An amazing technology that involves a compact system of valves, hoses, and pumps, hydraulics have powered the machines that helped build our world. This episode of Modern Marvels examines ancient Rome's extraordinary aquaducts and Universal Studios' theme park - all powered by hydraulics. The work of Blaise Pascal, who uncovered the essential fact that makes modern hydraulics possible, is also discussed.
