Necessity is the mother of invention

SAN JOSE, Costa Rica - Tipped off by three plastic pipes mysteriously skimming the ocean’s surface, authorities seized a homemade submarine packed with 3 tons of cocaine off Costa Rica’s Pacific coast.

Four men traveled inside the 50-foot wood and fiberglass craft, breathing through the pipes. The craft sailed along at about 7 mph, just six feet beneath the surface, Security Minister Fernando Berrocal said Sunday.
