- The ultimate celebration and investigation of engineering excellence.
Celebrating ingenuity, invention and imagination brought to life on a grand scale, MODERN MARVELS® tells the fascinating stories of the doers, dreamers and sometime-schemers who created everyday items, technological breakthroughs and man-made wonders.
It seems so simple, just a little change in air pressure, yet its applications are nearly limitless. In this sweeping MODERN MARVELS® episode, see how vacuums improve our lives in countless important ways beyond cleaning floors. Learn how giant vacuums clean up after disasters like Hurricane Katrina and underwater vacuums save coral reefs by suctioning up invasive algae.
Discover how mail was delivered in the 19th century with intricate networks of pneumatic vacuum tubes. Visit the Hoover Vacuum Museum to how the household sweeper was invented and learn about some unusual applications. And take an out-of-this-world trip to the planet's largest vacuum chamber at NASA's Plum Brook Research Center where vehicles and gear face the "big empty" before their journey into the final frontier.
No pressure, but you're going to love this look at VACUUMS.
