Fog juice is the liquid that is required in fog machines to create fog. Fog fluids have two primary ingredients – an active one and deionized water. The active ingredient can be propylene glycol, triethylene glycol, glycerin, or a mixture of these. Fog juice is basically distilled water and a glycol, often propylene glycol. Fog machines take fog fluid, heat it till it turns to gas form, and then expel it into the air where it condenses into tiny drops.
To make your own fog juice, you need distilled water, glycerin, and a container. Distilled water is used to avoid mineral buildup in small pipes and tubes, such as in a fog machine. The ratio of glycerin to water determines the thickness of the smoke produced. For very thick smoke, use 30% glycerin and 70% water. For thick smoke, use 20% glycerin and 80% water. For less thick smoke, use 15% glycerin and 85% water.
It is important to use high-quality and safe ingredients when making fog juice. Fog fluids that are pure and clean and made with high-quality and safe ingredients are recommended. Overheating the fog fluid can create unhealthy byproducts, while under-heating it can create fog fluid residue. It is also important to use the exact fluid recommended in the fog machine’s instructions to avoid over- or under-heating.
