Your seat is a simulator and it also has effects that use air and water.
In additon to 3d effects, 4DX equipped auditoriums employ motion enabled chairs, which create strong vibrations and sensations, as well as other environmental controls for simulated weather or other conditions, such as lightning, rain, flashing (strobe) lights, fog and strong scents.
It's a novelty theater experience that involves motor driven seat movement, misters, and other sensory elements. It's like if a movie was a ride at a theme park.
