...defense mechanism as sophisticated as tomorrow's anti-missile missile. Attacked by a water strider, a fast, long-legged bug that is its customary nemesis, the Stenodus simply squirts out a charge of fluid detergent from a pair of abdominal glands. The detergent destroys the thin elastic layer of water that marks the boundary between fluid and air. With that surface tension gone, a small water wave rises and propels the Stenodus out of danger. When the attacking water strider, which is normally supported by the film of surface tension, tries to follow, it sinks and drowns...

Since 80% of North American's business depends on the new technology of missiles, electronics, rocket engines and atomics, the company considers the money-$4,500,000 last year-extremely well spent...
...things are obvious to the expert but hasty eye. The moon's "seas" do not seem to be covered with deep, fluffy dust, as many lunar experts have argued.
