Swamp Juice by Froggy's Fog was designed specifically for outdoor use as a long-hangtime fog fluid. In optimal conditions, Swamp Juice will stick around for up to 2 hours! While all fog fluids are impacted by environmental factors such as wind, Swamp Juice was designed to make the most of any situation, lingering much longer than other formulas would in the same conditions. Swamp juice is an odorless, non-toxic, water-based fluid made with only the best ingredients available from US suppliers. This means it is incredibly safe for use and will not cause irritation or breathing difficulty for your actors or guests. This also makes it an excellent carrier for our water based scents, which can make your event even more exciting for your guests.
