Just add a teaspoon (5 ml) of our Glow-Bright Concentrate to a liter of any water soluble liquid and it will glow a bright yellow/green under ultraviolet light. Add to our slime mix for glowing slime, or use in the water for our Growing Spheres for a glowing marble effect. Perfect for creating glowing potions for Halloween. The 2 ounce (60 ml) bottle will make over 2 gallons of glowing liquid. Caution: Product may stain some surfaces.

Note: This is not a standard white-light activated Glow-In-The-Dark product. An ultra-violet "blacklight" is required for the glowing effect.
