The Swing Chairs, which is a carousel with swings on long chains, in which, the riders are supposed to feel the impact of the centripetal force on their bodies. Riders can bring a cup of water to study the surface of the water. As the carousel rotates, the swings hang out from the vertical, thereby enabling the chains to provide the force giving the required centripetal acceleration, while still counteracting the force of gravity. During the rotation of the tower, riders can observe the direction in which the water tilts. The aim of the experiment is to understand how it is possible to detect rotation.
