Former KGB agent Alexander Litvineko is a critic of Russia and possible MI6 informant living in London when he falls seriously ill in 2006. Re-tracing his steps police and doctors begin to suspect poisoning.

Drugs are reaching our shores in strange half-submarines, designed to challenge our high-tech tools to stop them. It’s a high-stakes war on the water.

Old school assets like diamonds need layers of high-tech protection. Even then, you'll find some dedicated crews with the patience and sophistication to craft a major heist.

See how a master thief and his team researched people's lives to gain information allowing them access to their bank accounts.

High tech changes were made to our currency in the '90s to deter counterfeiting, but undercover FBI agents in 2014 come across fake bills so perfect they're dubbed "superbills."

Dan Riskin reports from Mission Control where the Pluto Fly By has happened. Now we wait for it to turn and take more images.

Why push the limits of the universe? We just want to know what's out there to be discovered. What would it be like to see Pluto.

Did you know Bill Nye, along with the Planetary Society, was one of the first to advocate for the New Horizons mission. He can't WAIT to see what it finds.

We've seen it done in the movies - the perfect car slide in between two parked cars. Think of it as an adult slip n' slide. They guys start by testing pavement lubricants to see what works.

Kevin and Grant have built two versions of their trash can rocket and in true scientific method, they test them out without the propellants first to see if they are air-worthy.

Kevin bets Grant they can build a workable concrete canoe. Despite explaining the science behind how it could work, Grant is dubious. A steak dinner is on the line.

Before they start building their rocket powered skateboard, Grant and Kevin have too much fun doing thrust tests with leaf blowers and fire extinguishers. But, they form a plan.

The guys are inspired to see how many G-forces they can pull on a handmade merry go round powered with a motorcycle. They wisely try the first test with sandbags.

Kevin and Grant have completed the build of their electromagnetic gravity defying boots. Kevin takes the first turn and finds out it takes more than science to make them work.

Kevin and Grant want to do lawnmower jousting right, from armor to weaponry. The first step is comprehensive tests for the best jousting pole.

The guys are building their own "mini-weapons" to compete for accuracy, durability and distance. After Grant bends the rules, the game is on to build anything that will win.

The guys decide they can one up some epic cannon fails with their own homemade Gatling gun, customized to shoot meatballs. Check out the build of both meat and firepower.

After Grant and Kevin watch some three-wheeled destruction on the internet, they brainstorm how they could do it better - with motorized trikes.

After viewing typical science fair style homemade volcanoes, Kevin and Grant head into the field to build a giant version, complete with the three phases of volcanic explosion.

The guys are happy with their soapbox racer built to go off-road, but as always they want to test it before it goes into the field. They use Kevin’s street, curbs, and a bit of garden to start.

Kevin and Grant weld an air cannon in Kevin’s garage to break Don Meredith’s football passing record of 83 yards. They bring the cannon to the field for a "slug" test. Is it record worthy?
