When the amnesiac Data began investigating the mysterious illness that was affecting the Barkonians that he befriended in 2370, he coated a piece of cloth with the liquid used in lamps, which he demonstrated would become luminescent when exposed to an energy source. With it, he was able to determine that a metallic pendant they had appeared to be an energy source. When Talur inquired where the pattern of light causing the luminescence was coming from, Data explained that he believed that a stream of particles was emanating from the pendant and hitting the cloth.
