Kingda Ka redefines thrill rides with record-breaking speed and height.

Upstop wheels apply friction under the tracks to prevent roller coasters from derailing during zero-G drops and turns.

A hidden catapult launch system propels the 10-ton coaster up a 90-degree incline.

Kevlar's strands form hydrogen bonds that stick like glue.

Special chemicals give even water what looks like magical properties.

How the ISS can help us explore and colonize the solar system.

Using advanced robotics and 6,000 workers, Tesla's factory can produce 2,000 electric cars per week.

The "Tortoise" was built by William Grey Walter in 1948 and used sensors for light and movement to form a simple nervous system.

The US Navy's new coastal vessels use the latest technology to achieve amazing speed and agility.

Instead of a propeller and a rudder, LCS ships use high-powered water jets for propulsion and maneuvering.

The new Littoral Combat Ships use a trimaran design for greater speed, agility, and stability.

Amazing statistics about the world's tallest free-standing tower.

The tower is almost double the height of Chicago's Hancock Center -- but on a footprint 51% smaller.

Sound mirrors helped Great Britain detect enemy aircraft during World War One.

Located in Cornwall, England, these biomes are home to many diverse climates and environments.

Did you know billiard balls were originally made of ivory?

Locks are used for raising and lowering boats between stretches of water of different levels.

How the ISS can help us explore and colonize the solar system.

This building may not look like much, but back in 1796 it was an innovative skyscraper. This was the first time an iron frame was used in a multi-story building, paving the way for modern day architecture.

The architects that built these pagodas hundreds of years ago made each floor flexible enough to survive earthquakes.

Liberty ships carried vital supplies across the Atlantic to Europe during World War 2, but Germans destroyed them in mass.

NASA’s Orion Spacecraft will travel farther than any other crew exploration vehicle in history. Its destination? Mars.

At the time, this machine was the most sophisticated submarine ever created.

Robert Goddard built his rockets using liquid propulsion, a mixture of gasoline and oxygen. The higher the temperature, the greater the thrust.

And it only cost $185 to build.

These specialized ships help create paths by pushing into ice pockets.

Orion’s ginormous solid rocket motor generates 3.6 million pounds of thrust! That’s the equivalent of 14 jumbo jets operating at maximum power.

As we travel farther up through the atmosphere, air gets harder to breath because pressure goes down and the oxygen molecules are more spread out.

The Severn Bridge is one of Britain’s most iconic engineering marvels. Its key to combating high winds is its unique bridge deck shape.

The Millau Viaduct is the tallest bridge on Earth. It measures 1,125 feet tall, 1.5 miles long, and the bridge deck sits nearly 900 feet above the ground.
