GREAT PERFORMANCE AND VALUE - Our medium density fog liquid creates amazing atmospheric and smoke effects without drowning out the crowd. This makes our fog liquid a perfect choice for weddings, parties and music events. For thick fog, use our high density formulation which is made for large events such as haunted houses, venues and concerts. | FAST FOGGING FORMULA - Specifically formulated for quick use, our fog liquid rapidly dispenses from your smoke machine to fill rooms and stages without the wait. Long lasting fog liquid provides hours of use and works in all 400W rated foggers. | HIGH PURITY LIQUID - BulkBliss manufactures our fog liquid in-house and guarantees 99.7% purity ingredients! That means no strange odors, machine fouling or skin stickiness! Unlike some value brands, we never use glycerol, which is a cheap ingredient that gums up fog machines. | WATER BASED - BulkBliss fog fluid is a water-based formulation that is 100% safe to use around humans, animals and vegetation. Our facilities are certified by the National Sanitation Foundation, the leading auditor of consumer product safety. | REQUIRES 400W FOG MACHINE - BulkBliss supplies fog for major events and shows. Our fog is designed for a minimum 400W rating spec. Please note that cheaper 400W models on Amazon do not actually perform at a 400W level.
