The Boys create an armored vehicle out of an old truck, and armor made of beer cans, then try to blow it up to see if they can create a bombproof pickup.

The Rednecks create a new type of rocket fuel with a hillbilly whiskey still; but can it fire off a monster model rocket, fueled only with moonshine?

The Rednecks aim to build a lightweight, bullet-proof suit that can augment human strength and fire weapons.

The guys turn their sights to underwater exploration -- building a homemade submarine out of a 4 x 4 plastic container farmers use to store fertilizer... and beer kegs, of course.

In his day job at the U.S. Army Space and Missile Defense Command, Travis has explored ways to protect the Earth from collision with an asteroid, but outside the office he'll actually put some of these ideas to the test.

Most scientists think a manned mission to Mars would take at least one and a half years and billions of dollars, but Travis thinks it can be done faster and cheaper.

The Rednecks build a massive radio telescope out of junkyard parts, in an attempt to pick up signals from distant galaxies.

The team create a floating "alternate energy power plant" out of old car parts and a waterwheel that creates all the energy required for a "Redneck Rec Room."

The guys build a solar thermal rocket engine out of old satellite dishes to test out a free energy source that could travel between the stars - or power an old fishing boat.

Travis and the guys compete in NASA's Great Moonbuggy Race - an international competition to create a human-powered lunar vehicle designed to fit aboard a space capsule. Engineering teams around the world spend years designing entries but the Rednecks build theirs in one weekend. After all, Daddy did work on the original Apollo space program so they should have a leg up.

With NASAs shuttle program now defunct, the Rednecks decide to build their own big ass rocket. Staying true to their redneck roots, the team uses whatever they can find, including a farmers abandoned water tank and an old safety ladder, to craft a 700-pound rocket. But they have to buy the largest rocket engines you can get without being in the government.

After 170 killer tornados tear through the South in just two days, the Rocket City Rednecks build a "tornado-proof outhouse" that can withstand F5 winds.

The Rednecks put on a Fourth of July fireworks display using their own rocket fuel and a self-engineered computer program to remotely control the fireworks.

Energy prices are so high that the Boys want to find a way to create a home that's totally off-the-grid.

Using Pete and Travis's experience in military armor and Daddy and Michael's weaponry skills, the Rednecks create a fully-armored war-wagon mounted with a flame thrower and a giant potato cannon, suitable for hunting deer or chasing off invaders.

The Rednecks experiment with the physics of slingshots and trebuchets, then rig a "Super-treb" with a pulley system and weather balloo... that looks more like a massive slingshot than a launch vehicle.

Old sci-fi magazines once promised a Jetsons-style Hovercraft for everyone - but a redneck would prefer a "loungechair hovercraft.

The Stealth Helicopter used in the Bin Laden assault gets Michael thinking - can he avoid another speeding ticket with a "stealth vehicle" that should be completely invisible to radar?

Nothing is more redneck-y than a tailgate party, but Travis wants to use rocket science to turn the Ford Superduty into the ultimate in portable entertainment and food production for NASCAR.

The Rednecks enter a NASA contest with the hopes of launching a man-capable rocket 1 mile into the sky. The custom 20-foot-tall missile boasts two engines and about 3,000 pounds of thrust fueled by a mixture of ammonium perchlorate and aluminum. The goal: Once the rocket reaches 1 mile, explosive charges will shoot a parachute out and allow the capsule, and the test dummy, to float safely back to earth.

The Rednecks fly to L.A. to visit the garage where Jay keeps his personal collection of classic vehicles, and to help him build a steam catapult that will launch a car forward, just like an aircraft carrier catapult-launches jet fighters.

Travis draws inspiration from an experiment he did as a child, while Rog gets his idea from old western movies. Armed with toilet cleaner and welding gas, Team Travis and Team Rog face off, testing their best backwoods bomb creations on small outhouses. The reward? The winner gets to use his invention to blow up a friend's old barn.

Borrowing an 825-gallon barrel from a neighbor's farm, Travis and the boys fortify the pod walls with layers of plywood, laminate, heat-resistant tiles and of course... spray foam. Then they install car seats on the interior to support two passengers and paddle wheels on the sides... just in case they are swept out to sea. To test its' durability, Travis and Rog climb in and plan to complete a rugged obstacle course complete with a cement wall, sharp metal hurdles and a lake. But things don't go as planned, and the survival pod is really put to a survival test! "I screamed like a little girl," says Travis.

It's rare in the hobby rocket world, but a hybrid rocket has more control because it combines two forms of fuel - a solid and a gas.
