A fog machine is a device that produces thick vapor, usually from a special fluid heated inside the unit, to create eerie atmosphere for parties, haunted houses and stage shows. Khloé Kardashian used one in her 2026 Halloween display, letting fog roll through skeletons, pumpkins and red-lit foliage for a cinematic effect. It is the kind of theatrical detail that has made her holiday decorations famous far beyond her own front gate.
