Rat Race

An inventive scientist rediscovers an experimental apparatus from wartime communications research that causes small animals to pass into an apparently empty space; after brief explosive success eliminating rodents, the effect fades and the device is sold, rebuilt, and offered for commercial use, prompting discussions of practicality and limits when its size and reproducibility prove constrained. The narrative traces practical, humorous attempts to exploit advanced physics for mundane problems, and explores consequences of repurposing military technology in peacetime, emphasizing ingenuity, scarcity-driven improvisation, and the odd gaps between scientific marvel and everyday utility.
