Black Light or Ultra Violet is generally used at all-out festivals. Sometimes a number of high-intensity sources are placed around the auditorium. Fluorescent spray cans of colored points, UV pigments, and UV excited chalks in assorted colors are passed around. Symbols are painted on foreheads, hands, clothing, etc. These are invisible until excited by the black lights. Sometimes large war-surplus weather balloons are sprayed with UV phosphors and inflated and bounced around as toys. Usually the band and dancers have special UV fabrics in their attire.
