Hypnotic is code-name for the Vortex machine at Fun Stop.

Vortex is a machine that creates an illusion of you being suspended in air, while you make an attempt to walk across a bridge within the machine. The bridge is placed in the center of the barrel. The barrel has hypnotic markings all over it, and these markings revolve around you as you stand on the bridge ready to walk across, while the barrel rotates. The revolving of the barrel and the markings around you creates an illusion in you, that the bridge you are walking on is also about to revolve along with the barrel, forcing you to cling on the ladder for dear life.

Though the length of the ladder is but a short walk, most of the participants remain clinging on to the ladder barely attempting to walk because of the illusion of falling.
