Modern Marvels is going big, and counting down. We take the "best of" Modern Marvels and give you the MEGA Top 10 countdown. On this edition: Speed. It's a pure adrenaline rush as we race the top 10 fastest marvels we've featured down to the speediest of all.

Perhaps no field has experienced the revolution in velocity more acutely than transportation. We look at five blazingly fast technological marvels that have pushed the speed limits to the very edge, each with its own unique and dramatic history: the world's fastest production car (Sweden's Koenigsegg CCR); the world's fastest train (the Maglev in Shanghai); the world's fastest boat (The Spirit of Australia); the world's fastest roller coaster (the Kingda Ka) and the fastest thing on earth (the Holloman High Speed Test Track), used to test highly sensitive equipment for many branches of the government and commercial clients.

It's full steam ahead when we drop in at Jay Leno's garage as Jay fires up two of his classic steam cars and takes viewers for a couple of rides. Jay also shows off his 11-ton steam engine built in 1860, back when pigs had to be slaughtered to keep it lubricated. In northern Nevada, fire up a coal burning boiler and get a 100-year-old steam locomotive chugging across the rugged landscape. In New Orleans, board an authentic paddlewheel steamboat. Trek to the Southern California desert where geothermal steam rushes up from the ground and drives electricity producing turbines, powering over 300,000 homes. In New York City, find out why manmade steam surges into some of the world's most famous skyscrapers. Steam clean some very dirty machines, and do a little laundry, too. And ride a steam-driven carousel and play with some strange, steam-powered robots that are part of a movement called--what else--"steampunk."

Millions of drivers travel the world's superhighways each year. See a multi-billion dollar expansion project in Houston, Texas where a stretch of superhighway is being widened to 20 lanes. Take a ride atop the High-Five, a 12-story, five-level interchange that's become the latest Dallas tourist attraction. Then it's off to China's 28,000-mile National Trunk Highway System. Discover how a single distracted driver can cause a major traffic jam. Finally, play a cutting-edge video game that's training emergency personnel how to unclog a clogged superhighway.

In Pennsylvania, our movers must lift an historic 1938 diner out of a building that has covered it for more than 50 years. But moving the cherished landmark unscathed will pose quite a challenge for everyone involved. Meanwhile, a determined mining historian must rescue a gigantic 1923 steam shovel that has been hidden high up in the Colorado Rockies. Will 30 years of sludge and rugged terrain stop this move before it even begins?

Got something strange to deliver? From pizza to packages, we'll show you how it's packed, labeled and shipped. Head down the highway carrying gigantic wind turbine blades. See how UPS got China's invaluable terra cotta warriors to a Los Angeles art museum. Deliver luxury yachts aboard a submersible carrier ship. Ride to the track with prized thoroughbreds on their own special jet. Want dinner and a movie? Sounds like a visit to Netflix headquarters and Papa John's Pizza. Ride radical with bike messengers in New York City, and deliver a donor kidney to a waiting hospital. Take a tour of the UPS Worldport hub in Louisville, Kentucky, a mammoth center with delivery docks for 100 jets, and handles 1.2 million packages a day.

Explore collisions that shake our world from the astronomic to the subatomic. Discover breakthroughs that could make the deadly sport of professional auto racing safer and visit a motorcycle crash test facility and examine two-wheeled accidents in detail. Meet a skydiver who survived a crash to earth from 11,000 feet. An asteroid crashing to earth could destroy our planet--watch as NASA's Near Earth Asteroid Tracking team hunt down dangerous asteroids. Finally learn about scientist's who are creating crashes with colliding subatomic particles in the world's largest machine. Will they unlock the secrets of the universe--or accidentally open a black hole?

Sink your teeth into the razor sharp world of saws. Cut across the centuries to discover how the Egyptians arduously sawed stone as compared to modern saws that slice through limestone like butter. Saws have been used as instruments of torture and tools for surgery. They are imperative for construction, salvage, demolition, and they even make music. Whether they have teeth of steel, carbide or diamond, you will be on the cutting edge of successful sawing.

A versatile yet toxic metal, lead has served mankind for 6,000 years. Explore the vast mines where heavy machinery extracts and refines lead. Visit a car battery factory that makes a superior battery from pure lead. See how a team of experts safely remove harmful lead products from homes and businesses. How can a metal as dark as lead make lead crystal not only sparkle, but manage to stay transparent?

Four and a half billion years ago the Earth formed from dust in space to become a molten ball of rock orbiting the Sun. This episode travels back in time to investigate how the fledgling planet survived a cataclysmic cosmic collision with another world, how molten rock solidified to land, how our oceans filled with water and how life arrived on Earth. Geologists study the oldest rocks on Earth and meteorites from outer space to solve the greatest geological mystery of all--the Birth of the Earth.

As the Cold War reached its boiling point the US began to make plans to protect the country and the president. Elaborate defense preparations were made in the event of nuclear war. Highly secret bunkers were constructed and a covert shadow government program was born. Now these newly opened bunkers are brought into view... in some of the most unexpected places imaginable.

In America's heartland, few structures are as iconic as the country barn and the local church. In Nebraska, our team attempts to transport an historic gothic horse barn to a new farm. Working in sub-zero temperatures, they'll have to maneuver the massive structure through 26 miles of extremely narrow, unpaved country roads to reach their destination. And in Texas, a 115-year-old church has to be cut into five pieces before being relocated to a new spot two miles away. Will our Mega Movers be able to reassemble this cherished chapel and preserve it for future congregations?
