ABSTRACT:
A method for displaying the migration of lane oil over bowling alleys during play comprises the steps of incorporating an additive into the lane oil that is non-discernable when viewed with ambient light; applying the lane oil and incorporated additive to the surfaces of a bowling alley in a conventional manner; and selectively illuminating the surfaces with light from a portion of the electromagnetic spectrum having a wavelength to which the additive is responsive, thereby rendering detectable the presence of the lane oil and the migration thereof over the bowling alley.
