Antari UVL-01 is a blue UV fluorescent agent for use with snow and bubble fluids. One 100 ml bottle is mixed with up to 5 litres of snow or bubble fluid. The treated fluid produces a fluorescent effect that glows when illuminated by a professional UV blacklight. A UV source is required to achieve the glowing effect. The product is supplied in a 100 ml volume, equivalent to 3.38 US fluid ounces.
