Abstract

PHOTOGRAPHIC time exposures of rapidly moving metal droplets which are burning luminously in a gaseous oxidizer often exhibit curious spearpoints. These streak images: (1) become less intense and gradually narrower; (2) suddenly intensify and broaden; (3) finally narrow again as they gradually extinguish altogether. The overall photographic trace resembles a pointed spear, hence the name.
