An amusement ride involving rotations around three axes offers a large-scale illustration for the study of dynamics in three dimensions. The forces on the rider can be measured with co-moving accelerometers. As a first approximation, the different motions can be treated separately, but the combination of rotations is found to lead to a relatively large Coriolis effect. A mathematical description of the motion automatically combines all the different effects and offers a useful programming exercise.
