an axis of rotation B perpendicular to the longitudinal axis C of the main arm, and a vehicle fixed on the second arm at a distance from the axis of rotation B of the second arm and having a longitudinal axis z directed radially towards the axis of rotation B. The vehicle is fixed to the second arm so that its position with respect to the second arm does not change during the operation of the roundabout.
