12:00 PM Modern Marvels. Snackfood Tech. Extruders, molds, in-line conveyor belts. Are these machines manufacturing adhesives, plastics, or parts for your car? No, they're making treats for your mouth--and you will see them doing their seductively tasty work in this scrumptious episode. First, we visit Utz Quality Foods in Hanover, Pennsylvania, that produces more than one million pounds of chips per week, and Snyder's of Hanover, the leading US pretzel manufacturer. Next, we focus on the world's largest candy manufacturer, Masterfoods USA, which makes Milky Way, Snickers, Mars, and M&Ms;, and take a lick at the world's largest lollipop producer, Tootsie Roll Industries. And at Flower Foods' Crossville, Tennessee plant, an army of cupcakes rolls down a conveyer belt. The final stop is Dreyer's Bakersfield, California plant, where 20,000 ice cream bars and 9,600 drumsticks roll off the line in an hour. CC [TVPG]

01:00 PM Modern Marvels. Brewing. It's one of the world's oldest and most beloved beverages--revered by Pharaohs and brewed by America's Founding Fathers. Today, brewing the bitter elixir is a multi-billion-dollar global industry. Join us for an invigorating look at brewing's history from prehistoric times to today's cutting-edge craft breweries, focusing on its gradually evolving technologies and breakthroughs. We'll find the earliest known traces of brewing, which sprang up independently in such far-flung places as ancient Sumeria, China, and Finland; examine the surprising importance that beer held in the daily and ceremonial life of ancient Egypt; and at Delaware's Dogfish Head Craft Brewery, an adventurous anthropologist and a cutting-edge brewer show us the beer they've concocted based on 2,700-year-old DNA found in drinking vessels from the funerary of the legendary King Midas.

Find out how horsepower was first coined as a marketing tool for the steam engine in the early 1800s and meet the horsepower police--the Society of Automotive Engineers who test today's most powerful car engines. Feel the amazing power of Unlimited Hydroplane racing as 3-ton boat-beasts careen across water at speeds of over 200 miles per hour. Journey to the bowels of an enormous container ship where the world's most powerful diesel engine provides over 100,000 horsepower. At the Hoover Dam, watch as it harnesses the enormous power of water. Explore the 80,000 horsepower pumping units at the Edmonston Pumping Plant that delivers 2-billion gallons of water a day to thirsty Californians. And sit behind the steering wheel of a new generation of hybrid cars that boast 400-horsepower yet get 42 miles per gallon of gas. CC [TVPG]

03:00 PM Modern Marvels. Nature’s Engineers. Towering skyscrapers buzzing with life, intricate tunnels connecting entire communities, mighty dams that tame the wildest rivers--this is construction animal style! Take a walk on the wild side as we investigate common creatures seemingly designed to alter their habitat and remake the world. Our ability to learn and capacity for abstract thought may separate us from beavers, honeybees, birds, termites, and spiders, but these engineers of nature remind us that we're merely the latest in a long line.

04:00 PM Modern Marvels. Extreme Aircraft. Join us for a supersonic look at some of the most cutting-edge aircraft ever developed--from the X-1 that first broke the sound barrier to the X-43 Scramjet that recently flew at Mach 7. These extreme aircraft have made their mark on aeronautical history, and sometimes on political history as well. The U-2 and SR-71 spy planes played a crucial role in the Cold War, and now Lockheed Martin's top-secret "Skunkworks" division is touting the new "air dominance" fighter plane-- the F/A-22 Raptor.

05:00 PM Modern Marvels. World’s Biggest Machines 3. Giant robots on the factory floor and in outer space.

These giants must be seen to be believed! In this episode, we travel over land and sea to find these and more of the biggest, baddest, most audacious feats of engineering in the world.. CC [TVPG]

06:00 PM Modern Marvels. 80’s Tech. Remember "brick" cell phones, Pac-Man, Rubik's Cube, Sony Walkman, and the first music CDs? Remember all the new and exciting gadgets of the 1980s? Join us as we investigate the transition from Industrial to Information Age--a digital decade dedicated to ergonomics and entertainment. The microchip ushered in an era that revolutionized the way we work, play, and communicate. And we tour Silicon Valley--birthplace of some of the greatest inventions from an amazing time of change, including the modern personal computer. Steve "Woz" Wozniak tells us about the evolution of Apple computers, and we talk to Sony--makers of the Walkman, Betamax, and the first CD players. A visit to the Computer History Museum shows fun technological "artifacts", primitive by today's standards. At Intel, makers of the first microchips, we learn why technology moves at such a fast pace. We also take a ride in a DeLorean DMC-12 sports car--few things moved faster. CC [TVPG]

07:00 PM Modern Marvels. Freight Trains. They are the life blood of the American Economy, transporting 1.8 billion tons of freight each year, carrying everything from crops, to consumer electronics, cars to chemicals, not to mention coal and just about any other item that you can think of. This program will take you to what is considered the greatest freight transportation system in the world, the Union Pacific's Bailey yard--a pit stop for much of the nation's freight on its journey across the continent. We'll also explore the history of freight transportation from its humble beginnings as tramways in mines to complex system of rails that stretches to every corner of the nation. CC [TVPG]
