Modern Marvels: Episode 25
Tóm tắt
Join us for another look at big machines. At NASA's Ames Research Center, we visit the world's biggest wind tunnel, part of the National Full-Scale Aerodynamics Complex, and one of the biggest and most complex flight simulators, NASA's Vertical Motion Simulator, or VMS. At the Joy Mining Machinery plant in Franklin, Pennsylvania, giant machine tools form, cut, and measure the enormous individual parts that make up a Continuous Miner, the biggest underground mining machine in the world. But big machines aren't limited to science and commerce. Ride with us on the biggest observation wheel in the world, the London Eye, which stands 443 feet high and provides a 360 degree unobstructed view of London. And we take a look at IMAX technology. The film, cameras, projectors, and theater screens are the largest in the world. Finally, we take a ride on every lawn tender's dream machine--the Claas Cougar, the world's biggest lawnmower.

Skyscrapers are an extraordinary feat of human engineering: exposing millions of pounds of concrete and steel to the enemy forces of wind and gravity. Starting with the foundation and on through the support structures and concrete flooring, every piece of these superstructures has to be super-strong. Go behind the scenes with the five tools that make these buildings possible: the foundation drill rig, the tower crane, the impact wrench, the power trowel, and the total station.

An old-fashioned style of cooking, barbecue has evolved into a modern food craze and spawned a multi-billion dollar industry. We digest famous barbecue cook-offs and visit long-established barbecue restaurants like Arthur Bryant's in Kansas City, where the huge grills and taste thrills of true barbecue are more popular than ever. At home, three out of four US households own a grill. After WWII's end, the phenomenon of backyard barbecuing swept the nation, thanks to inexpensive and mass-produced grills, including the kettle-shaped Weber. Our tour of Weber's modern factories shows how they keep pace with demand by manufacturing more choices than ever, including portable mini-grills. We also examine the variety of fuels available for the savory selection of spicy sauces and rubs. Join us as we devour the mouthwatering flavors of BBQ in this episode.
